Optical Fiber Structures 0 comments
On the other hand, the quartz fiber used for telephone lines uses the graded index (GI) structure for increased transmission volume.
In GI-POF, the index of refraction progressively increases toward the center of the optical fiber. Therefore, it utilizes the principle of refraction, not reflection as in the previous example.
This method is the same as what occurs when light refracts at the surface of water. GI fiber uses this principle to progressively change the track of the light to contain it within the fiber.
This type of fiber is suitable for high-speed, high-volume transmission.
The only GI-POF on the market today is the EskaGIGA manufactured by Mitsubishi Rayon.
Multi step structure fiber uses the both of the above principles for transmission. As its name indicates, the structure uses multiple step indexes (the �eS�f part of the SI).
Although the basic principle is the same as that of SI-POF, because the index of refraction changes in multiple steps, the locus of the light is shifted toward the center at the same time.
This structure was recognized as a simple solution to increasing bandwidth, and in 1999, Mitsubishi Rayon developed and successfully tested Eska-miu , the first multi step index fiber.
Since POF is for consumers, there is a constant demand for this fiber to remain at reasonable prices. The multi step index structure can be mass produced much easier than GI-POF. Also, since it can easily be applied to varying bandwidths by changing the number of steps, it has the added benefit of simple conversion to larger capacities in the future.
Mitsubishi Rayon proposes the Eska-miu, rather than the higher transmission capacity GI structure EskaGIGA, as the backbone for home networks not only because the Eska-miu satisfies bandwidth requirements, but because we feel that the superior productivity of the multi step structure and cost performance are greater concerns for home networks.

here are some common fiber cable types
Epoxy & Polish
Epoxy & polish style connectors were the original fiber optic connectors. They still represent the largest segment of connectors, in both quantity used and variety available. Practically every style of connector is available including ST, SC, FC, LC, D4, SMA, MU, and MTRJ. Advantages include:
• Very robust. This connector style is based on tried and true technology, and can withstand the greatest environmental and mechanical stress when compared to the other connector technologies.
• This style of connector accepts the widest assortment of cable jacket diameters. Most connectors of this group have versions to fit onto 900um buffered fiber, and up to 3.0mm jacketed fiber.
• Versions are. available that hold from 1 to 24 fibers in a single connector.
Installation Time: There is an initial setup time for the field technician who must prepare a workstation with polishing equipment and an epoxy-curing oven. The termination time for one connector is about 25 minutes due to the time needed to heat cure the epoxy. Average time per connector in a large batch can be as low as 5 or 6 minutes. Faster curing epoxies such as anaerobic epoxy can reduce the installation time, but fast cure epoxies are not suitable for all connectors.
Skill Level: These connectors, while not difficult to install, do require the most supervised skills training, especially for polishing. They are best suited for the high-volume installer or assembly house with a trained and stable work force.
Costs: Least expensive connectors to purchase, in many cases being 30 to 50 percent cheaper than other termination style connectors. However, factor in the cost of epoxy curing and ferrule polishing equipment, and their associated consumables.
Pre-Loaded Epoxy or No-Epoxy & Polish
There are two main categories of no-epoxy & polish connectors. The first are connectors that are pre-loaded with a measured amount of epoxy. These connectors reduce the skill level needed to install a connector but they don't significantly reduce the time or equipment need-ed. The second category of connectors uses no epoxy at all. Usually they use an internal crimp mechanism to stabilize the fiber. These connectors reduce both the skill level needed and installation time. ST, SC, and FC connector styles are available. Advantages include:
• Epoxy injection is not required.
• No scraped connectors due to epoxy over-fill.
• Reduced equipment requirements for some versions.
Installation Time: Both versions have short setup time, with pre-loaded epoxy connectors having a slightly longer setup. Due to curing time, the pre-loaded epoxy connectors require the same amount of installation time as standard connectors, 25 minutes for 1 connector, 5-6 minutes average for a batch. Connectors that use the internal crimp method install in 2 minutes or less.
Skill Level: Skill requirements are reduced because the crimp mechanism is easier to master than using epoxy. They provide maximum flexibility with one technology and a balance between skill and cost.
Costs: Moderately more expensive to purchase than a standard connector. Equipment cost is equal to or less than that of standard con¬nectors. Consumable cost is reduced to polish film and cleaning sup-plies. Cost benefits derive from reduced training requirements and fast installation time.
No-Epoxy & No-Polish
Easiest and fastest connectors to install; well suited for contractors who cannot cost-justify the training and supervision required for standard connectors. Good solution for fast field restorations. ST, SC, FC, LC, and MTRJ connector styles are available. Advantages include:
• No setup time required.
• Lowest installation time per connector.
• Limited training required.
• Little or no consumables costs.
Installation Time: Almost zero. Its less than 1 minute regardless of number of connectors.
Skill level: Requires minimal training, making this type of connector ideal for installation companies with a high turnover rate of installers and/or that do limited amounts of optical-fiber terminations.
Costs: Generally the most expensive style connector to purchase, since some of the labor (polishing) is done in the factory. Also, one or two fairly expensive installation tools may be required. However, it may still be less expensive on a cost-per-installed-connector basis due to lower labor cost.
Multi-mode Fiber Optic 0 comments
Fiber with large core diameter (greater than 10 micrometers) may be analyzed by geometric optics. Such fiber is called multi-mode fiber, from the electromagnetic analysis (see below). In a step-index multi-mode fiber, rays of light are guided along the fiber core by total internal reflection. Rays that meet the core-cladding boundary at a high angle (measured relative to a line normal to the boundary), greater than the critical angle for this boundary, are completely reflected. The critical angle (minimum angle for total internal reflection) is determined by the difference in index of refraction between the core and cladding materials. Rays that meet the boundary at a low angle are refracted from the core into the cladding, and do not convey light and hence information along the fiber. The critical angle determines the acceptance angle of the fiber, often reported as a numerical aperture. A high numerical aperture allows light to propagate down the fiber in rays both close to the axis and at various angles, allowing efficient coupling of light into the fiber. However, this high numerical aperture increases the amount of dispersion as rays at different angles have different path lengths and therefore take different times to traverse the fiber. A low numerical aperture may therefore be desirable.
Optical fiber types.
In graded-index fiber, the index of refraction in the core decreases continuously between the axis and the cladding. This causes light rays to bend smoothly as they approach the cladding, rather than reflecting abruptly from the core-cladding boundary. The resulting curved paths reduce multi-path dispersion because high angle rays pass more through the lower-index periphery of the core, rather than the high-index center. The index profile is chosen to minimize the difference in axial propagation speeds of the various rays in the fiber. This ideal index profile is very close to a parabolic relationship between the index and the distance from the axis.

Other uses of optical fibers 0 comments
Optical fiber is also used in imaging optics. A coherent bundle of fibers is used, sometimes along with lenses, for a long, thin imaging device called an endoscope, which is used to view objects through a small hole. Medical endoscopes are used for minimally invasive exploratory or surgical procedures (endoscopy). Industrial endoscopes (see fiberscope or borescope) are used for inspecting anything hard to reach, such as jet engine interiors.
An optical fiber doped with certain rare-earth elements such as erbium can be used as the gain medium of a laser or optical amplifier. Rare-earth doped optical fibers can be used to provide signal amplification by splicing a short section of doped fiber into a regular (undoped) optical fiber line. The doped fiber is optically pumped with a second laser wavelength that is coupled into the line in addition to the signal wave. Both wavelengths of light are transmitted through the doped fiber, which transfers energy from the second pump wavelength to the signal wave. The process that causes the amplification is stimulated emission.
Optical fibers doped with a wavelength shifter are used to collect scintillation light in physics experiments.
Optical fiber can be used to supply a low level of power (around one watt) to electronics situated in a difficult electrical environment. Examples of this are electronics in high-powered antenna elements and measurement devices used in high voltage transmission equipment
Single-mode Fiber Optic 0 comments
The waveguide analysis shows that the light energy in the fiber is not completely confined in the core. Instead, especially in single-mode fibers, a significant fraction of the energy in the bound mode travels in the cladding as an evanescent wave.
The most common type of single-mode fiber has a core diameter of 8–10 micrometers and is designed for use in the near infrared. The mode structure depends on the wavelength of the light used, so that this fiber actually supports a small number of additional modes at visible wavelengths. Multi-mode fiber, by comparison, is manufactured with core diameters as small as 50 micrometers and as large as hundreds of micrometres. The normalized frequency V for this fiber should be less than the first zero of the Bessel function J0 (approximately 2.405).
Manufacturing of Fiber Optic 0 comments
Glass optical fibers are almost always made from silica, but some other materials, such as fluorozirconate, fluoroaluminate, and chalcogenide glasses, are used for longer-wavelength infrared applications. Like other glasses, these glasses have a refractive index of about 1.5. Typically the difference between core and cladding is less than one percent.
Plastic optical fibers (POF) are commonly step-index multi-mode fibers with a core diameter of 0.5 millimeters or larger. POF typically have higher attenuation co-efficients than glass fibers, 1 dB/m or higher, and this high attenuation limits the range of POF-based systems.
Process
Standard optical fibers are made by first constructing a large-diameter preform, with a carefully controlled refractive index profile, and then pulling the preform to form the long, thin optical fiber. The preform is commonly made by three chemical vapor deposition methods: inside vapor deposition, outside vapor deposition, and vapor axial deposition.[10]
With inside vapor deposition, a hollow glass tube approximately 40 cm (16 inches) in length known as a "preform" is placed horizontally and rotated slowly on a lathe, and gases such as silicon tetrachloride (SiCl4) or germanium tetrachloride (GeCl4) are injected with oxygen in the end of the tube. The gases are then heated by means of an external hydrogen burner, bringing the temperature of the gas up to 1900 kelvins (1600 °C, 3000 °F), where the tetrachlorides react with oxygen to produce silica or germania (germanium dioxide) particles. When the reaction conditions are chosen to allow this reaction to occur in the gas phase throughout the tube volume, in contrast to earlier techniques where the reaction occurred only on the glass surface, this technique is called modified chemical vapor deposition.
The oxide particles then agglomerate to form large particle chains, which subsequently deposit on the walls of the tube as soot. The deposition is due to the large difference in temperature between the gas core and the wall causing the gas to push the particles outwards (this is known as thermophoresis). The torch is then traversed up and down the length of the tube to deposit the material evenly. After the torch has reached the end of the tube, it is then brought back to the beginning of the tube and the deposited particles are then melted to form a solid layer. This process is repeated until a sufficient amount of material has been deposited. For each layer the composition can be modified by varying the gas composition, resulting in precise control of the finished fiber's optical properties.
In outside vapor deposition or vapor axial deposition, the glass is formed by flame hydrolysis, a reaction in which silicon tetrachloride and germanium tetrachloride are oxidized by reaction with water (H2O) in an oxyhydrogen flame. In outside vapor deposition the glass is deposited onto a solid rod, which is removed before further processing. In vapor axial deposition, a short seed rod is used, and a porous preform, whose length is not limited by the size of the source rod, is built up on its end. The porous preform is consolidated into a transparent, solid preform by heating to about 1800 kelvins (1500 °C, 2800 °F).
The preform, however constructed, is then placed in a device known as a drawing tower, where the preform tip is heated and the optic fiber is pulled out as a string. By measuring the resultant fiber width, the tension on the fiber can be controlled to maintain the fiber thickness.

Termination and splicing of fiber 0 comments
Optical fibers are connected to terminal equipment by optical fiber connectors. These connectors are usually of a standard type such as FC, SC, ST, LC, or MTRJ.
Optical fibers may be connected to each other by connectors or by splicing, that is, joining two fibers together to form a continuous optical waveguide. The generally accepted splicing method is arc fusion splicing, which melts the fiber ends together with an electric arc. For quicker fastening jobs, a "mechanical splice" is used.
Fusion splicing is done with a specialized instrument that typically operates as follows: The two cable ends are fastened inside a splice enclosure that will protect the splices, and the fiber ends are stripped of their protective polymer coating (as well as the more sturdy outer jacket, if present). The ends are cleaved (cut) with a precision cleaver to make them perpendicular, and are placed into special holders in the splicer. The splice is usually inspected via a magnified viewing screen to check the cleaves before and after the splice. The splicer uses small motors to align the end faces together, and emits a small spark between electrodes at the gap to burn off dust and moisture. Then the splicer generates a larger spark that raises the temperature above the melting point of the glass, fusing the ends together permanently. The location and energy of the spark is carefully controlled so that the molten core and cladding don't mix, and this minimizes optical loss. A splice loss estimate is measured by the splicer, by directing light through the cladding on one side and measuring the light leaking from the cladding on the other side. A splice loss under 0.1 dB is typical. The complexity of this process makes fiber splicing much more difficult than splicing copper wire.
Mechanical fiber splices are designed to be quicker and easier to install, but there is still the need for stripping, careful cleaning and precision cleaving. The fiber ends are aligned and held together by a precision-made sleeve, often using a clear index-matching gel that enhances the transmission of light across the joint. Such joints typically have higher optical loss and are less robust than fusion splices, especially if the gel is used. All splicing techniques involve the use of an enclosure into which the splice is placed for protection afterward.
Fibers are terminated in connectors so that the fiber end is held at the end face precisely and securely. A fiber-optic connector is basically a rigid cylindrical barrel surrounded by a sleeve that holds the barrel in its mating socket. The mating mechanism can be "push and click", "turn and latch" ("bayonet"), or screw-in (threaded). A typical connector is installed by preparing the fiber end and inserting it into the rear of the connector body. Quick-set adhesive is usually used so the fiber is held securely, and a strain relief is secured to the rear. Once the adhesive has set, the fiber's end is polished to a mirror finish. Various polish profiles are used, depending on the type of fiber and the application. For single-mode fiber, the fiber ends are typically polished with a slight curvature, such that when the connectors are mated the fibers touch only at their cores. This is known as a "physical contact" (PC) polish. The curved surface may be polished at an angle, to make an "angled physical contact" (APC) connection. Such connections have higher loss than PC connections, but greatly reduced back reflection, because light that reflects from the angled surface leaks out of the fiber core; the resulting loss in signal strength is known as gap loss. APC fiber ends have low back reflection even when disconnected.

Bluetooth® technology is a cutting-edge open specification that enables short-range wireless connections between desktop and notebook computers, handhelds, personal digital assistants, mobile phones, camera phones, printers, digital cameras, headsets, keyboards and even a computer mouse. Bluetooth wireless technology uses a globally available frequency band (2.4GHz) for worldwide compatibility. In a nutshell, Bluetooth technology unplugs your digital peripherals and makes cable clutter a thing of the past. With Bluetooth technology integrated in Mac OS X, you can easily connect your Apple computer with your Palm OS-based handheld device, mobile phone and other peripherals with Bluetooth technology — and do it wirelessly, within a 30-foot range.
Unwire your life
With the Bluetooth feature turned on, your Mac can perform a file transfer or synchronization. From the Bluetooth menu, you can choose to send a file or browse a device, simply and quickly. Or click the Sync button in iSync to update your mobile phone or Palm OS handheld. For extra security, you can stipulate that only trusted devices talk to your Mac, and 128-bit over-the-air encryption is also available.
Your Mac and your GSM/GPRS mobile phone with Bluetooth technology make each other more useful. Using iSync, you can keep your phone updated with your contacts’ numbers without having to type in their info on a tiny keypad. Keep the information in the more manageable Address Book on your Mac instead. Address Book also lets you send SMS messages over your mobile phone, and will display SMS messages from your phone on your Mac. You can also use your Mac to respond to voice calls.
Use your Bluetooth-enabled Mac to print document and digital images to a select printer that supports Bluetooth technology. Or use a Bluetooth headset to talk to your friends and colleagues during an iChat AV session.
Your Mac can also use Bluetooth technology to communicate with your Palm OS handheld, like the Tungsten T3. You can perform a HotSync operation without cables. Or send your business card or calendar events directly to a colleague’s handheld — using Bluetooth technology. The standard vCal and vCard formats let this work on both Palm and PocketPC handhelds with Bluetooth technology.
And for a whizzy trick that’s sure to impress, send an instant iCard with your own image taken by your mobile phone. Use a camera phone such as the Nokia 6600 or the Sony Ericsson P800 to take pictures, download them to your Mac over a Bluetooth connection, create an iCard, then send it using your phone’s GPRS connection.
The Apple Wireless Keyboard and Apple Wireless Mouse use Bluetooth technology to free you and your Mac from the physical restraints of tethering cables and crowded peripheral ports.
Apple’s Bluetooth implementation is the latest in a series of bold strategic moves that have caused tectonic shifts in the computer industry — and greatly benefited customers. Apple established USB as the standard peripheral interface with the launch of the first iMac in 1998. Then Apple established the 802.11 wireless networking standard with the launch of the iBook and AirPort in 1999. In 2003 Apple launched AirPort Extreme, based on the new 802.11g high-speed wireless technology. Now Bluetooth further strengthens the dominant position of the Mac in wireless communications, preserving Apple’s reputation for being first to market with innovative technology integrated right into the operating system.
Mac OS X lets you wirelessly transfer files between computers — even Mac to PC — using the Bluetooth File Exchange utility. It’s even possible to browse selected devices and retrieve files remotely. Apple recommends the use of AirPort and AirPort Extreme for wireless networking, however, for anything but the smallest files.
Where to learn more about Bluetooth
There are now over 1,800 adopter members of the Bluetooth Special Interest Group (SIG) who’ve pledged their support to this standard. Apple is one of them.

A computer is a machine that manipulates data according to a list of instructions.The first devices that resemble modern computers date to the mid-20th century (1940–1945), although the computer concept and various machines similar to computers existed earlier. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers (PC).[1] Modern computers are based on tiny integrated circuits and are millions to billions of times more capable while occupying a fraction of the space.[2] Today, simple computers may be made small enough to fit into a wristwatch and be powered from a watch battery. Personal computers, in various forms, are icons of the Information Age and are what most people think of as "a computer"; however, the most common form of computer in use today is the embedded computer. Embedded computers are small, simple devices that are used to control other devices — for example, they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and children's toys.
Gartner Says IT Spending Worse Than After Dot-Com Bust 0 comments
With the global economy tanking, IT spending this year will drop to a level much worse than what was seen following the dot-com bust in 2001, a market research firm said Tuesday.
Companies worldwide will spend 3.8% less on IT than in 2008, or $3.2 trillion compared with nearly $3.4 trillion, Gartner said. When the Internet investment bubble burst eight years ago, IT spending fell by 2.1%.

Gartner has been lowering its IT spending estimates for months. Last October, the research firm said its "worst-case scenario" called for a 2.3% increase in IT spending for 2009. By February, Gartner had lowered its prediction to an increase of 0.5%.
The latest numbers reflect another dramatic across-the-board lowering of Gartner's forecast for the four IT segments: computing hardware, software, IT services, and telecommunications. A major contributor to the decline is the drop in the global gross domestic product, or GDP, which is expected to fall by 1.2% this year after expanding by 2.3% last year.
With the exception of software, which will be nearly flat, all the other segments will see declines, led by computing hardware, which will fall 14.9% to $324.3 billion, Gartner said.
The drop in computer spending is caused by a slowdown in new sales in emerging markets and replacement sales in mature markets among businesses and consumers. In addition, virtualization, which enables companies to consolidate more business applications on a single server, also is expected to contribute to the sales drop.
As a result, virtualization software sales are expected to be a bright spot in the gloomy forecast. At $4 billion in annual sales, the virtualization market is a sliver of overall IT spending. Nevertheless, companies are expected to spend 33% more on the technology than last year. Sales through 2013 are expected to increase at a compound annual growth rate of about 30%, Gartner said.
"People want to optimize their cost and virtualization is a great way to squeeze out more value in what you already have in house," Garner analyst Fabrizio Biscotti said during a Web briefing for clients and media
Desktop Computer 0 comments
Prior to the wide spread of PCs a computer that could fit on a desk was considered remarkably small. Today the phrase usually indicates a particular style of computer case. Desktop computers come in a variety of styles ranging from large vertical tower cases to small form factor models that can be tucked behind an LCD monitor. In this sense, the term 'desktop' refers specifically to a horizontally-oriented case, usually intended to have the display screen placed on top to save space on the desk top. Most modern desktop computers have separate screens and keyboards.

HP Launches Mac-Compatible Home Servers 0 comments
HP launched the newest generation of its MediaSmart Home Servers. The big news? The MediaSmart servers are now Mac-compatible.
HP is pushing its MediaSmart servers as a, well, smart way for consumers to connect individual computers and organize media files in one central location.
"A growing number of digital-savvy households have both Windows and Mac computers, with hundreds and sometimes thousands of media files and documents scattered across these devices," said Jason Zajac, vice president of strategy, Worldwide Attach Group, HP, in a statement. "The HP MediaSmart Server protects, stores and organizes this content from anywhere on a network so consumers can access and share it any place they are connected."
The Price Is Right
The two new MediaSmart Home Server models, the EX485 and the EX487, will be available for pre-order on January 5, and will ship in February 2009. Pricing starts at $599 for the EX485 and $749 for the EX487.
EX485
The HP MediaSmart Home Server EX485 comes loaded with Microsoft Windows Home Server, the price of which Microsoft recently cut by 30 percent. The EX485 has an Intel Celeron 2.0 Ghz 64-bit processor, 2GB of memory, and a 750 GB hard drive in one of its four drive bays.
The EX487 also comes with Microsoft Home Server, an Intel Celeron 2.0 Ghz processor and 2GB of RAM, but doubles the hard drive capacity, giving users a whopping 1.5 terabytes of space, and still leaving two of its four drive bays available for expansion.
The EX485 and the EX487 will automatically back up files on a daily basis, using Apple's Time Machine application for Macs and Microsoft Home Server's Backup program for PCs. Users can easily interact with the MediaSmart server using Control Centers for both PCs and Macs.

HP’s Firebird 803 Mini-Tower Leaked! 0 comments
While the Blackbird 002 was a slick system, it was a bit difficult on the wallet. Thankfully it looks like the minds at HP and Voodoo have been working hard on a spiritual successor, the Firebird 803 that scraps space and expandability for a (presumably) lower price point.
The new smaller version of the behemoth gaming PC will pack a Core 2 Quad Q9550 2.83GHz processor, 4GB RAM, two Nvidia GeForce 9800S cards as well as other big components. HP has also put the power supply outside of the box, allowing them to cool down the chassis a bit easier.
Sadly, the Firebird won’t be expandable at all given its small form factor, and this greatly offsets any potential savings that might be on the price tag.
Here's the reported list of specs:
• NVIDIA nForce 760i SLI chipset• Core 2 Quad Q9550 2.83GHz processor
• 4GB of RAM
• Dual NVIDIA GeForce 9800S cards
• Two 320GB SATA drives
• Blu-ray
• 5-in-1 card reader
• USB, 1 FireWire, 2 eSATA, 1 S/PDIF and 1 DVI dual-link
• Bluetooth
• 802.11n WiFi
Laptop 0 comments
A laptop computer or simply laptop, also called a notebook computer or sometimes a notebook, is a small personal computer designed for mobility. Usually all of the interface hardware needed to operate the laptop, such as parallel and serial ports, graphics card, sound channel, etc., are built in to a single unit. Most laptops contain batteries to facilitate operation without a readily available electrical outlet. In the interest of saving power, weight and space, they usually share RAM with the video channel, slowing their performance compared to an equivalent desktop machine. Intel Atom sales boost global chip market 0 comments
The report, released on Monday, follows a mid-October IDC study, which found Netbooks--the mini-laptops for which the Atom chip is designed--helped the overall EMEA PC market grow 27 percent in the third quarter of 2008 over the same quarter last year, largely fueled by consumer demand.
Netbooks are small, relatively inexpensive laptops that are often purchased as a supplement to an existing desktop or laptop. Mature markets such as the United States and Europe account for some of the highest Netbook sales, according to IDC.
Worldwide shipments of processors for PCs and servers grew 15.8 percent in the third quarter compared with the same period a year ago, with revenue increasing 4 percent to a total of US$8.3 billion, IDC said. By the end of the year, Netbook shipments are expected to exceed 10 million units.
Recent Netbook releases include late-October models from HP and Dell.
Without counting the Atom processor, the increase in shipments would only be about 8 percent. However, this figure is still respectable, said IDC analyst Shane Rau.
"Not considering the effects of Atom, the overall market still grew at a decent pace," Rau said in a statement. "Intel's and AMD's shipments grew at a rate only slightly slower than typical for a third quarter; seasonal demand appeared reasonable up until September. By segment, while the mobile-processor segment grew aggressively, the server segment was soft."
Since September, however, the international financial crisis has grown more serious, and this is likely to have an impact on fourth-quarter figures, IDC said.
On Friday, Intel warned the credit crisis could hurt demand for its chips and lead to the insolvency of key suppliers, potentially resulting in product delays. Intel has forecast its fourth-quarter revenues at between US$10.1 billion and US$10.9 billion, weaker than typically seen in the period running up to Christmas. The company is to publish a mid-quarter update on 4 December.
In the overall x86 market, Intel's share was about 80 percent, up 1.1 percent from the same quarter a year ago, while principal competitor AMD lost 1.2 percent for a total of 18.5 percent. Via Technologies, which concentrates on mobile chips, controlled less than 1 percent of the total market.
In mobile chips, Intel accounted for about 87 percent of the market, AMD 11.5 percent and Via 1.2 percent. Intel shipped about 73.5 percent of all desktop chips, with 26.4 percent for AMD.
AMD gained share over Intel in the server and workstation market, rising less than 1 percent from the previous year to stand at about 14 percent. Intel lost about 1 percent, falling to 85 percent of the segment.
IDC said it would raise its chip forecast through 2008 to 18 percent growth, but said it is expecting to lower its estimates for next year
