How does it work? Copper Twisted-Wire. Fiber Optic.


Fiber optic refers to the medium and the technology associated with the transmission of information as light impulses along a glass or plastic wire or fiber. Fiber optic wire carries much more information than conventional copper wire and is far less subject to 3Com 3C2000-T Gigabit Adapter interference. Most telephone company long-distance lines are now fiber optic. Transmission on fiber optic wire requires repeating at distance intervals. The glass fiber requires more protection within an outer cable than copper.

For these reasons and because the installation of 3Com 3C2000-T Gigabit Adapter new wiring is labor-intensive, few communities yet have fiber optic wires or cables from the phone company's branch office to local customers. Data is sent over fiber optic cables by a Physics process known as Total Internal Reflection. Consider the image at the right below. A basic knowledge of Optics is assumed.

When light passes from a medium with one index of refraction m1 to another medium with a lower index of refraction m2, it bends or refracts away from an imaginary line perpendicular to the surface normal line. As the angle of the beam through m1 becomes greater with respect to the normal line, 3Com 3C2000-T Gigabit Adapter refracted light through m2 bends further away from the line. If the beam through m1 is greater than the critical angle, then the refracted beam will be reflected entirely back into m1 total internal reflection.

In Physics, the critical angle is described with respect to the normal line. In fiber optics, the critical angle is described with respect to the parallel axis running down the middle of the fiber. In an optical fiber, the light travels through the core m1, high index of refraction by constantly reflecting from the cladding m2, lower index of refraction because the 3Com 3C2000-T Gigabit Adapter of the light is always greater than the critical angle.


Light reflects from the cladding no matter what angle the fiber itself gets bent at, even if it's a full circle! Because the cladding does not absorb any light from the core, the light wave can travel great distances. However, some of the light signal degrades within the fiber, mostly due to impurities in the glass. 3Com 3C2000-T Gigabit Adapter difference under the microscope. Copper's major drawback is that its transmission capability is only Mbps for up to approximately meters.

This is due to the distributed capacitance which is an inherent problem in all copper cable. This means that for any large Local 3Com 3C2000-T Gigabit Adapter Networks wired for copper, such as might be found in an average corporate complex, a series of expensive repeaters must be installed.

Each of these repeaters will also require a corresponding number of wire closets, all taking up valuable real estate. As a result, servicing a malfunctioning device on a copper 3Com 3C2000-T Gigabit Adapter network becomes very complicated, requiring engineers at the switch station, workstation and wiring closet. Fiber optic cable has no such limitations.

The 3Com 3C2000-T Gigabit Adapter bandwidth for multimode fiber is MHz for one kilometer. In a standard office environment, this would eliminate the need for repeaters and extra closet space. The concentrators could be run to a central location in a topography known as "homerunning" and fewer personnel are needed to diagnose and correct a problem.

Furthermore, because of fiber optic cable's greater transfer capabilities, the need for the replacement of a system will not be as frequent as it is for a LAN wired with copper.

This means the product will ship as received by the manufacturer, sealed, with all advertised components, and with the manufacturer warranty. This means the product was tested and repaired as required to meet the standards of the refurbisher, which may or may not be the original manufacturer. In the event that a driver has become damaged it is likely to corrupt other types of components which are in direct association with it and consequently might adversely modify the functioning of a variety of units that are apparently 3Com 3C2000-T Gigabit Adapter related to the initial location.
