Solutions for an evolving world.

Dedicated Fiber Optic Cable

• Single mode Fiber

• In fiber-optic communication, a single-mode optical fiber

(SMF) is an optical fiber designed to carry light only directly

down the fiber

• Multimode Fiber

cable has a little bit bigger diameter, with a common diameters in

the 50-to-100 micron range for the light carry component (in the US

the most common size is 62.5um). Most applications in which Multi-

mode fiber is used, 2 fibers are used (WDM is not normally used on

multi-mode fiber). POF is a newer plastic-based cable which

promises performance similar to glass cable on very short runs, but

at a lower cost.

• Multimode fiber

Gives you high bandwidth at high speeds (10 to 100MBS - Gigabit to

275m to 2km) over medium distances. Light waves are dispersed into

numerous paths, or modes, as they travel through the cable's core

typically 850 or 1300nm.

Typical multimode fiber core diameters are 50, 62.5, and 100

micrometers. However, in long cable runs (greater than 3000 feet

[914.4 meters), multiple paths of light can cause signal distortion at

the receiving end, resulting in an unclear and incomplete data

transmission so designers now call for single mode fiber in new

applications using Gigabit and beyond
