There are two basic types of Fiber - single mode and multimode. Single mode has a core diameter of 8 to 10 microns and is normally
used for long distance requirements (i.e., interstate) and high bandwidth applications. Multimode, on the other hand, has a core diameter
of 50 or 62.5 microns and is usually used inside buildings or in a campus environment.
In both types of fiber cables, the fibers consist of two parts, a central transparent core region, through which the light travels and an outer
cladding layer. The core and the cladding are typically made of pure silica glass. When you here someone talking about a 62.5 X 125
multimode fiber, they are referring to the measurements of the core and the cladding (the diameter of the core being 62.5 microns and the
diameter of the cladding being 125 microns).
Today the most common fiber questions are: "How far into my building should I run fiber? What kind of limits do I have to be concerned
about, especially for my Gigabit network? What level of multimode high-performance fiber do I need? When am I going to run it to the
desktop? With increasing speeds, how can I ensure that two, five and ten years from now I'll have the capacity I need?"
Td Communications can help answer these questions and we install, terminate and test both multi-mode and single-mode fiber optic
