WHY FIBER OPTICS?
- The small size of fiber can be a great benefit where current or anticipated space is a concern such as small plenum spaces and beneath computer room floors.
- A 4.5 in. diameter coaxial cable can carry as many as 40,300 duplex (two-way) conversations over short distances while a fiber optic cable which contains 144 fibers in its 0.5 inch diameter structure, has the capacity to carry 24,192 coversations on each fiber pair or nearly 1.75 million calls on all 144 fibers.
