TR-in-FE Cable Specification

C-3

The same cable would have a 500 MHz of bandwidth 
at 1 km (0.625 miles).

A fiber cable with a bandwidth specification of 200 
MHz.km would have only 100 MHz of bandwidth at 
2 km (1.25 miles), which would not support TR-in-FE. 
In this case, another type of fiber which has a band-
width of 155 MHz would be required.
