Fiber Cable Overview
Fiber Optics and Fiber Optic Cable are the core technologies at the heart of the Telethon 3G
System. The ability to multiplex and de-multiplex a variety of video, audio, and data signals
so that they can be carried over a thin strand of Fiber Optic cable for long distances enables
the Telethon 3G. The specific theory and operation of Fiber Optics is beyond the scope of
this document.
