Fiber Cable Overview
Fiber Optics and Fiber Optic Cable are the core technologies at the heart of the TelePort 3G
System. The ability to multiplex and de-multiplex multiple ranges of fiber optic signals
carrying SDI, Audio, and Data is what enables the TelePort 3G. The specific theory and
operation of Fiber Optics is beyond the scope of this document.

Tactical Fiber cable is heavy duty, Kevlar protected and capable of carrying CopperHead
signals extended distances. The cable can generally withstand a variety of environmental
hazards such as being crushed or run-over. Tactical Fiber can be used in the field mounted
on Portable Fiber Reels in lengths up to 2000 feet.
Fig. 2-2: Hybrid Fiber Optic Cable Cross-section
Hybrid Fiber Cable has the same Fiber Optic characteristics with the addition of copper
cables. This allows the transmission of power through the cable. This increases weight and
reduces operating distance. Hybrid Fiber Cable also includes a pair of Sense/Signal wires
that allow systems to determine if there is an open or shorted cable. Hybrid Fiber Cable is
also larger in diameter then Tactical Fiber Cable.
