Fiber Cable Concepts
Fiber Optics and Fiber Optic Cable are the core technologies at the heart of the
CopperHead 3404 Transceiver 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 CopperHead System. The theory and operation of
Fiber Optics is beyond the scope of this document: this document explains the different
types of Fiber Optic Cable and Fiber Optic Cable Connectors.
Fiber Optic Cable
Fig. 2-1: Tactical Fiber Optic Cable Cross-section
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.
