2.1. Fiber Cable Concepts
Fiber Optics and Fiber Optic Cable are the core technologies at the heart of the Telecast Fiber Systems
CopperHead 3400 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. What is important for the end user to be aware of are the different types of
Fiber Optic Cable and Fiber Optic Cable Connectors.
Fiber Optic Cable
Figure 1 - Tactical Fiber Optic Cable Cross-section (Illustrative only)
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.
Figure 2 - Hybrid Fiber Optic Cable Cross-section (Illustrative only)
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
