Fiber Cable Concepts
Fiber Optics and Fiber Optic Cable are the core technologies at the heart of the T-POV
Robotic Camera Link System. The T-POV System features 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. The theory and operation of Fiber Optics is
beyond the scope of this document, but you need to be aware of the different types of
Fiber Optic Cable and Fiber Optic Cable Connectors.
Fig. 2-1: Tactical Fiber Optic Cable Cross-section (Illustrative only)
Tactical Fiber cable is heavy duty; Kevlar protected and capable of carrying T-POV signals
extended distances. The cable can generally withstand a variety of environmental hazards
(such as being crushed or run-over). When used on Portable Fiber Reels, Tactical Fiber can
be used in the field in lengths of up to 2000 feet.
Fig. 2-2: Hybrid Fiber Optic Cable Cross-section (Illustrative only)
Hybrid Fiber Cable has the same Fiber Optic characteristics with the addition of copper
cables, which 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
than Tactical Fiber Cable.
