    L-4CFTX 305M - Overview

    The Canare series of 75 ohm Triaxial Cables (L-5CFTX, L-4CFTX, L-7CFTX, 10CFTX-SC), often referred to as triax for short, are a type of electrical cable similar to coaxial cable, but with the addition of an extra layer of insulation and a second conducting sheath. It provides greater bandwidth and rejection of interference than coax. The most common use of triaxial cable is in television industry as a connecting cable between a camera and its CCU. The outer sheath is commonly used as a protective earth conductor. The core provides both power and signal connections, with the return for the power being provided through the inner screen. Through frequency-division multiplexing, the camera can send audio and video signals along the triax while the CCU can send camera control information, such as exposure settings, intercom, return audio and video (usually that of the program), and tally (a signal alerting the operator that their camera is on the air)and power for the camera. Venues that host television productions fairly often, such as sports arenas, will usually have triaxial cables run from the location of the TV truck to common camera locations throughout the building. This is convenient for visiting television crews, who can simply plug into existing cable runs instead of having to run their own cables and remove them after filming.
