An 8 KM Fiber Optic CATV Supertrunk System (1978)
By Whitworth W. Cotten and Dr. C. Richard Patisaul, Harris Corporation & Donald G. Monteith, Cablesystems Engineering
The technical criteria for the design, analysis and hardware implementation of the first major fiber-optic digital CATV supertrunk in North America are presented.
The supertrunk system transmits 12 NTSC color television channels and 12 FM stereo channels over an eight-fiber cable 7.8 km in length. The optical fiber cable is lashed to messenger wires with optical repeaters at 2.8 km intervals. Audio, video and FM signals are digitized and multiplexed into a single 322 Mb/s bit stream modulating an injection laser diode transmitter.
