Includes bibliographical references (pages 38-39). "Recent development of optical fiber waveguides with losses less than 1 dB/km at 950 nm wavelength has created the possibility of transmitting television signals through analogue optical transmission systems for distances extending well beyond 10 km, without the use of repeaters. Analogue systems are attractive because of system simplicity and potential low cost in comparison to digital optical transmission systems. Application of optical fibers to cable television (CATV) systems have been discussed often in the past and two fundamental problems in duplicating the present coaxial cable television system with optical fibers have been identified"--Introduction, page [1]. gccst Cable television gccst Design gccst Digital technology Canada.
