A key advantage of optical fibers over coax for CATV supertrunk is the elimination of trunk amplifiers or repeaters. By substantially reducing the amount of active electronics associated with supertrunk plant, overall reliability is increased and maintenance costs greatly reduced. Warner Amex is evaluating fiber optics for such an application by way of a field trial in its Dallas network. A 16 Km repeaterless link, is overlashed along an existing cable trunk route, to provide supertrunk quality video signals from the East Master Head End to a hub in the downtown Dallas area. A minimum of four video channels per fiber is transmitted by using two wavelengths per fiber with two frequency multiplexed video channels on each wavelength. A description and results to date of this field trial are presented in this paper.
