Abstract :
Several approaches by which two-way CATV transportation may be achieved are reviewed. The system performance tradeoffs involved for both single-and dual-cable plants are examined. The possible performance that results from some of these tradeoffs is presented, based on both theoretical and empirical data. These include cross-modulation, carrier-to-noise ratio, and group-delay variation as dependent upon system size, channel loading, amplifier tolerance, and crossover frequency.
