Evaluation Of Feed-Forward Amplifiers, Microwave Transmission And Other Long-Distance Methods Of Signal Carriage (1983)
By Donald Z. Dworkin, NYT Cable TV
The advent of 350, 400 and 450 Mhz systems has posed the requirement for improved methods of supertrunk design. The parallel development of feed-forward amplifiers and high channel capacity microwave has opened new possibilities which this paper explores by comparing designs for typical systems by each of these methods. A large range of numbers of channels, bandwidths and numbers of hubs are compared for system performance and costs.
The costs for each type of system are calculated on a per channel basis, per subscriber and per channel, per home. An assessment is made of reliability and operating costs for feed-forward and microwave. A single example each of an FM video and a fiber optic system are included for cost comparison.
