Fiber optic CATV transportation is achieving higher performances standards and lower cost with the utilization of the latest break throughs in VSB-AM and PCM technological. Studies have shown that VSB-AM fiber optic transmission provides an economical means for the transportation of high count CATV channels. Fiber Optic CATV transporation using VSB-AM trunk distribution in conjunction with PCM super trunking can provide a cost effective method of distributing high quality CATV signal to a large distribution area.
To support this hypothesis Sumitomo investigated the technical aspects of this transportation concept. This paper summarizes the following experimental tests;
We are also proposing high count base band video signal distribution using PCM equipment operating at 1.2 Gbps and 2.4 Gbps providing un-compressed transmission of high channel capacity per fiber distribution.
