Abstract :
Emerging standards for highly compressed digital video create interesting possibilities for providing broadcast and switched video services over fiber in the subscriber loop. Experiments are reported which simulate transmission of 200-400 compressed digital video signals using conventional Fabry-Perot lasers and p-i-n diode lightwave receivers. In addition to featuring a robust, low-cost transmission system, compressed digital video networks can offer significant additional advantages, including provisioning of broadcast and switched-video services on a single optical carrier, offering remote service provisioning, and use of video line concentration to significantly reduce the number of switched-video access lines required on each fiber-loop
