Abstract :
156 Mbit/s fiber-optic video transmission equipment employing an SDH (synchronous digital hierarchy)/SONET (synchronous optical network) framework has been developed for contribution and primary distribution transport. It can transmit a 1-channel NTSC video signal and 4-channel audio signals with contribution quality. By adopting 10-bit quantizing resolution for the video signal, a signal-to-noise ratio (SNR) of more than 60 dB (unweighted) is achieved. The jitter issue due to the pulse stuffing multiplexing of the video data is examined in detail. By using SDH interface LSIs and an integrated optical transceiver, small size and low power consumption are realized. This equipment can also organize a flexible video transmission system with ease by connecting to SDH/SONET networks
