Synchronous quantized subcarrier multiplexing for transport of video, voice, and data

A quantized subcarrier multiplexing approach for the transmission of video, voice, and data information over optical fiber networks is explored. The basis of this technique is to utilize a single high-speed analog-to-digital converter to digitize a composite analog signal. Conventional subcarrier mu...

Description
Summary:A quantized subcarrier multiplexing approach for the transmission of video, voice, and data information over optical fiber networks is explored. The basis of this technique is to utilize a single high-speed analog-to-digital converter to digitize a composite analog signal. Conventional subcarrier multiplexing methods are used to form the composite from multiple NTSC video, voice, and data signals. The process of synchronous multiplexing, quantization, serialization, transmission, and waveform recovery is explored for an experimental prototype system. Noise performance and the impact on laser linearity requirements are discussed.< >
