Abstract :
Broadband-ISDN multiple access networks with individual subscriber nodes operating at a data rate in excess of of 1 GB/s can transmit a total data capacity of tens of Gb/s over a single optical fiber. In this paper we describe a novel, compact optically time-division-multiplexing (OTDM) scheme which can achieve a potential multiplexed data-capacity of several tens of Gb/s without the use of ultra high-speed sources, modulators or drive electronics. The functions of a TDM multiplexer-data modulation, pulse compression, relative time-delay, variable time-slot-interchange (TSI) for switching operations, and the bit-interleaving of multiple data streams-are all combined in a single operation
