Abstract: A novel multigigabit, multichannel lightwave network is described which uses subcarrier multiplexing to place multiple information channels and a baseband control channel on a single optical carrier. The control channel uses an FDDI-like token-passing access protocol and a 100 Mb/s control channel to provide efficient access to many Gb/s of information. The subcarrier multiplexed network (SCM-NET) can simultaneously transport many forms of information including variable-length data-grams, ATM-cells, and connection-oriented video traffic. By channelizing the total throughput, the reduction in utilization efficiency caused by propagation delay between nodes is significantly improved relative to conventional single-channel gigabit networks.
