Abstract:

The potential of passive star WDM networks is believed to be extremely high. STARNET is a new broadband optical LAN based on such physical structure. Every STARNET node supports both packet traffic and a high-speed WDM circuit interconnect, simultaneously and independently. As a result, STARNET carries diverse types of traffic i.e. bursty and continuous, low-speed and broadband in an efficient way. Each node requires only two lasers and its structure permits frequency stabilization of the whole network. An experimental 4-node, 12Gbits 3Gbits per node, FDDI-compatible at the packet network level STARNET is being built at Stanford University. Each node of the network is optically connected to a passive optical star. Each node is also equipped with a fixed frequency transmitter which is assigned a unique frequency, so that a comb of optical carriers is formed. Transmitters multiplex two independent data streams on the same optical carrier, the C circuit stream and the P packet stream, using non-interfering modulation formats, DPSK and low- modulation-index ASK, respectively.
