Abstract

An optical time division multiplexing (OTDM) router, using a highly scalable time slot tuner, is discussed. Channel access in OTDM networks is achieved by using time slot tuners and all-optical demultiplexers. Timing precision of <1 ps is required to tune, multiplex, and demultiplex individual channels within the OTDM frame. An error-free 100 Gbit/s broadcast star architecture that can be used as the backplane for this router is presented. The router scalability based on the time slot tuner is analyzed and shows that the architecture can offer 1 Tbit/s aggregate bandwidth and support over 1000 nodes. This represents an order of magnitude improvement over current state-of-the-art electronic routers.
