Demonstration of multicasting in a 100-Gb/s OTDM switched interconnect

We show that a 100-Gb/s OTDM interconnect can provide full multicasting capability using a simplified node architecture. In our demonstration, subsets of 16 channels are accessed simultaneously from a multicasting node with a setup time of 3.2 ns. This additional functionality allows the interconnect to support multicasting as well as advanced services such as single-cycle multi-channel arbitration and speed-up N mode.
