Abstract
A scalable multicast M×N optical switch (MCS) includes a non-scalable MCS having a plurality of (L+1)×1 selector switches east coupled at one of its L entrance ports to egress ports of the non-scalable MCS, the remaining L−1 entrance ports being coupled to an L*N upgrade ports, where M and N are integers ≧2, and L is an integer ≧1. This allows the scalable MCS to be cascaded in a daisy-chain fashion, providing scalability from the M common ports to L*M common ports. In another embodiment, the selector switches are integrated into the MCS, providing scalability of common MCS ports.
