Methods and apparatus for switching N optical input signals to M optical outputs

摘要

Apparatus and methods for switching N optical input signals to M optical outputs are disclosed. In an example, an apparatus includes a plurality of optically transparent fabrics. Each of the fabrics receive at least one optical input signal and switch that received signal to at least one of a plurality of intermediate outputs. A multiplexer is operatively coupled between the intermediate outputs of the plurality of optically transparent fabrics and the M optical outputs.
