    Abstract: An optically-addressable optical switch is disclosed. The optically-addressable optical switch receives, using an optical input, a first optical signal or portion of an optical signal and determines, based on the received optical signal, an address of an optical connector. The address is one of a plurality of addresses respectively corresponding to a plurality of optical connections of the optical switch. The optical switch subsequently receives a second optical signal or portion of an optical signal, using the same optical input, and outputs the second optical signal or portion of the optical signal to the optical connection corresponding to the determined address.
