OPTICAL SWITCH FOR RECIPROCAL TRAFFIC

OPTICAL SWITCH FOR RECIPROCAL TRAFFIC

A reduced component optical switch module includes a plurality of ports (28-1,28-2,28-3,28-4) wherein each port (28-1) includes an optical input and an optical output. A plurality of switchable deflectors (30a,30b,30c,32a,32b) in combination with a plurality of non-switchable deflectors (34a,34b,34c...

Zusammenfassung:A reduced component optical switch module includes a plurality of ports (28-1,28-2,28-3,28-4) wherein each port (28-1) includes an optical input and an optical output. A plurality of switchable deflectors (30a,30b,30c,32a,32b) in combination with a plurality of non-switchable deflectors (34a,34b,34c) can be used to establish transmission paths between pairs of ports to support traffic reciprocity. In one embodiment, the ports and switchable elements are configured so as to provide substantially constantly transmission paths within the respective module. In another embodiment, additional deflector elements can be provided to implement loop-back functionality at one or more of the ports.
