working Principle
The 1×1 PM optical switch employs a mechanical relay mechanism to toggle between two states as follows.
Its design ensures stable and precise polarization-maintaining signal transmission by transmitting light along the slow axis while minimizing interference.
Stage A
Connects Port1-Ports.
Stage B
Connects port P1 to port P3.
