The S22 Singlemode Latching 2x2 optical switch is a standard 2x2 configuration with 4 fiber endpoints and 2 states.  In State 1, input fiber 1 is connected to output fiber 4 and input fiber 2 is connected to output fiber 3. In State 2, input fiber 1 is connected to output fiber 3 and input fiber 2 is connected to output fiber 4. The optical path from 1 to 4 in State 1 has two optical gaps and therefore twice the insertion loss.
 
This latching version of the S22 Singlemode switch requires no steady state input power. The switch is set to state 1 or state 2 by a single pulse of 20 milliseconds or longer. Continuous current is preferable to maintain the switched state under high vibrational stress. The latching design retains its switched state during a power loss.
