introduction:
2x2 latching optical switch (osw) provides channel selection between a pair of input fibers and output fibers. it features low insertion loss, low driving power, small size, and high switching speed. the switch is a compact device suitable for a wide range of applications; for example, optical networking system protection, measurement system, route diversity, reconfigurable add/drop module. the latching mechanism ensures the optical switch status remains in the selected state during power failure.
