The CL Series polarization switch can quickly switch the incoming SOP between two orthogonal polarization states (SOPs). This is achieved using patented non-mechanical configurations and activated via an electrical control signal. Latching operation preserves the selected SOP after the drive signal has been removed.

The all-solid-state CL polarization fiber optic switch features low insertion loss, high extinction ratio, fast switching, and extremely high reliability and repeatability. The input is PM fiber. the output could be either PM or SM fiber. For PM fiber, the typical polarization is aligned with the slow axis.
