Manual Polarization Controllers

In the PLC series of polarization controllers, pressure is applied to a single-mode fiber to change its birefringence, and thus, the polarization of the output light. The user controls the amount of pressure via a thumb screw, and the pressure axis via a rotatable center section of the controller. They are available with built-in fiber or as drop-in devices that can control the polarization in fiber already in the system, Different connector configurations and sizes are also available.
