These connectorized couplers are free of fiber pigtails and ready to be inserted in optical systems without the headaches of tinkering with fragile and messy fiber pigtails.

This device can be used either as a polarization beam combiner to combine light beams from two PM input fibers into a single output fiber, or as a polarization beamsplitter to split light from an input fiber into two output fibers of orthogonal polarization states.
