2x2 PM Fiber Couplers/Taps

Thorlabs’ 2x2 PM fused fiber optic couplers, also known as taps, allow a single fiber input to be split into 2 outputs or vice versa. The panda-style polarization-maintaining fiber used in these couplers allows them to provide a high extinction ratio for light launched into the slow axis of the fiber. Couplers are available with several center wavelengths; options are shown below.
