OFR Polarization Splitters divide the input (Port 1) into two oppositely polarized outputs (Ports 2 and 3).
The standard P/P/P model equally splits the input energy into the two outputs.
OFR Polarization Combiners do the reverse of the Splitters. Two oppositely polarized inputs (Port 2 and 3) are combined into a single output (Port 1). In the P/P/P model, the combined energies are coupled into both slow and fast axes of the output fiber (Port 1).

OFR Walk-OFF Polarizers in OFR Splitters separate the two polarization modes better than 55 dB. Because of near-zero absorption and absence of any optical cement, Walk-Off Polarizers are capable of handling very high powers, far beyond those in a fiber-optic system. Walk-Off Polarizers are inherently extremely broadband. AR coated, specify l .
The PM Fibers (PANDA) on all models are aligned so that the plane of polarization is parallel to the slow axis in the fiber.

1-Meter Fiber pigtails on all models can be ordered as single-mode (SM) or polarization-maintaining (PM), as designated in the Part Number. Distal end is cleaved or optionally connectorized.
