Polarization Beam Combiner/Splitter
Polarization Beam Splitter /Combiner (PBS/PBC) can be used as a polarized beam combiner (polarizing beam from two polarizing fibers to join the output of a single-mode fiber), or a polarized beam splitter (dividing the beam into two orthogonal polarization states to output into two polarizing fibers). An important application area of this device is to achieve polarization multiplexing (demultiplexing) to increase the communication capacity of optical fiber network systems.

Note:
- The PM fiber and the connector key are aligned to the slow axis.
- For devices with connectors, insertion loss will be 0.3dB higher, RL will be 5dB lower, and ER will be 2dB lower
- The above specifications are for device without connector.
