The polarization beam combiner and depolarizer is a compact, high-performance
micro-optic-based depolarizing component. It normally functions as a combiner
to combine two orthogonal-polarized pump beams together and then converts
it to a depolarized beam at the output port. Depending on special customer
requirements, the isolator functionality can be integrated with the depolarizer or
remain as a stand-alone depolarizer without combining functionality.

Ports 1 and 2: Panda PM fiber, port 3: SMF-28 fiber
Port 1: black, port 2: clear, port 3: clear
Note: Parameters are specified for the whole wavelength range and operating temperature range without a connector. The direction of linear polarization is aligned with the
slow axis of the PM fiber.
1. Extra loss from pump PER is excluded.
2. Maximum input power for each port is 1000 mW.
