1X2 Polarization Maintaining Fiber Coupler 1310nm PM Filter Coupler FC/APC φ5.5*L35mm
The filter-type polarization-maintaining coupler uses interference-type filters to not only split the light beam from the input PM fiber into two output PM fibers, but also combine the light of two PM fibers into one PM fiber. This device can be used to separate high-power linearly polarized light into multiple channels without changing the linear polarization. It can also be used as a power splitter to monitor the signal power of the PM fiber system without changing the polarization state of the optical signal.
