1X2 Polarization Maintaining Fiber Coupler PM1550 One-to-Two Fiber Coupler LC/APC Slow Axis
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 of the PM fiber system without changing the polarization state of the optical signal. power.
