Polarization Maintaining Filter Coupler Module 1550nm 1x2/2x2

Polarization Maintaining Couplers complement our CoBrite series of laser sources and allows to multiplex channels on any arbitrary grid (“FlexiGrid” feature”) while polarization of each input is preserved. Stable output polarization of all laser lines allows for arbitrary modulation of a channel comb using Mach-Zehnder structures.

Using couplers instead of complicated tunable Filter or WSS structures to generate Flexigrid scenarios offers cost savings and no effort for configuration of WSS structure while polarization preservation is delivered for free.

If high port count Polarization Maintaining Couplers are required to multiplex many channels, amplification might be required to compensate for loss incurred.

We offer Polarization Maintaining EDFAs in case the resulting output power is too low for your application while still offering great cost advantage over a WSS structure for multiplexing.
