PM FA-MT devices in coherent transmission
Stand 569
15th September 2022

PM (Polarization Maintaining) FA-MT is used in coherent optical transmission to solve the key problem of coherent module interface. Multiple PM FAs and multiple MTs can be randomly combined in series/array. The combination can still guarantee a high extinction ratio (up to 28dB), and ultra-high pitch accuracy (0.5um). It can be widely adapted to various coherent communication modules.
