AFR is leading of polarization maintaining (PM) coupler manufacturer,we can provide you a variety of fiber laser product. For example,high power handling fiber optic components and polarization maintaining components. Today,we will tell you some features and applications of PM coupler.
The polarization maintaining (PM) coupler provides optical signal splitting with accurate tap ratio while preserving the state of polarization. By combine thin film filter technology and PM collimators, the PM coupler features low insertion loss, high return loss, high extinction ratio and environmental stable.
Features:
Ultra low insertion loss
High return loss
High extinction ratio
Accurate coupling ratio
Wide bandwidth
Environmentally stable
Applications:
Test equipment
Raman amplifier
Erbium-doped fiber amplifier
Sensor system
