Polarization Maintaining Filter Splitter Module (1×N) (PMFSM Series)

The PMFSM series is manufactured by using advanced technology to allow the input signal to be splitted into multi channels at a given splitting ratio while maintaining the polarization of the signal. It is characterized with low insertion loss, high return loss, high extinction ratio and excellent environmental stability and reliability. There are two type of working axis, one is both axis working and another is Fast axis blocked.


Key Features:

*Low insertion loss

*High extinction ratio

*Excellent stability and reliability 


Applications:

*Fiber lasers

*Fiber amplifiers 

*Fiber Sensors 

*Optical Communications
