1550nm PM Band Pass Filter(5nm)   

Description 

The 1550nm Band-pass Filter is based on thin-film filter technology that passes wavelengths within a certain range and rejects (attenuates) wavelengths outside that range. The band-pass filter features high isolation, low insertion loss, high power handling available upon request. PM (polarization maintaining) BPF available on request.
