PM Optical Attenuators

PM Optical Attenuators (Polarization Maintaining Optical Attenuators) are devices used in optical systems to regulate the intensity of an optical signal while maintaining its polarization. They combine the functions of polarization maintenance technology and optical attenuators to enable precise control and management of polarized optical signals in optical systems.

In fiber optic communication systems, regulating the intensity of optical signals is an important task to ensure the stability and reliability of optical signals during transmission and processing in the system. The polarization-maintaining optical attenuator is capable of regulating the intensity of the optical signal while keeping the polarization state of the output optical signal unchanged.
