PM Variable optical attenuator
Polarization Maintaining Mechanical Variable Optical Attenuator is a useful tool for the optical components and systems test. All input and output fibers are polarization maintaining to maintain the polarization state of the light. The PM Manual Variable Optical Attenuator is designed and manufactured to reduce the output optical power, get the power suitable. It is with low insertion loss, high extinction ration, high return loss and low Adjustment Precision.
