GaPho PM VOA Fiber Optical Attenuator Palorization Maintaining 1310nm 1550nm
Fiber Optical Attenuator Palorization Maintaining Optical Fiber VOA
The PM VOA is used to manually adjust the attenuation of laser power, so as to adjust power in a fiber optic system, and to evaluate the dynamic range of a fiber optic systems. A manual rotation knob can be used to adjust the attenuation of laser power. Multiple wavelengths (630-1550 nm) are available.
