Mechanical Variable Optical Attenuator

Mechanical Variable Optical Attenuators allow the user to manually vary the attenuation of the signal in the fiber as it is transmitted through the device.

Wavelength Range (nm) Attenuation Type Attenuation Range (dB)
1530 - 1570 1570 - 1610 Bright or Dark 30
1260~1620 850/1310±40 / 0.6~60/0.8~40
Insertion Loss (dB) Polarization Dependent Loss (dB)) Ripple (dB)
