PM Fiber In Line Fixed Optical Attenuator – 1dB to 20dB
Description
The 780nm Polarization Maintaining In-line Fixed Optical Attenuator utilizes fused polarization maintaining panda fiber to achieve precise attenuation value up to 30dB. Each cord is custom built length and variety of connector styles of your choice. Please select operation wavelength from 780nm to 2000nm. And 1, 2, 3, 5, 10, 15, 20, 30dB attenuation value attenuators are available.
