VA47K+1AFP20 JDSU Optical Attenuator
The VA47K+1AFP20 is a optical attenuator from JDSU. Attenuators are a type of test equipment that’s useful during Optical design. When an engineer needs to reduce (attenuate) the level of an optical signal, he or she uses an attenuator.
- Return loss >60dB
- Very long battery life
- Portable for field use
- Optional universal connector adapter
Attenuation is set manually from the front panel at a 0.1 dB resolution. Unlike programmable attenuators, the attenuation level is maintained when the power is turned on or off. The attenuators use JDS Uniphase's ultra-linear attenuator prism and highly reliable microlense technology to produce accurate attenuation settings with low insertion loss and excellent return loss.
