The JDS Uniphase Attenuator Shelf holds eight attenuators and one control cassette in a low profile 19 inch rack-mounting shelf. It is ideal for controlling the optical launch conditions of DWDM system test beds. It operates over the 1200-1700 nm range with resolution of 0.05dB and provide standard 60 dB attenuation range. The inherent linear design and low polarization sensitivity allow the attenuators to be inserted directly at the output of an array of laser sources to stabilize or adjust optical power for each channel. The shelves can be stacked to provide higher channel testing capacities, such as 16, 32, and 40 channels.
Each attenuator is controlled from the front panel keypad or by the GPIB remote interface.The commands are SCPI compatible, and LabVIEW drivers simplify remote control. The individual attenuators are etalon-free for low distortion and feature low polarization dependent loss (PDL) and return loss.
