OA5 Programmable Optical Attenuator

JGR’s OA5 Programmable Optical Attenuator enables precise optical power control and feature high accuracy and superior repeatibility.

It is ideal for lab and production applications including power level adjustment in automated test systems, BER testing of transmitters and receivers, and channel equalization in WDM systems.

The OA5 Programmable Optical Attenuator is a benchtop instrument offering dynamic range of at least 50 dB (depending on the model configuration). It can be remotely controlled via GPIB, RS232, or USB or locally via the user-friendly front panel keypad and display, simplifying the selection and confirmation of attenuation levels.
