Digital Optical Attenuator
DOA24082 is a programmable 8-channel 850 nm multimode digital optical attenuator featuring low insertion loss, high attenuation accuracy, and excellent repeatability.
In addition, each optical output is integrated with a high-precision optical power meter for real-time monitoring of output power.
It is designed for 8-channel parallel testing of high-speed optical modules such as 400 G / 800 G, and can also be applied in various integrated testing scenarios across optical communication, fiber CATV, and related fields — meeting diverse application requirements.
