Fiber Optic
Attenuator is one kind of optical passive device which is used to debug the
performance of the optical power in the optical communication system,debugging
fiber optic instrument calibration correction, optical signal attenuation.And
used for the attenuation of the input optical power, avoid optical receiver
distortion due to input optical power powerful. The fixed fiber optic
attenuator can achieve the dual function of adapter and attenuators.
