Fiber Optical Attenuator,1dB To 30dB SC APC Fiber Optical Attenuator Male To Female Plug Type
Description of optic fiber attenuator
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.
