LC UPC Fiber Optical Attenuator
These fiber optic attenuators consist of a male LC/UPC connector on one end and a female LC/UPC connector on the other end. When a cable end in inserted into the female end, the remaining male end can be connected to the equipment where the cable would otherwise connect directly, but providing the desired signal strength reduction. This attenuator is available in many dB attenuation values between 1dB and 30dB.
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.
