7db 10 db lc/upc fiber optic attenuator
Fiber Optic 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.
Features:
1. Low back reflection and Low PDL .
2. High precision attenuation value .
3. Precision control of attenuation range .
