Optical attenuator is a passive device used to reduce the power level of an optical signal. It could be applied to debug optical power performance & optical instrument calibration correction & fiber signal attenuation to ensure the optical power in a stable and desired level in the link without any changes on its original transmission wave.
Finetelecom offers LC,FC,SC,ST and MU fixed attenuator with different attenuation level, from 1dB to 30dB.
