FC Fixed Flange Type Optical Attenuator 3-20dB Accurate Attenuator
Flange Type Fixed Attenuator also called adapter type attenuator,the shape is similar to the common adapter.The principle is to install the attenuator inside the adapter,so that the connector is not connected with each other to achieve the purpose of attenuation.
This range of fixed attenuator is mainly used to reduce optical power to target value in optical links. It comes in different types including SC, LC, FC, ST and MU. Based on the shape of ferrule shape, the fixed optical attenuator can also be classified as PC and APC with 8 degrees type. The attenuation value is in range of 0 to 30dB, which are all applicable for optical signal with wavelength ranging from 1,250nm to 1,650nm.
