Product Introduction
Plug-in type fixed attenuator is attached to a connector at one end and connects an adapter at the other end lts attenuation is fixed, unadjustable.
This fixed attenuator is mainly used to reduce optical power to target value in optical links lt comes in different types including SC,LC,FC,ST and MU Based on the shape of ferrule shape it can also be classified as PC and APC with 8 degrees type The products attenuation is in range of 1 to 30dB,which are all applicable for optical signal with wavelength ranging from 1,250nm to1,600nm.
