The plug-in type fixed attenuator is connected to a fiber optic connector at one end and a fiber optic adapter at the other end. Its attenuation is fixed, unadjustable.
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 1,600nm.
Our company has already established workshops to produce plug-in type fixed attenuators when we built the production base of fiber optic patch cords in 2005. We always provide fiber optic products with high quality and a competitive price to our clients at home and abroad. Customer requirements in terms of test indexes and end face controlling can be completely satisfied because we possess perfect fixed attenuator manufacturing technique.
