LC Fixed Attenuator, Male-Female
Optical fiber attenuator is a kind of optical passive device. It is used for optical power performance, optical fiber instrument debugging and correction in optical communication systems, attenuates the input optical fiber signal power, and prevents distortion of the optical receiver due to excessive input optical power. The product is manufactured by using attenuating fiber doped with metal ions, which can adjust the optical power to the required level; LC fixed attenuators provided by HYC have the advantages of easy installation, good interchangeability, high and low temperature resistance, etc. Used in telecom networks, CATV, data centers and other fields.
