Dual adapter interface LC attenuator

The invention relates to an optical communication device, and discloses a dual adapter interface LC attenuator. The attenuator comprises a plastic jacket and ceramic ferrules, and is characterized in that a standard LC adapter interface is separately arranged at the left and right ends of the plastic jacket, wherein a through hole is formed in the middle of the plastic jacket to communicate the two LC adapter interfaces, a metal connecting sleeve is installed in the middle of the through hole, and left and right ceramic sleeves connected with the two ends of the metal connecting sleeve are installed in the through hole; left and right ceramic ferrules are installed in the metal connecting sleeve, and attenuator fibers are arranged in the two ceramic ferrules. The attenuator effectively solves the problems of optical path signal instability and the like caused by many connecting nodes in an optical link, is mainly used for optical link connection in optical communication, and achieves the effect of fixedly att
