Optical fiber line fault detection system and detection method

Abstract

The invention discloses an optical fiber line fault detection system and detection method. According to the optical fiber line fault detection system, a transmitting optical fiber connected with an optical module to be detected and a movable end of a receiving optical fiber are connected together so that a complete optical loop is formed; in the optical loop, the transmitting optical power of thetransmitting optical fiber and the receiving optical power of the receiving optical fiber of the optical module to be detected can be simultaneously obtained at the end of the optical module to be detected through a network management unit of the optical module to be detected. Detection personnel, optical power meters and other detection equipment do not need to be arranged at the two ends of theoptical fiber line, convenience and accuracy are high, and the personnel and equipment cost of optical fiber line fault detection is reduced while the optical fiber line fault detection efficiency isimproved.

[0003] The optical fiber line connected by the optical module is one of the important factors that determine the communication quality. In the prior art, for the fault diagnosis method of the optical fiber line, the optical power meter is usually used to measure the two ends of the optical fiber line. If the two ends of the optical fiber line are far away , it is often necessary to arrange professional and technical personnel at both ends for fault judgment, which undoubtedly reduces the efficiency of optical fiber line fault detection and increases the cost of personnel and equipment for optical fiber line fault detection
