Method and system for detecting faults of composite optical fiber communication line

Abstract

The invention discloses a system for detecting faults of a composite optical fiber communication line in the technical field of detection of optical fiber faults. The system comprises an optical fiber signal acquisition subsystem, the optical fiber signal acquisition subsystem is separately in electric output connection with a position information acquisition subsystem, a power detection subsystem and a closed circuit and open circuit detection subsystem, the position information acquisition subsystem, the power detection subsystem and the closed circuit and open circuit detection subsystem are in electric output connection with a central processor, and the central processor is separately in electric output connection with a storage unit, an alarm subsystem and a cloud uploading subsystem. According to the system for detecting the faults of the composite optical fiber communication line, the faults are removed in a classification manner by the power detection subsystem and the closed circuit and open circuit detection subsystem, the fault information is located accurately, a close worker is reminded by the alarm subsystem, the information is transmitted to a remote worker by the cloud uploading subsystem, and thus workers within different ranges can know the situation conveniently.

Description

technical field [0001] The invention relates to the technical field of optical fiber fault detection, in particular to a composite optical fiber communication line fault detection method and system. Background technique [0002] Today, with the rapid development of network technology, network applications are gradually becoming popular, such as network communication, network shopping, and network entertainment, which have become a part of modern people's life. The existing access network copper wire system is far from meeting the demand for high speed and broadband. The Passive Optical Network (PON) is a broadband and high-speed, environmentally friendly and energy-saving broadband access technology, and is the best candidate to replace the existing access network. Passive optical networks are being accepted and deployed by most operators to meet the growing demand for communication users and faster and better services. After the placement and deployment of a large number o...
