Optical splitter remote control method and system

Abstract

The disclosure provides a remote control method and system for an optical splitter, which relate to the field of data communication. The method includes: after the integrated network management system determines the abnormal optical network unit, the isolation control server sends an instruction to close the optical path of the abnormal optical network unit to the isolation device, wherein the isolation device is set between each optical network unit and the corresponding optical splitter ; The isolation device isolates the connection between the abnormal optical network unit and the optical splitter according to the optical path instruction. The disclosure realizes the isolation of physical lines between the abnormal optical network unit and the normal optical network unit, can effectively distinguish the abnormal optical network unit from the normal optical network unit, and reduces service failures.

Description

technical field [0001] The present disclosure relates to the field of data communication, in particular to a remote control method and system for an optical splitter. Background technique [0002] The optical splitter is a passive device, located between the OLT (Optical Line Terminal, Optical Line Terminal) and the ONU (Optical Network Unit, Optical Network Unit) connected through optical fibers to form a passive optical network. [0003] Passive optical network is a point-to-multipoint, single-fiber bidirectional transmission network. Due to the long-term use of the ONU on the user side, the optical devices are prone to aging or hardware failures, resulting in the lasers of individual ONUs not performing burst light strictly according to the time slots allocated by the OLT, and hanging on the same PON (Passive Optical Network , passive optical network) port, and all users under the same optical splitter cause service failures. The industry calls this kind of long-emitting...

AI Technical Summary

Problems solved by technology

Because the ONU is out of control or hardware failure, maintenance personnel can only be arranged to come to replace the faulty ONU. If the user is not at home, the maintenance personnel can only go to the optical splitter in the corridor to plug and unplug the optical fiber one by one to determine which optical fiber is connected to the rogue. ONU, causing a lot of manpower and material resources to be spent on troubleshooting
