A method for accurately finding and locating rogue optical cats and updating their systems

Abstract

The invention discloses a method for accurately searching and locating the position of a rogue optical modem and updating a system thereof. A system apparatus (installation and maintenance application) is researched and developed to search and locate the rogue optical modem, and a specific installation address of the rogue optical modem is provided. The method disclosed by the invention has the beneficial effects that various rogue optical modems can be quickly searched, broadband accounts, installation addresses, OLT device node machine codes, OLT device IP addresses, machine frame numbers, board numbers, PON port numbers, first stage optical splitter codes, ONUID codes, SN codes, MAC address codes, LOID codes and other related information of the rogue optical modems can be associated accurately, the installation and maintenance application researched and developed according to the method can quickly search and locate the rogue optical modems and can upgrade low-version rogue optical modems to improve the troubleshooting efficiency and reduce the network fault rate.

Description

technical field [0001] The invention relates to the technical field of searching various rogue optical modems in an optical network. Specifically, the invention relates to a positioning method for accurately finding the specific positions of various types of rogue optical modems based on the existing access network management. Background technique [0002] In addition to the currently known long-emitting rogue optical cats, there are also a large number of other types of rogue optical cats found in the actual optical network, including: irregular light rogue optical cats, low-version mutually exclusive rogue optical cats, anonymous Rogue optical modem, self-loop rogue optical modem, address drifting rogue optical modem, etc. [0003] With the maturity of optical fiber access technology and the rapid advancement of "optical access and copper exit", there is a technical problem affecting the installation and maintenance work under the FTTH optical network: as long as there are...

Problems solved by technology

[0003] With the maturity of optical fiber access technology and the rapid advancement of "optical access and copper exit", there is a technical problem affecting the installation and maintenance work under the FTTH optical network: as long as there are rogue optical modems (faulty PON uplink home gateways) on the optical network It will cause other optical modems under the same PON port in the OLT equipment to frequently drop or go offline, so that the 64 FTTH users carried by the entire PON port cannot make calls, broadband Internet access and watch IPTV. The method is relatively primitive. Each time, it is necessary to repeatedly pull out the optical fiber at the first-level OBD (optical splitter) and the second-level OBD to determine the specific location of the rogue optical cat and replace it. The entire troubleshooting takes a long time, such as figure 2 As shown, it seriously affects the perception of FTTH users, and this problem needs to be solved urgently

[0004] However, the traditional detection based on optical network unit and self-closing light source processing method can only diagnose and deal with the light source of "long-emitting and irregular light-emitting" rogue optical cats. It is necessary to replace hardware such as the optical modem light-emitting module or replace the optical modem, which will cost a lot of money
