PON optical communication terminal state general survey instrument

Abstract

The invention provides a PON optical communication terminal state general survey instrument. The PON optical communication terminal state general survey instrument is arranged at the rear end of an optical branching device of an optical distribution network (ODN) and is close to subscriber terminal equipment, and the PON optical communication terminal state general survey instrument comprises an optical receiving unit, an optical path distributing unit, a computing unit, a determination unit and a control unit. The PON optical communication terminal state general survey instrument provided bythe invention has the advantages that firstly the PON terminal state detection instrument according to the invention can carry out integrated network quality detection on all the circuits under a portof the branching device by being close to the rear end of the optical branching device of a subscriber without entering indoor space of the subscriber, so that high efficiency and timeliness of network maintenance are improved; and secondly, the PON terminal state detection instrument according to the invention adopts pass-type detection, and the subscriber is not influenced even if in Internet use, so that satisfaction degree of the subscriber in use is improved, and complaint rate of the subscriber is reduced.

Description

technical field [0001] The invention belongs to the technical field of detection instruments, and in particular relates to a PON optical communication terminal state survey instrument. Background technique [0002] Optical fiber cable is the communication medium of optical communication system. Compared with the copper cable medium in the past, it has obvious advantages such as low cost and high bandwidth, and has become the mainstream trend of communication system. FTTH (Fiber to the home, fiber to the home) As a new generation of broadband solutions, it is widely used and provides users with a high-bandwidth full-service access platform. It is an ideal service transparent network. [0003] In the specific implementation of FTTH, PON (Passive Optical Network: Passive Optical Network) eliminates outdoor active equipment because its ODN (Optical Fiber Distribution Network) does not contain electronic components and expensive active equipment, and the initial investment is sma...

AI Technical Summary

Problems solved by technology

[0009] The optical splitter port of the PON network is the user line resource. When an existing user withdraws due to reasons such as relocation or change of service provider, the background management system platform only cancels the user account. The part of the optical cable to the user's indoor cannot be physically revoked because the port identification cannot be performed. The reason why the port identification cannot be performed is that the user identification of the optical splitter port is unclear or missing due to reasons such as the replacement of the operator and the long use of the line.
