Problems solved by technology

If the OLT sends identification information through the broadcast frame, and the terminal receives the broadcast packet to obtain the OLT information, the process of this method is relatively complicated, and the PON protocol needs to be modified. At the same time, the terminal must be able to parse the protocol, and the cost is also high.

Embodiment 1

[0041] Such as figure 1 As shown, this embodiment provides a method for detecting an OLT port of an optical line terminal, the method comprising:

[0042] Step S11: Connect the information receiver to the port to be detected;

[0043] Step S12: the network management system instructs the optical line terminal OLT to issue identification information;

[0044] Specifically, the terminal device can log in to the network management system through the Internet, and issue an instruction to self-report identification information to all or part of the OLTs under the jurisdiction of the network management system. After receiving the instruction, the OLT may send the identification information once or repeatedly within a predetermined period of time through the OLT online light generating device.

[0045] Step S13: the information receiver receives the identification information sent by the OLT through the online light generating device.

[0046] Preferably, after step S13, it also i...

Embodiment 2

[0068] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0069] Such as image 3 , 4 As shown, the terminal device takes a PAD as an example, and the information receiver and the PDA can be independent or integrated. PDA can remotely log in to the network management through wired or wireless.

[0070] Such as Figure 5 The local-end on-line optical generating device shown in the figure adds a laser of another wavelength. If the OTDR function is available, the OTDR laser can be reused. In order not to affect the pin definition of the existing optical module, the I2C interface in the optical module can be used to transmit information packets.

[0071] Such as Figure 6 The shown receiving information receiver, when working, filters out the light of the business wavelength through an optical filter, and then converts it into electrical information through a photodiode for amplification and analysi...

Abstract

The invention provides an optical line terminal OLT port detection method. The method comprises the steps that an information receiver is accessed to a port for detection; a network management system indicates an optical line terminal OLT to issue identification information; and the information receiver receives the identification information transmitted by the OLT through an online light generation device. According to the scheme, the information of the maintenance port can be rapidly known without dependence on business or modification of a PON protocol so that maintenance is enabled to be simpler and more convenient, and the maintenance efficiency can be enhanced.

Description

technical field [0001] The invention relates to the communication field, in particular to a port detection method and system. Background technique [0002] As an emerging technology, optical fiber communication has been developing rapidly and widely used in recent years, which is rare in the history of communication. It is also an important symbol of the world's new technology revolution and the main transmission tool for various information in the future information society. FTTB (Fiber to The Building, fiber to the building), FTTH (Fiber to The Home, fiber to the home) have become the best means to solve the bandwidth bottleneck problem of the access network, and the passive optical network technology with its high bandwidth, long-distance transmission And the advantages of point-to-multipoint topology are favored, and it has become the main application architecture for deploying FTTH and FTTB in various countries. PON (Passive Optical Network, Passive Optical Network) is...
