Method and device for detecting optical fiber connection state

Abstract

The invention provides an optical fiber connection state detecting method and an optical fiber connection state detecting device and relates to the field of communication. Whether connection among network elements is right or not can be detected so as to improve online efficiency of the network elements and testing efficiency of a network. The method includes the following steps that the first network element sends a connection detecting request code stream to the second network element through a first port and the connection detecting request code stream contains a first serial number. The first network element receives a second responding code stream sent by the second network element through a second port. The second responding code stream contains a second serial number. If the first port is the same as the second port and the first serial number is the same as the second serial number, fiber connection between the first port and the port, receiving the connection detecting request code stream, of the second network element is determined to be right by the first network element.

Description

technical field [0001] The invention relates to the field of communications, in particular to a method and device for detecting an optical fiber connection state. Background technique [0002] As a mainstream way of broadband access, optical fiber has the advantages of large communication capacity, long relay distance, good confidentiality performance, and strong adaptability. Therefore, using optical fiber to access the network has become the development trend of broadband access in the future. [0003] During the construction of the optical fiber network, the staff first installs the network elements, and then performs fiber jumping on the physical links between the network elements according to the physical connection design drawings. After the construction of the optical fiber network is completed, the network Yuan goes online to work. Since each port of a network element has two optical fiber interfaces (transmitting interface and receiving interface), it often occurs ...

Problems solved by technology

[0005] However, for the above detection process, when the working modes of the optical fiber interfaces connecting the two network elements do not match, if the optical fiber interface is wrongly inserted, it may cause the optical fiber interface of the network element to be unable to open, so that the corresponding information cannot be sent and received. detection packets and test messages; when the optical fiber network has just been built, because the configuration of the network element is empty, the layer 2 protocol of the network element or the protocol above the layer 2 protocol may not be activated, so it is impossible to detect the network element The optical fiber connection between the network elements is correct, which reduces the online efficiency of the network elements and the commissioning efficiency of the network
