Embodiment 1

[0033] The purpose of this embodiment is to provide a method for preventing optical fiber misconnection in a wavelength division optical transmission system, so that when there is an inconsistency with the planned channel in the system, it can be detected in time and an alarm can be generated without requiring Testers carry out manual testing through test instruments one by one, with better test efficiency and accuracy and lower test cost.

[0034] When connecting physical optical fibers between network elements within a network element, it is generally connected according to the channel planning diagram, and some particularly obvious connection errors can be easily detected during the connection process, for example, on the circuit board If the optical fibers at the receiving and sending ends are reversed, the network management server will report an input irrelevant alarm. However, some connection errors are not detected by the network management server. For example, when th...

Embodiment 2

[0064] This embodiment provides a network management server, see Figure 5 shown, including:

[0065] The path determination module 51 is configured to determine the transmission path of services between network elements according to the channel planning diagram, and perform fiber connection according to the channel planning diagram when performing physical optical fiber connections between the network elements.

[0066] In this embodiment, the formulation of the channel planning diagram may adopt any existing manner. The path determination module 51 performs the fiber connection operation between the network elements of the WDM device and between network elements on the network management server according to the channel planning diagram, and can use the end-to-end search service mode to perform fiber connection processing, which will not be repeated here.

[0067] The test processing module 52 is used to generate a test verification code and send it to the corresponding serv...

Embodiment 3

[0080] In order to better understand the present invention, this embodiment further exemplifies the present invention in conjunction with a specific application scenario.

[0081] see Figure 7 In the shown networking, some boards in the network elements that do not affect the description of the solution of the present invention are omitted in the figure. Figure 7 The sending-end network element includes a first optical conversion unit, an optical multiplexer, and a first optical fiber amplifier connected in sequence; the sending-end network element includes a second optical fiber amplifier, an optical splitter, and a second optical conversion unit connected in sequence. Assuming that the service starts from the first optical conversion unit, the original plan is to perform multiplexing and demultiplexing transmission as the first wave and the second wave of the 80-wave system. First, the light emitted by the first optical conversion unit will be connected to the optical mul...

Abstract

The embodiment of the invention provides an optical fiber connection detection method, a network management server, and a receiving end network element. The method comprises the steps: determining a transmission path of a business between network elements according to a channel planning map after the physical fibers in the network elements and between the network elements are connected according to the channel planning map; generating a test verification code, transmitting the test verification code to a corresponding business receiving port on a receiving end network element on the transmission path through a corresponding business transmitting port on a transmitting end network element on the determined transmission path, and enabling the test verification code to be configured at the business receiving port; extracting an actual verification code, transmitted by the business transmitting port of the transmitting end network element to the business receiving end port, at the networkreceiving end, and carrying out the matching of the actual verification code with the test verification code configured at the business receiving port: determining that the physical fiber of the business path has a connection problem when the actual verification code is not matched with the test verification code, and automatically giving an alarm. The method enables a tester not to carry out themanual testing in a station-by-station manner, and can greatly reduce the test time and manpower cost.

Description

technical field [0001] The invention relates to the field of wavelength division optical transmission, in particular to an optical fiber connection detection method, a network management server and a network element at a receiving end. Background technique [0002] With the continuous development of optical communication technology, DWDM systems are increasingly being used in major domestic and international operators and enterprise networks. At present, the 40-wave and 80-wave systems are used on a large scale, which means that 40 or even 80 optical fibers may be inserted into a single multiplexer / demultiplexer board when the project is opened. . [0003] At present, the testing method for optical fiber connection in engineering is mainly to use the hanging meter test after the project deployment to determine whether there is a problem with the optical fiber connection. Using the method of hanging table test requires testers to run site by site and test site by site, whic...
