Test system and test method of optical module with oam function

Abstract

The invention relates to a test system and a test method of an optical module with OAM function. The test system includes: a reference optical component that sends out a mixed optical signal. The OAM optical signal of the wavelength information; the optical module to be tested is used to receive the mixed optical signal and identify the wavelength information of the OAM optical signal; the control component is used to determine whether the optical module to be tested is qualified according to the identification result, and the OAM modulation information is used for the control component according to The information generated by the corresponding relationship between the number of the optical module to be tested and the wavelength information of the OAM optical signal, the reference optical component receives the OAM modulation information and stores it in the specified bit position of the data exchange area of ​​the reference optical component. The test system of the present invention can effectively solve the problem that various manufacturers cannot test the wavelength information of the OAM optical signal, realize the effect of consistent judgment standards and interconnection and intercommunication, and increase production efficiency at the same time.

Description

Technical field [0001] The present invention relates to the field of optical communication testing, and more particularly to a test system and test method of an optical module having an OAM function. Background technique [0002] At present, the major domestic operators actively promote the 5G pre-transmission network based on semi-active optical network architecture, the 12-wave light module with OAM (Operation Administration and Maintenance, Operation and Maintenance Management) function, becomes a hot spot, according to existing protocol requirements Such optical module transmit terminal (TX) contains two major functional modules, that is, a conventional 25G transmitter main service module, with 25G primary traffic signal transmission, and another is an OAM signal transmitting function module for transmitting a low frequency. OAM optical signal (OAM optical signal wavelength information is one of its composition components), the two optical signals are superimposed together in...

Problems solved by technology

[0012] In this semi-active optical network architecture, according to the protocol requirements, the optical modules on the AAU side and the DU side need to identify the OAM wavelength information when they are respectively used as the receiving end. There are currently two major problems in response to this protocol requirement. The first is that the industry No instrument manufacturer has yet developed a corresponding test instrument system, that is, no benchmarking instrument system can be used. The second is the test system developed by the manufacturer involved in the development of OAM signal processing function modules. There are two common problems. One is that it is very difficult to operate. Complicated and low in production efficiency; in addition, it is even more fatal that the judgment standards of various manufacturers are inconsistent, and it is impossible to achieve interoperability between different manufacturers
