Test system and test method for optical module with OAM function

Abstract

The invention relates to a test system and test method for an optical module with an OAM function, and the system comprises a reference optical assembly which transmits a mixed optical signal, and the mixed optical signal comprises a 25G main business optical signal and an OAM optical signal which is transmitted according to OAM modulation information and carries specified wavelength information; the to-be-tested optical module is used for receiving the mixed optical signal and identifying wavelength information of the OAM optical signal; and the control assembly is used for determining whether the to-be-tested optical module is qualified or not according to the identification result, the OAM modulation information is information generated by the control assembly according to the corresponding relation between the serial number of the to-be-tested optical module and the wavelength information of the OAM optical signal, and the reference optical assembly receives the OAM modulation information and stores the OAM modulation information in a specified bit position of a data exchange area of the reference optical assembly. The test system can effectively solve the problem that each manufacturer cannot test the wavelength information of the OAM optical signals, achieves the effects of consistent judgment standards and interconnection and intercommunication, and can improve the production efficiency exponentially.

Description

technical field [0001] The invention relates to the technical field of optical communication testing, in particular to a testing system and testing method of an optical module with an OAM function. Background technique [0002] At present, major domestic operators are actively promoting the 5G fronthaul network based on the semi-active optical network architecture. The 12-wave color optical module with OAM (Operation Administration and Maintenance) function has become a hot spot. According to the requirements of the existing agreement , the transmitter (TX) of this type of optical module contains two major functional modules, namely the conventional 25G main service function module, which is responsible for the transmission of 25G main service optical signals, and the other is the OAM signal transmission function module, which is used to transmit a low-frequency OAM optical signal (wavelength information of OAM optical signal is one of its components), these two optical sign...

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
