Description

technical field [0001] The invention relates to the field of wavelength division equipment, in particular to an optical module fault diagnosis system and method. Background technique [0002] With the rapid growth of users' demand for optical module links, cloud computing, mobile broadband and IPTV users' requirements for bandwidth are also increasing. In recent years, 100G and above optical modules have developed rapidly in the data center market, gradually replacing the existing 40G links. [0003] However, in practical applications, the fault diagnosis and analysis of optical modules with a rate of 100G and above are difficult to solve related problems in practical applications due to the following difficulties: [0004] 1. The internal space of the optical module with a rate of 100G and above is tight, coupled with the power consumption limitation, the storage space of the optical module is limited, and the storage device that can be written repeatedly is lacking, which...

AI Technical Summary

Problems solved by technology

[0003] However, in practical applications, the fault diagnosis and analysis of optical modules with a rate of 100G and above are difficult to solve related problems in practical applications due to the following difficulties:

[0004] 1. The internal space of the optical module with a rate of 100G and above is tight, coupled with the power consumption limitation, the storage space of the optical module is limited, and the storage device that can be written repeatedly is lacking, which greatly affects the data collection of the optical module during operation. There is not enough data to analyze the fault, so the fault diagnosis cannot be completed effectively;

[0005] 2. Due to the limitation of the external hardware interface of the optical module with a rate of 100G and above (only the MDIO communication interface is external), it is impossible to effectively monitor the internal operation status of the optical module after the optical module leaves the laboratory commissioning environment

Although external devices can obtain information such as the alarm performance of optical modules with a rate of 100G and above in accordance with the standard MSA protocol "CFP MSA Management Interface Specification Version 2.0r09", these information are general information, and the amount of information is limited, so it is impossible to fully feed back the optical module The running status of each internal component cannot report different customized content for different hardware and software architectures;

[0006] 3. Most of the content collected through the MSA protocol is current real-time information, and it is impossible to query the information that has occurred in the past, resulting in some faults with a short duration. Once the fault phenomenon disappears, there is no means to check the state of the fault make inquiries;

[0007] 4. There is a lack of remote fault location means for optical modules with a rate of 100G and above. The current fault location requires debuggers to conduct information inquiries on the project site, and sometimes it is even necessary to remove the optical module from the WDM device with a rate of 100G and above. Only when it is placed on the commissioning platform can the fault be queried and located, which greatly affects the work efficiency
