Abstract

The invention discloses an online picketage system and an online picketage method of a device of an optical communication system, and the picketage system comprises an online remote picketage controller, which is connected with a light panel unit through a main control panel of the device and used for querying an optical power value of an object port on the light panel unit through the main control panel of the device and sending a picketage command to the light panel unit through the main control panel of the device according to the optical power value; and an optical power detecting unit, which has one end connected with the light panel unit and the other end connected with the main control panel of the device, and is used for obtaining an actual optical power value of the object port and reporting the actual optical power value to the online remote picketage controller through the main control panel of the device. The online picketage system is favorable for implementing online remote restoration according to related issues in the optical power detection that are discovered in projects, improving the engineering maintenance capacity of products, and furthest protecting and raising the benefits of equipment operators and manufacturers.

Description

technical field [0001] The invention relates to a calibration technology for system equipment in the field of optical communication, in particular to an online calibration method and system for optical power detection in optical communication system equipment. Background technique [0002] Before the single board of optical communication system equipment is produced and leaves the factory, it is necessary to calibrate the optical power of the single board, especially the optical board, such as the optical multiplexer board, the optical demultiplexer board, the optical protection board, the optical amplifier board, and the optical forwarding board. Ensure that the optical power performance value of these types of boards is accurately detected during engineering use (that is, the error between the optical power value reported to the network management by the board and the measured value obtained by the optical power meter must meet the requirements, if the error is less than 1...

AI Technical Summary

Problems solved by technology

[0009] In the above process, there are some problems in the use of equipment and in the mass production process: for example, some uncertain factors in the calibration process of equipment in mass production; during the long-term continuous operation of equipment, external environmental factors will affect the adverse effects on the A / D acquisition related parts in the system; the data of the calibration coefficient of the single board is lost or rewritten abnormally, etc. These factors will cause the optical boards in the system to have a large optical power performance value when detecting and reporting to the network management system Deviation faults, these faults may have a fatal impact in the process of product engineering operation, such as abnormal switching, abnormal laser pump shut down leading to business interruption, abnormal alarm, abnormal system power control, etc.
