Problems solved by technology

However, when the output optical power of the laser decreases due to long-term working aging, if the bias current is used to stabilize the output optical power, it will bring bad consequences
In addition, the network management and third-party systems in the industry provide alarms for board failures. Most of them are alarm prompts after failures, which are post-event alarms rather than predictions.

Description

technical field [0001] The invention belongs to the technical field of optoelectronic equipment, and in particular relates to an online failure prediction method and device for optical transmission equipment. Background technique [0002] With the increasingly wide application of optical communication technology, more and more services are undertaken by single boards of synchronous digital system (Synchronous Digital Hierarchy, SDH) network equipment, and more and more complex, sudden failure of single boards will cause business interruption or switching , affecting network stability. Therefore, its stable and reliable performance is the basis for ensuring network stability. In order to ensure the stability of the network, one of the current strategies is to stipulate mandatory updates within a certain number of years. Since the service life of each device is not completely consistent, this has resulted in many devices being replaced long before reaching the end of their li...
