Problems solved by technology

Obviously, the traditional optical module adjustment requires the debugger to be clear about the function of each adjustable potentiometer, and has high requirements for the quality of the debugger. On the other hand, the adjustment of each potentiometer inside the optical module is also very inefficient.

[0005] There are other potentiometers used for performance energy monitoring and adjustment that are not marked in the figure. Obviously, the adjustment of these mechanical potentiometers not only takes a lot of adjustment time, but also needs to clearly know the adjustment parameters corresponding to these potentiometers. In optical communication In the case of small demand in the early stage of development, the demand can be basically met

However, in recent years, with the expansion of the scale of the optical transmission network, the demand for optical modules has shown the characteristics of large one-time demand, many types of optical modules, and short delivery cycles. The production adjustment mode to manage the production of optical modules obviously cannot meet the requirements of optical communication operators. To sum up, the traditional optical module production adjustment method has the following disadvantages, including:

[0006] 1. The optical module is a technology-intensive product, which requires high quality optical module debugging technical workers, and requires a certain background knowledge of optical communication. It takes a long time to train a skilled optical module debugging technical worker

[0007] 2. The traditional optical module adjustment method is slow in adjustment speed and takes a long time, which is not suitable for the construction of sudden and large-scale optical transmission networks.

[0008] 3. Need to occupy a lot of optical module test device resources

Since there are many parameters to be monitored during the debugging of the optical module, and whether the key parameters after adjustment are accurate or not requires manual configuration of instruments to monitor, the debugging process of the optical module is bound to be accompanied by the testing process of the optical module, so it must take a long time Expensive Optical Communication Instruments

[0009] 4. Unable to realize the production management of optical modules

The traditional optical module debugging process cannot record any information about optical module debugging, so it is impossible to manage the production and debugging of batch optical modules

[0010] 5. Due to the excessive reliance on the manual debugging of skilled workers in the production of a large number of optical modules, there must be certain quality hazards. When optical modules with quality hazards are applied to the optical transmission system, it will cause major system failures, and the existence of optical modules quality defects cannot be traced

[0011] To sum up, the traditional optical module production and debugging methods can no longer meet the large-scale and sudden needs of communication operators to build optical transmission networks. Only by realizing the automatic debugging of optical modules can the adjustment speed of optical modules be accelerated and production efficiency improved. Reduce man-made quality hazards
