A method and system for debugging performance parameters of an optical module

Abstract

The invention discloses an optical module performance parameter debugging method and system. The method comprises the following steps: when at least one performance parameter of an optical module is debugged, grouping set values of same registers corresponding to same types of performance parameters of a plurality of optical modules with same material numbers according to the type of the performance parameter; when the quantity of the set values in each group achieves a predetermined threshold value, carrying out statistical calculation on all the set values in the group to obtain a preliminary set value, wherein all the set values in each group satisfy a normal distribution rule; and when corresponding performance parameter debugging is carried out on the next optical module, directly writing the calculated preliminary set value into a corresponding register in the optical module, reading corresponding performance parameters of the optical module during the work through an instrument, and if the values of the performance parameters read by the instrument satisfy the numerical value or numerical value range required by optical module design, completing the debugging of the next optical module. According to the method and system disclosed in the invention, the debugging time is saved and the optical module production efficiency is improved.

Description

technical field [0001] The invention relates to the field of optical module testing, in particular to a method and system for debugging performance parameters of an optical module. Background technique [0002] The basic debugging method of the performance parameters of the optical module (such as optical power, extinction ratio, etc.) is to set an initial value in the register corresponding to the performance parameter in the optical module, and then read the performance of the optical module through an external instrument. The value of the parameter is repeated until the value of the performance parameter read by the external instrument meets the SPEC requirement, that is, the value or value range required by the optical module design, that is, the debugging of the new energy parameter is completed. [0003] The current debugging methods of optical module performance parameters generally include the step method and the dichotomy method. The details are as follows: [0004...

Problems solved by technology

[0006] The inventor found that in the optical module production process, the internal device performance of multiple optical modules of the same batch (that is, the same material number) satisfies the normal distribution law. Since the device performance in the optical module satisfies the normal distribution, Then the setting value of the debugging register corresponding to the performance parameter of the optical module that meets the SPEC also satisfies the normal distribution. In this case, when debugging the performance parameters of multiple optical modules with the same material number, if the above method is still used It will increase the debugging time and reduce the production efficiency of optical modules
