Abstract

The present invention relates to laser parameter file creating process in electric communication technology. It includes the following steps: detecting values corresponding to the linear relation and determining the photocurrent of photoelectronic converter and linear parameters of laser performance based on the relation between the photocurrent of photoelectronic converter in the laser and the laser performance; selecting several laser performance parameter values in linear range and calculating the corresponding photocurrent of photoelectronic converter based on the determined linear parameter to form corresponding parameter data list item between the photocurrent of photoelectronic converter and the laser performance parameter; and creating the relevant parameter file based on the obtained parameter data list item. The present invention has convenient operation, less data processing amount and less error.

Description

technical field [0001] The invention relates to electric communication technology, in particular to a method for generating a laser parameter file. Background technique [0002] In order to improve the maintainability of the product, the board needs to automatically and accurately report various performance values ​​of the laser, including: received optical power, transmitted optical power, laser bias current, etc., because the software can only read the AD of the performance parameters from the register (Analog Digital, the size of the digital signal after the analog signal is converted into a digital signal) The sample value-AD value directly reflects the size of the photocurrent, so we need to download a laser parameter file to the board, and then search and compare The value is calculated to obtain the performance value corresponding to the AD sampling value. [0003] There are two traditional algorithms for generating laser parameter files: [0004] The first method: ...
