Embodiment Construction

[0051] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0052] see image 3 , a BOSA automatic calibration system based on GPON routers, the specific process is as follows:

[0053] (1) The actual value of the luminescence parameter read by the tester is submitted to the calibration software in the computer;

[0054] (2) The calibration software checks whether the actual value of this parameter is within the expected threshold range;

[0055] (3) If the actual value of this parameter is not within the expected threshold range, the calibration software resets the relevant registers of the BOSA chip and jumps to step (1);

[0056] (4) If the actual value of this parameter is within the expected threshold range, the BOSA calibration storage system continues to set other registers of the BOSA chip; for example, a BOSA chip needs to set its lookup table, which contains a total of 105 registers, and the BOS...

Abstract

The invention discloses a BOSA automatic calibration and data storage system based on a GPON router. For a calibration process, a part of processes needing to be participated by calibration software are completed by a BOSA calibration storage system, the number of times of interaction between the calibration software and a BOSA chip is reduced, and the overall calibration efficiency is improved; and for a calibration data storage reload part, the calibration data is subjected to double storage, thereby guaranteeing that when one part of the calibration data is damaged due to abnormity, the system can also load correct data, and the stability and robustness of the system are improved. The BOSA automatic calibration and data storage system integrates a plurality of BOSA chip initialization processes of different, reads the product information of the BOSA chip when the system is started, and automatically selects the corresponding BOSA initialization process according to the product information of the BOSA; therefore, the trouble that the initialization program needs to be synchronously updated due to the fact that the BOSA chip is replaced is avoided, the compatibility and the self-adaptability of the system are improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a BOSA automatic calibration and data storage system based on a GPON router. Background technique [0002] With the rapid development of network communication technology, optical communication technology has been widely used in various routers, among which the optical transceiver module BOSA (Bidirectional Optical Sub-Assemblies) is an important part of the optical communication terminal. In order to ensure the quality of products, each product needs to be BOSA calibration test before leaving the factory. [0003] The existing calibration method is to adjust the parameter value of the relevant register in the BOSA chip through the calibration software on the computer. The tester obtains the latest actual value of the luminescence parameter and sends it to the calibration software. The calibration software checks the new actual value of the luminescence parameter. ,...
