Description
Technical Field
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
With rapid development of network communication technology, optical communication technology has been widely applied to various routers, wherein a BOSA (Bidirectional Optical Sub-Assemblies) optical transceiver module is an important component of an optical communication terminal. In order to ensure the quality of the products, each product needs to be subjected to BOSA calibration detection before delivery.
The existing calibration method is to adjust the parameter values of the related registers in the BOSA chip through the calibration software on the computer, the tester obtains the latest actual value of the luminous parameters and sends the latest actual value of the luminous parameters to the calibration software, and if the actual value of the luminous parameters does not accord with the new actual value of the luminous parameters, the calibration software needs to be further adjusted, and the whole process is carried out in a stepping mode. In this way the number of interactions between the calibration software and the BOSA chip directly affects the final calibration time.
As shown in the automatic calibration schematic block diagram of the BOSA chip in fig. 1, the computer is connected to the ONU (Optical Network Unit) optical network unit through a con or telnet, and one end of the tester is connected to the ONU, and the other end is connected to the computer. The BOSA calibration storage system is used for serving a BOSA chip on the ONU, and calibration software on a computer sets or acquires the value of a register of the BOSA chip through the BOSA calibration storage system; the tester obtains the actual value of the BOSA luminescence parameter and feeds back to the calibration software.
The BOSA conventional calibration flow chart shown in fig. 2 is as follows:
(1) The actual value of the lighting parameter is read by the tester and submitted to the calibration software in the computer.
(2) The calibration software checks whether the actual value of this parameter is within the expected threshold range.
(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).
(4) If the actual value of this parameter is within the expected threshold range, the calibration software sets the other registers of the BOSA chip one by one in turn. For example, a BOSA chip needs to set its lookup table, which contains 105 registers in total, and the calibration software reads the relevant registers of the BOSA chip, calculates the register values of the lookup table according to a specific algorithm, and sets the calculated values to the BOSA chip.
(5) After all calibration parameters are calibrated, the calibration software sets the checksum register of the BOSA chip.
(6) The calibration data is saved.
(7) And (5) ending the calibration.
From the calibration flow, the number of interactions between the calibration software and the BOSA chip directly affects the final calibration time.
Furthermore, calibration data is lost when an abnormal situation occurs; and when the BOSA chip is replaced, the initialization program is updated synchronously, and the compatibility of the system is not too high.
