Firmware upgrading method and system of optical module and optical module

Abstract

The embodiment of the invention discloses a firmware upgrading method and system of an optical module and the optical module. The optical module comprises a microprocessor and a program storage area connected with the microprocessor. When the optical module works normally, the microprocessor operates the firmware codes stored in a program storage area, and the firmware codes comprise the initialization codes and the non-initialization codes. The microprocessor firstly operates the initialization code to initialize the optical module, and then operates the non-initialization code, when an uppercomputer writes all firmware upgrading codes into the program storage area, the upper computer sends an upgrading completion notice to the microprocessor, and the microprocessor operates the upgrading non-initialization code in response to an upgrading completion notification sent by the upper computer, so that according to the technical scheme, after the firmware upgrading is completed, the microprocessor directly runs the upgrading non-initialization code, and the initialization process is not needed, and accordingly the situation that communication services are interrupted does not occur.

Description

technical field [0001] Embodiments of the present application relate to optical communication technologies. More specifically, it relates to a firmware upgrade method of an optical module, a system and an optical module. Background technique [0002] An optical transceiver integrated module, referred to as an optical module, is a standard module in equipment in the field of optical communication, used for photoelectric conversion. like figure 1 As shown, the optical module 10 is composed of an optical transmitter 102, an optical receiver 103, a single-chip microcomputer 101 and the like. Wherein, the single-chip microcomputer 101 of the optical module 10 controls the optical transmitter 102 to convert the electrical signal into an optical signal. The optical receiver 103 of the optical module 10 can receive the optical signal transmitted by the optical fiber, and convert the received optical signal into an electrical signal under the control of the single-chip microcomput...

AI Technical Summary

Problems solved by technology

When the single-chip microcomputer runs the Bootloader program, the firmware stops running, so that the optical module 10 cannot work normally, resulting in a brief interruption of the communication service
