Abstract

The invention discloses an apparatus for automatically downloading firmware programs of optical modules in a classified manner. By utilizing the apparatus, the optical modules consisting of differentMCUs can be subjected to firmware program downloading, and the temperatures of the optical modules are calibrated. The apparatus is realized through the following technical scheme: an MCU chip U1 is connected with a dual 4:1 multiplexer chip U3 and a dual 4:1 multiplexer chip U4; firmware program downloading software in a PC sends an instruction of switching a conduction path of the dual 4:1 multiplexer chip to the MCU chip U1 through a USB; and after receiving the instruction, the MCU chip U1 judges the type of the instruction, switches the conduction path of the dual 4:1 multiplexer chip toan electric interface socket of the corresponding optical module according to a selected optical module type, and executes firmware program downloading for the optical module through a C2 bus or an I2C BUS.

Description

technical field [0001] The invention relates to a device for downloading firmware programs of different types of optical modules in the field of optical communication. Background technique [0002] In the field of optical module technology, more and more optical modules with digital diagnosis and detection functions are realized by combining a microcontroller unit MCU chip and an EML laser driver. It mainly monitors the temperature, supply voltage, bias current, received optical power, and transmitted power of the optical module with digital diagnostic detection function in real time, and judges the communication status of the optical module by analyzing the digital measurement results. And by programming the microcontroller unit MCU chip, the registers in the EML laser driver can be configured and a corresponding communication link can be established. [0003] The optical module is one of the important devices in optical fiber communication. There are many types of optical...
