Problems solved by technology

However, for QSFP series optical modules, when the system board needs to quickly turn off the laser in the optical module, and / or when there is no signal on the receiving side of the optical module and needs to send a prompt signal to the system board, the relevant information is usually read through the bus operation, and in some long-distance transmission processes, there may be problems that the timing cannot meet the requirements

Abstract

The present disclosure relates to a pin multiplexing method and device, an optical module, and a communication device. The pin multiplexing method is applied to an optical module, wherein the optical module includes a preset register, a first pin, and a second pin. It is characterized in that the pin multiplexing method includes: obtaining the pin information in the preset register and analyzing the pin information; when it is analyzed that the pin information contains the first information, the The first pin is configured to have the function of LPMODE and the second pin is configured to have the function of Intl; when it is analyzed that the pin information contains the second information, the first pin is configured to have the Disable the function and configure the second pin to have the Loss function. The disclosure enables the same pin of the optical module to have different functions in different scenarios, so as to meet the requirement of multiplexing.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular, to a pin multiplexing method and device, an optical module, and communication equipment. Background technique [0002] In the field of communication technology, in order to meet the market demand for higher-density high-speed pluggable solutions, QSFP (Quad Small Form-factor Pluggable, four-channel small form-factor pluggable, hot-swappable) series of optical modules emerged as the times require. [0003] Due to its good power consumption and high information transmission rate, QSFP series optical modules can be widely used in data centers, high-speed computers and other scenarios. However, for QSFP series optical modules, when the system board needs to quickly turn off the laser in the optical module, and / or when there is no signal on the receiving side of the optical module and needs to send a prompt signal to the system board, the relevant information is usual...
