Optical module access method, apparatus and system, electronic device, and nonvolatile readable storage medium

An optical module access method, applied to an optical module access system, wherein the optical module access system comprises a processor and an interface function extension structure;

• the interface function extension structure comprises a plurality of controllers, and the processor is connected with a port of each of the plurality of controllers via a target bus;
• the processor is configured to issue an optical module access request to the interface function extension structure via the target bus;
• and
• each of the plurality of controllers of the interface function extension structure is connected with a plurality of optical modules via a plurality of Inter-Integrated Circuit (I2C) buses, and is configured to access a target optical module according to an optical module address carried in the optical module access request, and to perform information feedback to the processor by means of interrupt multiplexing;
• and the optical module access method comprises:
• receiving an optical module access request;
• and
• accessing a target optical module according to an optical module address carried in the optical module access request, and performing information feedback by means of interrupt multiplexing.
