  • Publication number: 20250125875
    Abstract: A system can include an optical interface with a first set of lanes and a processing device operatively coupled to the optical interface. The processing device can perform the operations: responsive to an optical module coupling to a port of the optical interface, determining module information from the optical module, the module information identifying a second set of lanes of the optical module. Further operations include, determining, based on the module information, a communication mode between the optical interface and the optical module and automatically assigning, based on the communication mode, a lane of the first set of lanes to a lane of the second set of lanes.
