Abstract: This application provides a data communications system and method. The system includes a first chassis and a second chassis. The first chassis includes a first high-performance switching module and a first low-performance switching module. The second chassis includes a second high-performance switching module and a second low-performance switching module. The first high-performance switching module is connected to the second low-performance switching module. The first low-performance switching module is connected to the second high-performance switching module. The first high-performance switching module is configured to connect to a third low-performance switching module in a third chassis that is to be added to the communications system. The second high-performance switching module is configured to connect to a fourth low-performance switching module in the third chassis that is to be added to the communications system. During capacity expansion, there is no need to change cables between deployed chassis.

Abstract: An optical communication system includes a first component, a second component, and an optical connection assembly that connects the first component and the second component. An example method includes: controlling the first component to send a first optical signal to the second component through the optical connection assembly; sending an alarm indication when it is determined, based on an optical power variation status of the first optical signal in a transmission process, that the optical connection assembly is exceptional; and when it is determined, based on the optical power variation status of the first optical signal in the transmission process, that the optical connection assembly is normal, controlling the first component to send a second optical signal to the second component, where an optical power of the second optical signal is greater than an optical power of the first optical signal.
