OPTICAL INTERCONNECTION SYSTEM, NODE, OPTICAL NETWORK CONTROLLER, AND DATA TRANSMISSION METHOD

Disclosed are an optical interconnection system, a node, an optical network controller, and a data transmission method. The optical interconnection system comprises multiple nodes, at least one optical network, and at least one optical network controller. Each of the multiple nodes is used for generating a first signal and a second signal according to to-be-sent data, wherein the first signal is used for requesting a transmission link, and the second signal is used for transmitting the to-be-sent data, sending the first signal to the at least one optical network controller, and sending the second signal to the at least one optical network. The at least one optical network controller is used for determining, according to the first signal, an optical link of the to-be-sent data transmitted in the at least one optical network, and controlling an optical switch in the at least one optical network to establish the optical link. The at least one optical network is used for transmitting the second signal through the
