Abstract
A method and an apparatus for establishing a transmission path for exchanging an optical signal, where a gate device is disposed in front of an optical switch matrix, where the optical signal reaches the optical switch matrix through the gate device. A working state of the gate device and a working state of a first optical switch used for transmitting the optical signal in the optical switch matrix are adjusted in a time sequence such that when a transmission path used for transmitting the optical signal in the optical switch matrix is established, dynamic crosstalk can be reduced, and communication quality is improved.
