Abstract:
1. An optical signal control method, comprising: detecting whether a circuit board is pulled out from an optical backplane, and when detecting that the circuit board is pulled out, generating a first control instruction and transmitting the first control instruction to a transmitting port controller configured to receive the first control instruction; and if a circuit board is pulled out, querying a mapping relationship table between a transmitting port and a slot to find a transmitting port of another circuit board connected to a slot where the pulled out circuit board was located, and transmitting the first control instruction to the found transmitting port, wherein the first control instruction is used to notify of closing the transmitting port or adjusting output power of the transmitting port to make it below a preset threshold, and the preset threshold is a specified boundary value used to determine whether the transmitting port is in a working state.
