Abstract: The present invention provides an optical signal control method, an optical signal control system and an optical backplane system, which belongs to the field of optical communications technologies. The method includes: detecting whether a circuit board is pulled out from an optical backplane; if the circuit board is pulled out, querying a transmitting port of another circuit board connected to a slot where the pulled out circuit board is located, transmitting a first control instruction to the transmitting port, and notifying of closing the transmitting port or adjusting output power of the transmitting port to make it below a preset threshold. The optical signal control system includes: a detection module and a control module. The optical backplane system includes the optical signal control system.
