Abstract: A retimer application system is provided, which includes a primary chip, a retimer, and a secondary chip. After first link training is completed, the retimer is configured to store, in a first storage area, an equalization parameter corresponding to each rate during the first link training, and data stored in the first storage area is not lost when the retimer performs a reset operation. The retimer is further configured to: receive a reset indication, and perform the reset operation according to the reset indication. The primary chip and the secondary chip are configured to perform second link training triggered by the reset indication. During the second link training, the retimer is further configured to: invoke the equalization parameter, and transparently transmit a training sequence in the second link training to the primary chip or the secondary chip based on the equalization parameter.

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.
