Claim 19:
20. The second device according to claim 19, wherein:
the processor is further configured to start at the reference fiber transmission rate, and the transceiver is further configured to send a negotiation packet to the first device through the first port of the second device within a duration of the reference fiber transmission rate; and
in response to the transceiver receiving a response packet from the first device through the first port of the second device within the duration of the reference fiber transmission rate, the processor is further configured to control the first port of the second device to communicate with the first device based on an initial transmission rate, or
in response to the transceiver not receiving a response packet from the first device through the first port of the second device within the duration of the reference fiber transmission rate, the processor is further configured to perform a step of switching the fiber transmission rate of the first port of the second device to the first fiber transmission rate based on the preset switching direction within the rotation period of the second fiber transmission rate set.
