Claim 15:
16. The second device according to claim 14, wherein:
the processor is further configured to switch a fiber transmission rate of a second port of the second device to a second fiber transmission rate based on the preset switching direction within the rotation period of the second fiber transmission rate set; and
the transceiver is further configured to send a negotiation packet to a third device adjacent to the second device through the second port of the second device within a duration of the second fiber transmission rate, wherein the duration of the second fiber transmission rate is greater than or equal to a sum of a duration of all fiber transmission rates before the fiber transmission rate is switched to the second fiber transmission rate and the preset negotiation time,
wherein in response to the transceiver receiving a response packet from the third device through the second port of the second device within the duration of the second fiber transmission rate, the processor is further configured to control the second port of the second device to communicate with the third device based on the second fiber transmission rate.
