Optical port adaptive Ethernet switch and adaptive method thereof

The invention discloses an optical port adaptive Ethernet switch and an adaptive method thereof, and relates to the technical field of communication network equipment. The Ethernet switch comprises a detection module, a control module, an Ethernet switch module and a plurality of optical port modules, wherein the detection module is connected with the optical port modules, the Ethernet switch module and the control module; the Ethernet switch module is connected with the control module and the optical port modules. During adaptation, the speed of an SFP (Small Form-Factor Pluggable) optical module is firstly read by the detection module, then the speed is acquired by the control module from the detection module, and the acquired speed is used as adaptive initial speed to perform adaptive configuration; after the configuration is finished, the configuration at the time is kept in normal work if the connection detection is successful. The connection problem in the case of non-equivalent speed is effectively solved, and the connection efficiency is high, the quality is high and the user experience is good in the adaptation process.
