Abstract: Disclosed are an active optical cable and a method for switching a communication mode thereof. The active optical cable comprises a first connector for being connected to a Source; a second connector for being connected to a Sink; a cable located between the first connector and the second connector and comprising a first optical fiber and a second optical fiber; and a multiplexer with one end coupled to a high-speed signal pin of the first connector or the second connector and one end coupled to the first optical fiber and the second optical fiber, and used for selecting one of the first optical fiber and the second optical fiber as a valid channel. Through the solution provided by the disclosure, signal transmission requirements in multiple use scenarios are adapted, full-function switching of USB and/or DP data of the active optical cable based on a Type-C interface is realized.
