A method and a device for optical switching are disclosed. The method includes: receiving input optical signals; switching the input optical signals to an optical grouping unit when the input optical signals need to be grouped, and then receiving grouped optical signals; and switching the grouped optical signals to corresponding output ports for outputting. The device includes an optical switching unit and an optical grouping unit. A part of output ports of the optical switching unit are connected to input ports of the optical grouping unit, and output ports of the optical grouping unit are connected to input ports of the optical switching unit. The optical switching unit is configured to control transmission paths of the optical signals, and the optical grouping unit is configured to group the optical signals.
