A method and module for affecting controlled switching of optical signals having different modes of propagation, wherein the module being provided with at least two multi-mode ports MMPs and a plurality of single-mode ports SMPs, the method comprises: inputting at least one multimode optical signal to an MMP of said MMPs; inputting the single mode optical signals to the SMPs; performing mode processing of one or more of the single mode and multi mode optical signals within the switching module, controllably and selectively switching different optical signals inputted to different ports of the module, preferably based on received feedback related to quality information, thereby allowing switching between single mode ports, between multi-mode ports, and between single mode and multi mode ports.
