Abstract
A method in an optical Wavelength Selective Switch, WSS, for multidirectional switching of optical signals. The optical WSS comprises a reflective element, a first tributary port and a second tributary port. The optical WSS switches () an optical signal between the first tributary port and the second tributary port with the reflective element.
