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 (304) an optical signal between the first tributary port and the second tributary port with the reflective element.

A method in an optical Wavelength Selective Switch (WSS) for multidirectional switching of optical signals, wherein the optical WSS comprises a reflective element, a first tributary port and a second tributary port, the method comprising:
- switching an optical signal between the first tributary port and the second tributary port with the reflective element,
- wherein the optical signal is input to the first tributary port and output on the second tributary port.
An optical Wavelength Selective Switch (WSS) for multidirectional switching of optical signals, wherein the optical WSS comprises a reflective element, a first tributary port and a second tributary port, the optical WSS is configured to:
- switch an optical signal between the first tributary port and the second tributary port with the reflective element,
- wherein the optical signal is input to the first tributary port and output on the second tributary port.
An optical network node for multidirectional switching of optical signals in a communications network, the optical network node comprising one or more optical WSSs, wherein the optical WSSs each comprise a reflective element, a first tributary port and a second tributary port and each are configured to:
- switch an optical signal between the first tributary port and the second tributary port with the reflective element,
- wherein the optical signal is input to the first tributary port and output on the second tributary port.
