Abstract

Official abstract text for this publication.

The invention relates to a method for auto-configuring a wavelength selective switch (WSS) device having an output port and a plurality of input ports and coupled to a WSS controller. When connected to a WDM optical network, the WSS controller is programmed to utilize one or more optical channel monitors (OCM) coupled to the input and/or output ports to detect which of the wavelengths are present at the input ports. Wavelengths that are not detected on any input port are blocked by the WSS. Any wavelength detected as present at one and only one input port is switched by the WSS to the output port. If a wavelength is detected at two or more input ports, it is either blocked by the WSS at each of the input ports until user intervention, or is blocked at all but one of the input ports as defined by assigned port priorities.

First claim

Opening claim text (preview).

We claim: 1. A wavelength selective switch (WSS) device comprising: a WSS element having a control port, an output port and a plurality of input ports for selectively switching any of a plurality of supported wavelength from any of the input ports to the output port or for blocking thereof, a WSS controller coupled to the control port of the WSS element for controlling the switching, and one or more optical channel monitors (OCM) coupled to the input and/or output ports of the…
