Abstract
An all-optical network comprises: a first network; a second network; and a PWXC coupling the first network to the second network and comprising passive optical components. A method comprises: receiving a first optical signal from a first tail node of a first network; directing the first optical signal from a first input port of a PWXC to a first output port of the PWXC using first passive optical components; and transmitting the first optical signal to a third head node of a third network. An all-optical network comprising: a light bank; a first network coupled to the light bank; a second network coupled to the light bank; and a first PWXC coupling the first network and the second network.
