Abstract:
A first configuration of an optical node may include a set of degrees, each including an inbound wavelength selective switch (WSS) and an outbound WSS. The first configuration may include a first degree expansion including a first inbound expansion WSS and a first outbound expansion WSS. An expansion input of the first inbound expansion WSS may connect to an expansion output of a second outbound expansion WSS included in a second degree expansion of a second configuration of the optical node. An expansion output of the first outbound expansion WSS may connect to an expansion input of a second inbound expansion WSS included in the second degree expansion of the second configuration. A signal input to an inbound WSS of a given one of the set of degrees may be routed, via the first degree expansion and the second degree expansion, to any drop port included in the second configuration.
