COLORLESS, DIRECTIONLESS, AND GRIDLESS OPTICAL NETWORK, NODE, AND METHOD
First Claim
1. An optical node, comprising:
- an optical routing apparatus comprising N ports, wherein N is an integer greater than 2, wherein the optical routing apparatus is configured to direct light that is input to each of the N ports to all of the other N ports; and
a configurable optical blocking element located in line with at least one of the N ports.

Abstract
An optical node includes an optical routing apparatus including N ports, N is an integer greater than 2, the optical routing apparatus configured to direct light that is input to each of the N ports to all of the other N ports, and a configurable optical blocking element located in line with at least one of the N ports. A method includes broadcasting a plurality of optical signals over a plurality of ports using a broadcast element, selectively receiving a desired signal from all of the plurality of optical signals at one of the plurality of ports, and blocking the plurality of signals via a blocking element in line with one of the plurality of ports thereby preventing a multiple path of the broadcast plurality of optical signals.

22. An optical network, comprising:
-
a plurality of nodes each comprising at least one coherent optical receiver tunable across an optical spectrum; a plurality of links interconnecting the plurality of nodes, wherein optical channels in the optical network are broadcast across the plurality of links such that the optical channels reach the plurality of nodes, wherein the at least one coherent optical receiver is configured to receive a channel of the broadcast optical channels; and a plurality of configurable optical blocking elements comprising at least one configurable optical blocking element actively set on one of the plurality of links to enable the broadcast of each of the optical channels to the plurality of nodes via a single path for each of the optical channels. - View Dependent Claims (23, 24)
