1. An optical routing circuit comprising:
a first node;
a second node; and
a third node, wherein a first optical signal channel optically couples the first node to the second node, wherein a second optical signal channel optically couples the first node to the third node; and
a node control system, wherein a first node control channel electrically couples the first node to the node control system, and wherein a second node control channel electrically couples both the second node and the third node to the node control system, wherein when the second node is activated and the third node is deactivated:
control of the second node by the node control system through the second node control channel is enabled;
control of the third node by the node control system through the second node control channel is disabled; and
control of the first node by the node control system through the first node control channel is enabled such that the first node directs an optical signal to the second node through the first optical signal channel rather than to the third node through the second optical signal channel; and
wherein when the second node is activated and the third node is activated:
control of the second node and the third node by the node control system through the second node control channel is enabled; and
control of the first node by the node control system through the first node control channel is enabled such that the first node is arranged to direct an optical signal to the second node through the first optical signal channel and an optical signal to the third node through the second optical signal channel.
