Feeder Fiber and Central Office Redundancy

An optical network comprising:

• a first carrier office (CO) configured to transmit a first optical signal;
• a second CO configured to transmit a second optical signal, the second optical signal being the same as the first optical signal;
• a first feeder fiber optically coupled to the first CO;
• a second feeder fiber optically coupled to the second CO;
• a remote node (RN) optically coupled to the first feeder fiber and the second feeder fiber;
• and
• a controller in communication with the first and second COs, the controller configured to perform operations comprising:
• instructing the first CO to transmit the first optical signal to the RN along the first feeder fiber;
• determining whether the RN receives the first optical signal;
• and
• when the RN fails to receive the first optical signal, instructing the second CO to transmit the second optical signal to the RN along the second feeder fiber.
