Abstract:
1. A method comprising: providing, in an optical node in an optical network, a test configuration for routing a test signal, transmitted from a test component of the optical node, over a primary optical fiber; performing, using the test signal and the test configuration, testing associated with an optical path through the optical node, to identify one or more faults associated with the optical path; sending, via an optical service channel carried on the primary optical fiber, one or more messages including information regarding the identified one or more faults to a remote device in the optical network; receiving, responsive to the one or more messages and via the optical service channel, one or more instructions issued from the remote device to address the identified one or more faults; and addressing, using one or more components of the optical node, the identified one or more faults based on the one or more instructions, wherein when the identified one or more faults comprise a break detected in the primary optical fiber in a portion of the optical path, the addressing comprises reconfiguring one or more 1×2 optical switches in an optical amplifier module in the optical path to reroute an optical signal over a backup optical fiber in lieu of the primary optical fiber.
