First Claim
1. A method comprising:
- detecting, by a multi-lane optical transceiver, an optical interruption event corresponding to an optical lane within a multi-lane optical path, wherein the multi-lane optical path comprises the optical lane corresponding to the optical interruption event and a plurality of optical lanes that do not correspond to the optical interruption event;
instantiating, by the multi-lane optical transceiver, an optical protocol alarm based on the optical interruption event;
generating, by the multi-lane optical transceiver, an optical protocol message based on the optical protocol alarm; and
instructing, by the multi-lane optical transceiver via the optical protocol message, a peer multi-lane optical transceiver to alter optical transmission along the multi-lane optical path bythrottling bandwidth of the multi-lane optical path to below a bandwidth minimum threshold while maintaining connection along the multi-lane optical path by routing data through the plurality of optical lanes that do not correspond with the optical interruption event,maintaining power to an optical transmitter corresponding to the optical lane that corresponds with the optical interruption event while not routing data through the optical lane corresponding with the optical interruption event so as to determine whether the optical interruption event is occurring due to the optical transmitter or due to the optical lane corresponding with the optical interruption event within the multi-lane optical path, androuting power to a reserve optical transmitter to activate the reserve optical transmitter so as to provide optical transmission along a reserve optical lane using a wavelength that was associated with the optical lane corresponding with the optical interruption event.

Abstract
Concepts and technologies for multi-lane optical transport network recovery are provided herein. In an embodiment, a system includes a multi-lane optical transceiver. The multi-lane optical transceiver can include a transmitter optical sub-assembly, a receiver optical sub-assembly, and a controller that includes a processor and a memory that stores computer-executable instructions that, in response to execution by the processor, cause the processor to perform operations. The operations can include detecting an optical interruption event corresponding to an optical lane within a multi-lane optical path. The operations can further include instantiating an optical protocol alarm based on the optical interruption event. The operations can further include generating an optical protocol message based on the optical protocol alarm. The operations can further include instructing a peer multi-lane optical transceiver to alter optical transmission along the multi-lane optical path based on the optical protocol message.
