Abstract
Systems and methods for resolving control conflicts in trunk protection links are provided. A head-end node includes a first line-mux controller and a second line-mux controller, first actuator components for a first fiber span, and second actuator components for a second fiber span, wherein the first line-mux controller and the second line-mux controller are configured to control the first actuator components and the second actuator components, respectively, and a trunk protection switch configured to connect an input to each of the first fiber span and the second fiber span.

A head-end node comprising:
- a first line-mux controller and a second line-mux controller,
- first actuator components for a first fiber span, and second actuator components for a second fiber span, wherein the first line-mux controller and the second line-mux controller are configured to control the first actuator components and the second actuator components, respectively, and
- a trunk protection configured to connect an input to each of the first fiber span and the second fiber span, wherein the first actuator components and the second actuator components are located at the head-end node, between the trunk protection and each of the first fiber span and the second fiber span, wherein the trunk protection is configured to interface same optical signals over either of the first fiber span and the second fiber span, and the first fiber span and the second fiber span have different configurations from one another where the different configurations cause adjustment of the same optical signals for any of gain, shape, tilt, power, and a combination thereof for each of the first fiber span and the second fiber span, respectively.
A tail-end node comprising:
- a first line-demux controller and a second line-demux controller,
- first receive actuator components for a first fiber span, and second receive actuator components for a second fiber span, wherein the first line-demux controller and the second line-demux controller are configured to control the first actuator receive components and the second receive actuator components, respectively, and
- a receive trunk protection switch configured to connect an input from each of the first fiber span and the second fiber span to an output, wherein the first receive actuator components and the second receive actuator components are located at the tail-end node, between the receive trunk protection and each of the first fiber span and the second fiber span, wherein the trunk protection is configured to interface same optical signals over either of the first fiber span and the second fiber span, and the first fiber span and the second fiber span have different configurations from one another where the different configurations cause adjustment of the same optical signals for any of gain, shape, tilt, power, and a combination thereof for each of the first fiber span and the second fiber span, respectively.
