System control of repeatered optical communications system

摘要

The system-level control of a repeatered optical communications system. In a repeatered optical communications system, two terminals are optically coupled via an optical communications span having one or more repeaters. One of the terminals may perform the control by monitoring quality metrics of optical signals received over the communication span. Based on this monitoring, certain adjustments are determined to be performed, and the repeater controllers of the respective optical repeaters are instructed to perform the adjustments. In some case, the optical repeater adjustments cannot be made without impacting the performance of the optical signals traveling in the opposite direction. In that case, the system-level control uses monitored quality metrics from both terminals to determine the adjustments to be made. The system level adjustment may be automated by software or the like thereby making optimization of the optical communications span easier.

主权项

1. A computer program product comprising one or more computer-readable storage media having thereon computer-executable instructions that are structured such that, when executed by one or more processors of a computing system, cause the computing system to perform a method for controlling a repeatered optical communications system having an optical communication span optically coupling a first terminal and a second terminal via a plurality of optical repeaters, the method comprising:
an act of monitoring quality metrics of at least some of the plurality of optical signals received from the optical communications span from the second terminal; an act of determining an adjustment to be made in the performance of a first of the plurality of optical repeaters using at least the monitored quality metrics obtained during a first period; in response to the act of determining the adjustment to be made in the performance of the first of the plurality of optical repeaters using at least the monitored quality metrics obtained during the first period, an act of causing an instruction to perform the determined adjustment to be dispatched to a repeater controller of the first of the plurality of optical repeaters; an act of determining an adjustment to be made in the performance of a second of the plurality of optical repeaters using at least the monitored quality metrics a second period; and in response to the act of determining the adjustment to be made in the performance of the second of the plurality of optical repeaters, an act of causing an instruction to perform the determined adjustment to be dispatched to a repeater controller of the second of the plurality of optical repeaters.
