  • Publication number: 20250280217
    Abstract: Systems and methods are provided for automatically provisioning channels in an optical spectrum. A process, according to one implementation, includes a step of monitoring a Media Channel (MC) at an ingress/egress degree of an optical line system configured for operation within an optical spectrum including at least a plurality of MCs. The monitored MC has a spectral range including one or more Network Media Channels (NMCs) assigned to a customer device. Each of the one or more NMCs are provisioned as either a data-loaded signal or a noise-loaded signal. In response to detecting a change in presence of a signal within a modified NMC of the one or more NMCs, the process further includes a step of automatically re-provisioning the modified NMC within the optical spectrum to change the NMC between a data-loaded signal and a noise-loaded signal.

  • Patent number: 12047116
    Abstract: Systems and methods are provided for enhancing techniques for provisioning optical channels to allow optical networks to operate in an optimal fashion. A method, according to one implementation, includes receiving measured optical performance parameters of a plurality of optical channels transmitted over an optical spectrum between two network elements in an optical line system; determining a performance profile of the optical spectrum based on the measured optical performance parameters; translating the performance profile into configuration information for the two network elements; and causing provisioning of the two network elements based on the configuration information. The measured optical performance parameters are for one or more unassigned optical channels on the optical spectrum, with the measured optical performance parameters being made on one or more optical modems.

  • Patent number: 11695474
    Abstract: Systems and methods are provided for enhancing techniques for provisioning optical channels to allow optical networks to operate in an optimal fashion. A method, according to one implementation, includes utilizing a plurality of modems to measure optical performance parameters of a plurality of optical channels of an optical spectrum. Each optical channel is previously unassigned in an unknown optical link system to be commissioned. The modems are arranged within a group for communicating optical signals within the optical spectrum across the unknown optical link system to an unknown far-end network element. The method also includes provisioning the plurality of optical channels based on the measured optical performance parameters to enable data communication between the near-end network element and the far-end network element. Before commissioning, the unknown optical link system does not allow data communication between the near-end network element and the far-end network element.
