• and
• a node memory comprising a non-transitory processor-readable medium storing an orchestrator application, an optical topology and switching abstraction component, and storing processor-executable instructions that when executed by the node processor cause the node processor to:
• store, by the optical topology and switching abstraction component in the node memory, a first logical FRM model of the first flexible ROADM module, the first logical FRM model associating the first system port to a first logical system port, the second system port to a second logical system port, the first line port to a first logical line port, and a first logical connection between the first logical system port and the first logical line port;
• store, by the optical topology and switching abstraction component, a second logical FRM model of the second flexible ROADM module, the second logical FRM model associating the third system port to a third logical system port, the fourth system port to a fourth logical system port, the second line port to a second logical line port, and a second logical connection between the first logical system port and the first logical line port;
• transmit, by the orchestrator application, a first request to the first flexible ROADM module, the first request comprising one of an activation or a deactivation of a first group of passbands of the first optical signal based on a first particular logical system port;
• and
• transmit, by the orchestrator application, a second request to the second flexible ROADM module, the second request comprising one of an activation or a deactivation of a second group of passbands of the first optical signal based on a second particular logical system port;
• wherein the first processor-executable instructions, when executed by the first processor, cause the first processor to:
• receive, by a first control block, the first request from the orchestrator application;
• and
• responsive to the first request, activate or deactivate one or more of the first group of passbands based on the first particular logical system port of the first request, each first passband of the first group of passbands being associated with one of the first system port and second system port;
• and
• wherein the second processor-executable instructions, when executed by the second processor cause the second processor to:
• receive, by a second control block, the second request from the orchestrator application;
• and
• responsive to the second request, activate or deactivate one or more of the second group of passbands based on the second particular logical system port of the second request, each second passband being associated with one of the third system port and fourth system port.

An optical transport network, comprising:

• a first network element comprising a first processor, a first wavelength selective switch having a first line port and a first system port, and a first memory comprising a non-transitory processor-readable medium storing a first orchestrator application and processor-executable instructions that when executed by the first processor cause the first processor to:
• generate, by the first orchestrator application, a request to modify one or more aspect of an optical service;
• and
• transmit, by the first orchestrator application, the request via the first line port;
• a second network element comprising a second processor, a second wavelength selective switch having a second line port and a second system port and exposing a control block, and a second memory comprising a non-transitory processor-readable medium storing a second orchestrator application, an optical topology and switching abstraction component, a power control sequencer, and processor-executable instructions that when executed by the second processor cause the second processor to:
• store, by the optical topology and switching abstraction component, a logical ROADM model of the second network element, the logical ROADM model being a logical model one or more component of the second network element including the second wavelength selective switch;
• receive, by the second orchestrator application, the request to modify one or more aspect of the optical service;
• determine, by the second orchestrator application, one or more component of the second network element affected by the request and based on the logical ROADM model;
• determine, by the power control sequencer, one or more sequence of optical power control functions to be executed on the second wavelength selective switch, based on the request and the logical ROADM model of the optical topology and switching abstraction component;
• and
• transmit the one or more sequence to the control block of the second wavelength selective switch;
• and
• an optical fiber link optically coupled to the first line port and the second line port, the optical fiber link operable to carry an optical signal having the optical service in a plurality of passbands.
