Method And System For An Optical Connection Service Interface

A system for communication, the system comprising:

• an optical data link comprising an optical fiber, coupling a first transceiver to a second transceiver, the optical data link being operable to:
• communicate an optical data signal at a first frequency utilizing the optical fiber;
• communicate a control signal for the transceivers at a second frequency, the second frequency being lower than the first frequency, utilizing the optical fiber;
• and
• communicate an Optical Connection Service interface (OCSi) signal at a third frequency that is between the first and second frequencies, utilizing the optical fiber.
