Feedback-Based Configuration Of A Hybrid Fiber-Coaxial Network

摘要

Circuitry of a fiber node which is configured to couple to an optical link and an electrical link may comprise an electrical-to-optical conversion circuit for transmitting on the optical link. The circuitry may be operable to receive signals via the optical link. The circuitry may select between or among different configurations of the electrical-to-optical conversion circuit based on the signals received via the optical link. The signals received via the optical link may be intended for one or more gateways served by the fiber node or may be dedicated signals intended for configuration of the circuitry. The circuitry may be operable to generate feedback and insert the feedback into a datastream received from one or more gateways via the electrical link prior to transmitting the datastream onto the optical link.
