ADVANCED FIBER NODE

摘要

Circuitry of a hybrid fiber-coaxial network may comprise a first transceiver configured to connect the circuitry to an optical link, a second transceiver configured to connect the circuitry to an electrical link, a first processing path, a second processing path, and a switching circuit. In a first configuration, the switching circuit may couple the first transceiver to the second transceiver via the first processing path. In a second configuration, the switching circuit may couple the first transceiver to the second transceiver via the second processing path. The first transceiver may comprise a passive optical network (PON) transceiver and the second transceiver may comprise a data over coaxial service interface specification (DOCSIS) physical layer transceiver. The switching circuit may be configured based on the type of headend to which the circuitry is connected.
