    Abstract: Apparatus and methods for optimizing bandwidth utilization and services in a data network infrastructure. In one embodiment, the data network is a managed Hybrid Fiber Coaxial (HFC) cable network, and the network infrastructure is configured to enable dynamic allocate of frequency bands to individual consumer premises device (e.g., DOCSIS-compliant cable modems). In one variant, the improved network infrastructure enables creation of virtual Service Groups (vSGs), and allocation of individual ones of the CM to such vSGs, to some degree irrespective of topological or “hardwired” location within the network. The allocations can be dynamic, and based on factors such as load balancing, evacuation of portions of the physical network topology (such as to support infrastructure upgrades or replacement), or for yet other reasons such as relating to subscriber tier or service level agreement (SLA).

    Abstract: A customer premises device including an optical modem including at least one upstream laser is power controlled to provide one or more reduced power levels of service in response to a detected AC input power failure, and/or in response to control commands, e.g., from an optical line terminal (OLT). The commands control the customer premises device to switch to a reduced power consumption mode of operation. During the reduced power mode one or a few lasers are powered, e.g., on an intermittent but predictable basis. During normal operation mode each of the upstream lasers are powered. One or more receiver circuits are also powered off during reduced power mode operation in some embodiments. A schedule is used in some embodiments to control when one or more upstream lasers and/or receivers are powered. In some embodiments the schedule is determined based on information provided by the OLT.

    Abstract: An assembly includes a ring frame having first and second open sides and an electrical connector block; a mounting structure to which the ring frame is secured; a plurality of power and signal cable connection points defined on the ring frame; and a plurality of power and signal cables coupled to the power and signal cable connection points and the connector block. First and second covers are secured to the ring frame. Each of the first and second covers is open on one side facing the ring frame and defines a mounting cavity. A plurality of heat-dissipating electronic components are mechanically and thermally coupled to the first and second covers and located in the mounting cavities. The heat-dissipating electronic components are releasably electrically coupled to the electrical connector block.

    Abstract: A network includes a centralized power and signal distribution device deployed at a communication closet at a site. The centralized device includes a switch controller connected to a direct current power supply. The network includes at least one customer premises termination device connected to the switch controller, an access apparatus deployed at each of the multiple customer premises, and a power over cable system to carry power and signals. Each access apparatus connected to the at least one customer premises termination device and to provide access to user devices. The switch controller power cycles at least one of the switch controller, the at least one customer premises termination device, or applicable access apparatus in response to a power cycle command from a controller when at least one of the switch controller, the at least one customer premises termination device, or any access apparatus fail to transmit a status signal.
