Systems and methods for optical data interconnection are described. One aspect includes a first signal converter that converts first high-speed HDMI electrical signals into high-speed HDMI optical signals, and transmits the optical signals over a first optical communication channel. A second signal converter encodes first low-speed HDMI electrical signals, converts these encoded signals into low-speed HDMI optical signals, and transmits these optical signals over a second optical communication channel. A third signal converter receives the high-speed HDMI optical signals, and converts these optical signals to second high-speed HDMI electrical signals. A fourth signal converter receives the low-speed HDMI optical signals, converts these optical signals to second low-speed HDMI electrical signals, and decodes the second low-speed HDMI electrical signals.

A framework for virtual network element of optical access networking has been designed to provide a cloud-residing core system (i.e., Mobile core controller or SDN controller) for running higher layers without requiring dedicated hardware at the edge of the network. In this framework, a service operator can create multiple optical access network connections for serving a single or multiple types of wired or wireless subscriber by programming (via software) optical ports of a Virtual Optical Edge Device to perform the desired MAC and/or PHY layer of a selected optical protocol. The Virtual Optical Edge Device in turn performs the desired PHY function or MAC and PHY function of selected protocol per each southbound port. The Virtual Optical Edge Device performs data abstraction function on all data associated with southbound ports and presents the core network a unified API via its northbound ports.

A communication device in a communication network includes at least one processor. The processor is configured to identify a first management information base (MIB) of a first occupied channel in the communication network, and a second MIB of a second occupied channel in the communication network adjacent the first occupied channel. The second occupied channel occupies a frequency band overlapping with an interfering signal band. The processor is further configured to calculate at least one proactive network maintenance (PNM) metric for each of the first and second MIB, and determine, from the calculated PNM metric, that an ingress of the interfering signal is detected on the second occupied channel.

A module for a hybrid fiber coax network includes a quad-output amplifier module that can include a port to couple to upstream devices, four ports to couple to downstream devices, and a configured port. The configured port can optionally couple to one of a radio frequency (RF) pre-amplifier or one or more optical transmitter modules or receiver modules. The module is initially provided in a default configuration as an optical node module. However, it can be pre-configured as a RF amplifier. When the configured port is coupled to the one or more optical transmitter modules or receiver modules in the default configuration, the module is operable as an optical node module. When the configured port is coupled to the RF pre-amplifier, the module is transformed to be operable as an RF amplifier.

Distributed and highly software reconfigurable CMTS (CMRTS) device, based on MAC and PHY units with FPGA and DSP components, for a HFC CATV network. The various CATV RF modulators, such as QAM modulators, may be divided between QAM modulators located at the cable plant, and remote QAM modulators ideally located at the fiber nodes. A basic set of CATV QAM data waveforms may optionally be transmitted to the nodes using a first fiber, and a second set of IP/on-demand data may be transmitted to the nodes using an alternate fiber or alternate fiber frequency, and optionally using other protocols such as Ethernet protocols. The nodes will extract the data specific to each neighborhood and inject this data into unused QAM channels, thus achieving improved data transmission rates through finer granularity. A computerized “virtual shelf” control system for managing and reconfiguring the FPGA and DSP based CMTRS units is also disclosed.

Premises apparatus and methods for providing aggregated high-bandwidth, low-latency, data service over a content delivery network including existing wireline infrastructure. In one embodiment, a network architecture having service delivery over at least portions of extant hybrid fiber coax (HFC) infrastructure is disclosed, which includes standards-compliant ultra-low latency and high data rate services (e.g., 3GPP and IEEE Std. 802.11 services) via a common service provider. In one variant, an expanded frequency band (e.g., 1.6 GHz in total bandwidth) is used over the coaxial portions of the HFC infrastructure, which is allocated to two or more sub-bands. Premises apparatus are used to support multi-service integration (e.g., aggregation of mobile wireless, premises, and other services), as well as incipient IoT applications and technologies.

A distributed CATV system capable of removing jitter of upstream IP packets from distribution nodes over a packet distribution network is described. The headend of the CATV system has a jitter buffer that temporarily stores each upstream packet until a scheduled time that is computed to equalize the delays among the different distribution nodes. Each packet is associated with a timestamp, and the scheduled time to remove the packet from the jitter buffer is computed based on the packet's timestamp and the equalized delay. The distribution node that sends the packet upstream to the headened also inserts the timestamp into the packet.

A communications system, a method for managing a communications system, and a controller, where the communications system includes a front-end device and a remote device, where the remote device includes at least one coaxial media converter (CMC), where each CMC includes a data over cable service interface specification (DOCSIS) processor supporting a broadband access service and an edge quadrature amplitude modulation (EQAM) processor supporting a video service, and the at least one CMC and the front-end device are connected using a digital fiber, and the front-end device includes a controller, where the controller is configured to manage the at least one CMC.
