OLTs with meshed interconnection

A system supporting the daisy chaining of remote optical line terminals.

Daisy chaining of remote OLTs

A system for out of band control for legacy set top boxes in which an out-of-band (OOB) downstream signal containing control information for consumer premises equipment is transmitted to an end-of-line device, which converts it to an upstream OOB signal, then sends the upstream OOB signal in an upstream direction.

PON system optimized for internet of things

A system that includes a downstream device that receives an analog out-of-band signal received in a downstream frequency spectrum of the downstream device including control channel data for a consumer premise equipment. At the downstream device converting the analog out-of-band signal to a digital signal including the control channel data. At the downstream device converting the digital control channel data out-of-band signal to an analog signal including the control channel data at an out-of-band signal for the consumer premise equipment, where the converted analog out-of-band signal for the consumer premise equipment is at a frequency included in an upstream frequency spectrum of the downstream device.

Out of band frequency conversion using demodulation

In one embodiment, a switched amplifier is provided to amplify a data transmission. The switched amplifier may use a control signal that is received via a control signal channel in a transmission cable. Also, the switched amplifier may detect signal power to determine whether the data transmission is received at one of a first port and a second port. Data transmissions via the data transmission channel occur in a first direction and a second direction in a same frequency range in a time division multiplex (TDD) mode. Also, the control signal and data transmission are diverted from the transmission cable that transmits a type of signal different from the control signal and the data transmission. The switched amplifier is controlled based on the control signal or the signal power detected. The amplified signal is diverted in the first direction or the second direction via the data transmission channel back to the transmission cable.

Methods and systems capable of launching signal-carrying transverse electromagnetic waves onto a transmission line in the higher voltage region of the transmission distribution network. Such methods and systems may include a surface wave launcher located in the higher voltage region, a network unit located in a lower voltage region, and an arrester separating the surface wave launcher and the network unit, the arrester preventing voltage from arcing over from the higher voltage region to the lower voltage region where the arrester provides the signal to the surface wave launcher.

Disclosed is a device communicably coupled to a power transmission line and capable of launching transverse electromagnetic waves onto the transmission line. The waves propagate data received from a data source connected to the device through a center conductor surrounded by a shield conductor. The device may include a reflector and a coupler adjacent to each other, the reflector electrically connected to the shield conductor and the coupler electrically connected to the center conductor at an unshielded connection point, wherein time-varying E-fields between the reflector and coupler are caused by the data received from the data source, and induce a transverse magnetic wave that propagates longitudinally along the surface of the transmission line.

A data network for a multiple dwelling unit (MDU) enables efficient use of a MoCA (Multimedia over Coax Alliance) system. The data network includes a distribution point unit (DPU) connected to an access network, a plurality of modems in the MDU, a plurality of coaxial cables extending through the MDU between the DPU and the plurality of modems, and at least one network expander present between the DPU and a subset of the plurality of modems. The network expander can be a repeater that retransmits received signals, wherein the DPU, the plurality of modems, and the network expander exchange data via the plurality of coaxial cables using MoCA protocols.
