Devices, systems, and methods for determining adjustments used by an upstream transmitters to set the transmit power of at least one upstream OFDMA channel, where the adjustments are made using calibration values to determine constants in continuous expression of power as a function of frequency, and thereafter using the function to determine the adjustment.

Systems and methods for OFDMA power equalization

A passive optical network system having a node that is optically coupled to optical line terminals (OLTs), and that is optically coupled to optical network units (ONUs). The node includes at least one fiber link module (FLM), each FLM including an upstream multiplex conversion device (MCD), and a downstream MCD. The upstream MCD receives an upstream optical signal from the ONUs, converts the upstream optical signal to an upstream electrical signal, and transmits a regenerated upstream optical signal to the OLTs. The downstream MCD receives a downstream optical signal from the OLTs, converts the downstream optical signal to a downstream electrical signal, and transmits a regenerated downstream optical signal to the ONUs.

Multiplex conversion for a passive optical network

An optical network terminal receives optical digital data that includes chirp. The optical network terminal processes the signal representative of the optical digital data from the optical network terminal in a manner determines changes in logic levels based upon temporary wavelength changes of the signal.

Signal sensitivity for an optical line terminal

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 signal conductor formed as a metal oxide varistor (MOV), the MOV having a first MOV and a second MOV separated by an insulator. In some embodiments, the disclosed signal conductor may be used in a system communicably coupled to a power transmission distribution network, the system capable of launching transverse electromagnetic waves onto a transmission line, where the electromagnetic waves propagating a data signal conveyed to the system by the MOV.

Disclosed are one or more preferred geometric configurations for 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 and may include a reflector and a coupler adjacent to each other through a transverse magnetic wave that propagates longitudinally along the surface of the transmission line.

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.
