Abstract: A high current RF choke network comprising a high current RF choke combined with an all-pass T-bridge filter. The high current RF choke may be connected to a grounded capacitor in the serial branch of the all-pass filter. In this case the parasitic capacitance of the RF choke practically becomes an integral part of the all-pass filter capacitor. The added capacitance in parallel to the parasitic capacitance of the high current RF choke practically neutralizes the resonances of the high current RF choke and thus extends significantly the operating frequency range of the network. The operating frequencies bandwidth range of the high current RF choke network is extended from the legacy range of 5 MHz to 1 GHz up to an extended range of at least 5 MHz to 3 GHz.

Abstract: A connector for connecting a coaxial cable to a components box is disclosed, the connector is adapted to receive a central conductor of the coaxial cable and to firmly connect it to a central pin in the connector using a seizing force of a springy element, without needing to use a fastening screw or the like and without needing to open the component box. The connector of the invention is further adapted to allow releasing the central conductor from the central pin without needing to unfasten a screw or opening the component box. The connector is further adapted to facilitate the connection of the coaxial cable to the connector in another orientation similarly, without needing to use a fastening screw or the like and without needing to open the component box.

The face plate comprising terminals, electronic circuitry, impedance matching units and a disturbances suppressor. The disturbances suppressor is designed to suppress the parasitic resonance of the transmission line that appears inside the extended operational frequency band of 1000 to 1800 MHz. The impedance matching units are adapted to match the impedance of the terminal with that of electronic circuitry.

Abstract: Embodiments of the invention provide a method, device and/or system for communicating over a wideband distribution network. The device may include, for example, a downstream conversion module for converting a legacy downstream electrical signal of a legacy downstream frequency band into an extended downstream optical signal of an extended downstream frequency band; and/or an upstream conversion module for converting an extended upstream optical signal of an extended upstream frequency band into a legacy upstream electrical signal of a legacy upstream frequency band. Other embodiments are described and claimed.

Abstract: A novel node device enables transmission of a wideband signal, in compliance with various acceptable transmission standards and protocols. The signal consists of the legacy spectrum of about 5-860 MHz as well as a new downstream spectrum of about 1000-2000 MHz and a new upstream spectrum of about 2000-3000 MHz or about 930-1100 MHz. The novel device enables transfer of additional data in the upstream direction employing multiple upstream bands without making substantial investment in upstream physical node splitting thus providing networking services to residential subscribers, as well as to small and medium-sized businesses (SMB), which may operate under existing DOCSIS protocols and controlled by standard DOCSIS routers (CMTSs).

Abstract: A system and method for spectral node splitting in cable TV network based on hybrid fiber-coax architecture is disclosed. Two-way optical signals carrying video and/or multimedia content are received at a signal distribution node. Portions of the received signals are processed according to the functionality the direction thereof. Certain frequency ranges are passed intact while specific different downstream and specific different upstream frequency bands are converted in a manner as to be allowed to be multiplexed into an extended broadband signal. The frequency bands within the extended broadband signal are distributed selectively among separate branches of the network. The frequency bands dedicated to the upstream traffic are received selectively from the separate network branches to be back converted and transmitted upstream to the network controller.

Abstract: A wideband high frequency signal splitter device utilized in a signal distribution network is disclosed. An input signal having a substantially extended frequency bandwidth is applied to an input port of the proposed signal splitter from the upstream portion of a signal distribution network. Within the signal splitter the signal is suitably divided into its constituent components. The constituent components include a low frequency component, a high frequency component and an AC current power component. The components are divided separately and re-routed to combiner units associated with suitable output ports. The separate components are combined and fed through the output ports to the downstream portion of the signal distribution network. The signal splitter device is also functional as a signal combiner device by combining separate signals received from the downstream portion of the network via the output ports and transmitting the combined signals to the upstream portion of the signal distribution network.
