    摘要: A communication network includes first and second coaxial cables. The first cable transmits forward path, downstream signals to customer devices. The second cable receives reverse path, upstream signals from customer devices. In a preferred embodiment, the downstream bandwidth exceeds 500 MHz and the upstream bandwidth exceeds 500 MHz, such as frequencies of 5 to 550 MHz in both the downstream and upstream directions. A power inserter provides a ground to first and second shielding layers of the first and second cables, a first part of a differential power signal to a center conductor of the first cable and a second part of the differential power signal to a center conductor of the second cable. A tap is also provided for the dual coaxial system, so as to provide access to the signals and/or power of the first and second cables without terminating the first and second cables.

    摘要: A shielded cable assembly capable of transmitting signals at speeds of 3.5 Gigabits per second (Gb/s) or higher without modulation or encoding over a single pair of conductors. The cable has a characteristic impedance of 95 Ohms and can support transmission data according to either USB 3.0 or HDMI 1.4 performance specifications. The wire cable includes a pair of conductors, a shield surrounding the conductors, and a dielectric structure configured to maintain a first predetermined spacing between the conductors and a second predetermined spacing between said conductors and said shield. The shield includes an inner shield conductor enclosing the dielectric structure and an outer shield conductor enclosing the inner shield conductor.

    摘要: The present disclosure provides an electric cable, comprising two signal conductors, a resin insulating layer, an expanded polytetrafluoroethylene insulating film, an electromagnetic shielding film, two ground conductors, and a covering layer. The resin insulating layer covers the two signal conductors. The expanded polytetrafluoroethylene insulating film covers the resin insulating layer. The electromagnetic shielding film covers the expanded polytetrafluoroethylene insulating film. The two ground conductors are disposed at two sides of the electromagnetic shielding film. The cladding layer clads the electromagnetic shielding film and the two ground conductors. Through the expanded polytetrafluoroethylene insulating film, the electric cable can be applied to compact products, and the electric cable can be highly flexible such that the signal transmission performance would not be affected after being repeatedly bent.

    摘要: The disclosed embodiments provide a plurality of antennas that can be interconnected with each other and with a central receiver in a self-assembling manner, such that antennas can be added, removed, and replaced with minimal configuration. Each antenna comprises an antenna feed circuit, an input connector, and an output connector. Each of the antennas may be configured to assign a first set of signal channels at its output connector to a second set of signal channels at its input connector (or vice versa) according to a predetermined or dynamically determined mapping. Each antenna may be further configured to assign a signal channel at its input connector to the signal it receives at its antenna feed circuitry. By sharing the same configuration for mapping signal channels between the antennas' input and output connectors and feed circuitry, the antennas can be added or removed in a sequence of antennas using simple cable connections and without having to rewire the connections at the central receiver.

    摘要: A cable includes a jacket surrounding first and second insulated conductors and a first dielectric tape, wherein the first insulated conductor is twisted with the second insulated conductor with the first dielectric tape residing therebetween to form a first twisted pair. The cable's jacket may also surround additional twisted pairs, which are similarly formed. In alternative or supplemental embodiments of the invention, the first dielectric tape has a hollow core possessing a gas or material with a lower dielectric constant and/or at least a first side of said first dielectric tape facing to said first insulated conductor includes a plurality of ridges and valleys.
