A coring tool for a coaxial cable has a tool holder and cutter bit mounted to the tool holder. The cutter bit is constructed from a conductive metal or alloy which is durable for rotatably drilling out and removing a dielectric core surrounding a central conductor of the coaxial cable, as the central conductor is preserved by passing into a central bore formed in the cutter bit. The cutter bit also includes a non-conductive sleeve or coating which prevents the cutter bit from electrically interconnecting, e.g., shorting, the central conductor to an outer conductor of the coaxial cable.

A half duplex amplifier for a cable network.

Half duplex amplifier

In one embodiment, an apparatus includes a bi-directional coupler for coupling an upstream signal and a downstream signal to a termination load. A test point detection mechanism is configured to detect when a test point device is inserted in a test point connector. The test point device is configured to perform a test of the upstream signal or the downstream signal. A switch is configured to switch from being coupled to the termination load to being coupled to the test point device when the test point device is detected as being inserted in the test point connector. The switch is configured to switch from being coupled to being coupled to the test point device to the termination load when the test point device is detected as being removed from being inserted in the test point connector.

A radio-frequency amplifier for a cable network includes a forward amplifier configured to amplify a high frequency range of signals that are provided downstream to a cable receiver of the cable network and a return amplifier configured to amplify a low frequency range of signals that are provided upstream to a head end of the cable network. An out-of-band forward amplifier configured to amplify a digitally protected video signal having a frequency in a range between 70 MHz and 130 MHz that are provided downstream to the cable receiver of the cable network and a notch filter configured to reject the amplified digitally protected video signal having the frequency in the range between 70 MHz and 130 MHz from being amplified by the return amplifier.

LC filtering with auto tuning

An amplification system for amplifying a service of a cable television network that includes a first amplifier receiving the service and providing a first output signal having a first frequency band with a first maximum downstream frequency to a first customer and a second amplifier. The amplification system includes the second amplifier receiving the first output signal and providing a second output signal having a second frequency band with a second maximum downstream frequency to a second customer, wherein the second maximum downstream frequency is less than the first maximum downstream frequency.

Methods and apparatuses are provided to modify existing overlay system architectures in a cost effective manner to meet the growing demand for narrowcast services and to position the existing overlay systems for additional future modifications. The implementations of the improved overlay system of this disclosure re-digitize narrowcast analog signals after they have been QAM modulated and upconverted to RF frequencies and replace the analog narrowcast transmitters with digital narrowcast transmitters. In the fiber nodes, the received narrowcast signals are converted back to analog signals and combined with analog broadcast signals for transmission to the service groups.

Digital optical transmitter for digitized narrowcast signals

Systems and methods for reducing the variation in the power of optical signals transmitted in an upstream direction, at the inputs of an active combiner in an RFoG CATV architecture preferably configured to reduce optical beat interference, so as to increase the dynamic range of a laser in the active combiner.

In some embodiments, a digital clock management system includes input signal conversion circuitry, logic circuitry and output signal conversion circuitry. The input signal conversion circuitry converts input signals to corresponding first digital data streams, each of which contains digital data synchronized to a first data clock. First digital logic circuitry converts the first digital data streams to second digital data streams, each of which contains digital data synchronized to the first data clock, and converts the second digital data streams to third digital data streams, each of which contains digital data synchronized to a common clock. Second digital logic circuitry converts the third digital data streams to a single digital data stream. The output signal conversion circuitry converts the single digital data stream to a modulated output signal.

Digital return receiver with digital data aggregation

A HFC network includes an optical node, a first fiber optic cable, and a second fiber optic cable. The first fiber optic cable has a first end that is connected to the optical node for delivering signals to the optical node. The second fiber optic cable has a first end that is positioned within the optical node. Optical fibers of the first optic cable are ribbonized and spliced to ribbonized optical fibers of the second fiber optic cable at a spliced connection such that signals can be transmitted between the fiber optic cables. An optical fiber of the first fiber optic cable is spliced to a connectorized fiber pigtail at a spliced connection, and the connectorized fiber pigtail is optically connected to a broadband optical transceiver in the optical node. The spliced connections are stored in a fiber splice tray within the optical node.

In one embodiment, a computing device detects a module that is inserted into a first slot. The computing device includes a first slot to operate with a first type of module and a second slot to operate with a second type of module. The first slot and the second slot include a same pin position for receiving a power supply pin from the first type of module and the second type of module. The module is communicated with to determine whether the module is the first type of module or the second type of module. The first type of module receives a first type of signal that is combined with a second type of signal from the second type of module. The computing device adjusts a power supply voltage to the power supply pin of the first slot from a first value to a second value when the first type of module is detected.
