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 design for a Tunable Cable Simulator with a minimum number of components and low insertion loss.

Electronic tunable cable simulator

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.
