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.

In one embodiment, a first group of splitters receives a group of signals from a group of transmitters. Each splitter in the first group of splitters splits a signal into a plurality of signals that are sent to a plurality of multiplexers. A multiplexer in the plurality of multiplexers receives one of the plurality of signals from each splitter in the group of splitters and multiplexes the received one of the plurality of signals into a multiplexed signal. The multiplexer sends the multiplexed signal through a single connection in which upstream signals are sent to a group of nodes and downstream signals are received from the group of nodes. A de-multiplexer de-multiplexes the multiplexed signal into the group of signals and sends the group of signals to the group of nodes via a second group of splitters that are connected to the group of nodes.

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.

An optical amplifier with network optimization techniques maximizes performance of a conventional optical amplifier with minimum user intervention. A circulator enables as much light as possible just below a stimulated Brillouin scattering threshold to be launched in to an optical fiber. An amount of reflected power directed by a circulator to a photo diode has a direct correlation to the quality of the received signal in a communications system.
