  • Patent number: 10873522
    Abstract: An apparatus and method for testing an upstream path of a cable network are disclosed. The upstream path is tested by capturing and analyzing upstream data packets generated by a specific terminal device. A test instrument is connected at a node of the cable network. The test instrument establishes a communication session with the headend, informing the headend of an identifier of the device that will generate the test upstream data packet. The test upstream data packet is captured and analyzed at the headend, so that the results of the analysis can be communicated back to the test instrument. To speed up the packet capturing and filtering process, the upstream data packets can be pre-filtered based on packet duration and/or arrival time.

  • Patent number: 8963689
    Abstract: The present invention relates to the use of RFID technology to identify specific cables in a bundle, and in particular to a cable identification device in which RFID devices are connected to the far end of a plurality of cables and splitters, and an RF measurement device is used to identify each cable from the central location. The RF measurement device provides the AC RF electrical signal power required to pass through the at least one AC couple splitter to operate the plurality of RFID devices, and includes means to identify the unique identification numbers associated with the plurality of coaxial cables from the plurality of identification signals received simultaneously.

  • Patent number: 7949039
    Abstract: A home network testing device includes an input port with any one or more of a variety of different connectors for receiving different types of communication cables, e.g. coaxial cable, telephone cable, and electrical cable; and a testing apparatus section with a variety of different testing apparatuses for testing for the presence of different forms of home networks, e.g. MoCA, HomePlug, and HPNA. The present invention uses discrete components to analyze the physical layer in the time domain, looking for a specifically timed RF power pulse that is characteristic of and different in each of the network protocols.

  • Publication number: 20100087086
    Abstract: When connecting cable test equipment to standard F-connector style coax cables, a technician must use both hands to screw the cable under test into the test equipment or a test lead. In ideal conditions without gloves this is a rather simple task; however, a technician may have to repeat the procedure many times throughout a work day in extreme weather conditions, resulting in the technician having to repeatedly remove their gloves and expose their hands to the cold. A coaxial cable clip connector according to the present invention includes a smooth threadless connector, which fits into the cable under test, and an easily actuated clip, which fits over the coaxial cable connector housing to maintain a solid mechanical and electrical connection.
