  • Publication number: 20240048875
    Abstract: Mapping of ports to other network components is generated by physically bending a fiber optic cable and then determining which optical network terminals experience a signal power loss (or receive attenuated signals) based on the bending. The physical bending can be done using a bending tool and the optical network terminals that experience the signal power loss can be identified using a back-end database operation. Generally, the correspondence between the physical bending and the power loss at the downstream components and or upstream components of the network is used to create the mapping of the ports at the splitter level.

  • Patent number: 10601465
    Abstract: Non-disruptive sweep measurements using low power coherent signals overcome the limitations of prior art frequency response systems for cable networks. Modulated or unmodulated, e.g. continuous wave (CW), test signals are transmitted into the network at a first or input point (input point is in the head end for forward sweep; input point is in the field for reverse sweep). The test signals are transmitted continuously at multiple frequencies, so as a composite they form a wideband, OFDM-like (orthogonal frequency-division multiplexing) waveform. A receiver at a second or output point generates power reading measurements, from which the frequency response of the network is produced.

    Abstract: First to third electrode layers (1) are laminated. A dielectric (22) disposed between the second and third electrode layers can be elastically deformed by pressing force from the first electrode layer-side to reduce distance between the second and third electrode layers. The first electrode layer is composed of first electrodes (Rxc) along a first direction (X). The second electrode layer is composed of second electrodes (Txcf) along a second direction (Y) intersecting the first direction. The third electrode layer is composed of third electrodes (Rxf) along a third direction (X) intersecting the second direction. During position-detection, the second electrodes (Txcf) function as transmission-side position-detection electrodes and the first electrodes function as reception-side position detection electrodes to constitute a mutual-capacitance touch panel unit (31).
