  • Patent number: 9537781
    Abstract: Aspects of a method and system for an extended range copper transceiver are provided. Reducing the communication rate provided by multi-rate physical (PHY) layer operations in an Ethernet transceiver may extend the range of the Ethernet transceiver over twisted-pair copper cabling from a standard connection length. The Ethernet transceiver may support up to 1 Gbps or up to 10 Gbps transmission rate over copper cabling. The multi-rate PHY layer architecture in the Ethernet transceiver may support signal-processing operations, such as echo cancellation and/or equalization, which may be applied to the reduced communication rate to enable range extension. The reduced communication rate may be achieved by reducing the symbol rate provided by the multi-rate PHY layer operations. Reducing the communication rate may also enable utilizing greater insertion loss cabling for a standard connection length.

  • Patent number: 8619604
    Abstract: A system and method for auto 10BASE-T/10BASE-Te selection based on cable characteristics. IEEE 802.3az defines a new 10BASE-Te PHY type for energy efficiency that runs on Category 5 or better cabling. Configuration of a PHY that supports both 10BASE-T and 10BASE-Te operating modes is based on measurements that provide an indication of channel characteristics.

  • Patent number: 8331430
    Abstract: A system includes at least one adaptive filter coupled to a first communication channel and at least one other communications channel. The at least one adaptive filter includes at least one set of adaptive filter coefficients. A memory stores at least one predetermined set of filter coefficient thresholds. The filter coefficient thresholds may be indicative of channel faults, channel to channel faults or a length of the channel. A controller is configured to compare the set of filter coefficients to the predetermined set of filter coefficient thresholds. The controller is configured to determine the information about the channels based on compare results.

  • Patent number: 8145922
    Abstract: A system and method for discovering a cable type and resistance for Power over Ethernet (PoE) applications. Cabling power loss in PoE applications is related to the resistance of the cable itself. A PHY can be designed to measure electrical characteristics (e.g., insertion loss, cross talk, length, etc.) of the Ethernet cable to enable determination of the cable resistance. The determined resistance can be used in powering decisions and in adjusting power budgets allocated to power source equipment ports.

  • Patent number: 8035399
    Abstract: A system and method for using a physical layer device to locate a thermal signature in a cable plant for diagnostic, enhanced, and higher power applications. Cable heating in specific sections of a network cable is detected through an automatic identification of a thermal signature in electrical measurements of a network cable. The correlation of the thermal signature to a specific section of the network cable enables network personnel to locate hot spots in the network cable with ease.

  • Patent number: 7948390
    Abstract: A system and method for continual cable thermal monitoring using cable characteristic considerations in Power over Ethernet (PoE) applications. Cable heating in PoE applications is detected through changes in electrical characteristics of the cable itself. By periodically monitoring the electrical characteristics such as insertion loss or cross talk of the cable, it can be determined whether the cable has exceeded certain thermal operating thresholds.
