  • Patent number: 8903250
    Abstract: Systems and methods are disclosed to provide an upstream rate between 1 Gbps and 10 Gbps in a cost effective manner in a 10 GEPON. In an embodiment, an optical network unit (ONU) transmitter includes a burst transceiver and a physical layer (PHY) including a high performance digital to analog converter (DAC), a pulse amplitude modulation (PAM) module configured to encode end user data using a modulation scheme having more than two levels, and a laser. The ONU transmitter transmits the encoded end user data to an optical line terminal (OLT) receiver, which demodulates the data using a PAM demodulator and sends it to a service provider.
    Type: Grant

  • Publication number: 20120030320
    Abstract: A system for managing energy efficiency and control mechanisms in a computer network having a plurality of network components is provided. The system includes a network power manager (NPM) coupled to at least one of the plurality of network components. The NPM is configured to receive and analyze power information from at least one of the plurality of the network components. The NPM is further configured to generate configuration instructions based on the analyzing of the power information and send the configuration instructions to at least one of the network components.
