20090087181 | IN-WALL OPTICAL NETWORK UNIT - One embodiment provides an ONU that includes an optical interface coupled to an optical transceiver, which is configured to transmit optical signals to and receive optical signals from an OLT through the optical interface. The ONU also includes an ONU chip coupled to the optical transceiver and configured to communicate with the OLT through the optical transceiver. The ONU further includes an Ethernet interface coupled to the ONU chip and a power management module configured to provide power to the ONU chip and the optical transceiver using power delivered from a CPE through the Ethernet interface. In addition, the ONU includes a circuit board to which the optical transceiver, the ONU chip, and the power management module are attached, and a wall-mountable fixture, wherein the front side of the fixture includes an opening for the Ethernet interface, and wherein the back side of the fixture holds the circuit board. | 04-02-2009 |
20090047018 | METHOD AND APPARATUS FOR L3-AWARE SWITCHING IN AN ETHERNET PASSIVE OPTICAL NETWORK - One embodiment of the present invention provides a system that performs layer 3 (L3) aware switching in an Ethernet passive optical network (EPON) which includes a central node and at least one remote node. During operation, the system maintains a set of mapping information which indicates a correspondence relationship between a logical link identifier of a remote node, a medium access control (MAC) address for a subscriber coupled to the remote node, and an IP address for the subscriber. Upon receiving a packet which contains an IP address, the system selectively attaches a proper logical link identifier to the packet based on the mapping information and the IP address contained in the packet, thereby allowing only one proper remote node to receive the packet. | 02-19-2009 |
20080212965 | METHOD AND APPARATUS FOR DYNAMICALLY ALLOCATING UPSTREAM BANDWIDTH IN PASSIVE OPTICAL NETWORKS - One embodiment of the present invention provides a system that facilitates dynamic allocation of upstream bandwidth in a passive optical network which includes a central node and at least one remote node. Each remote node is coupled to at least one logical entity, which corresponds to a device or a user, that transmits upstream data to the central node and receives downstream data from the central node. The central node is coupled to an external network outside of the passive optical network through a shared out-going uplink. | 09-04-2008 |
