  • Client-side dynamic multi-routing power distribution system of FTTx optical terminal equipment
    Patent number: 9503190
    Abstract: A client-side dynamic multi-routing power distribution system of an optical terminal equipment integrates the Power over Ethernet, dynamic multi-routing power distribution and power management technologies to dispatch power to the optical terminal equipment from a home gateway to meet power demands of the off-premise optical terminal equipment and to greatly reduce the cost for laying power lines for the off-premise FTTx optical terminal equipment, thereby expanding the coverage of optical fiber broadband service. The client-side dynamic multi-routing power distribution system includes (1) a network signal processing and DC power supply module of the home gateway for dispatching power to the remote FTTx optical terminal equipment through a telecom line at a network interface; (2) a network signal processing and DC powered module of the FTTx optical terminal equipment for handling multi-routing power distribution and dynamic load balancing from a plurality of home gateways.
