DC Line Power Over Copper Pairs
GE Critical Power - Line Power Solution
Line Power is rapidly emerging as a new alternative to using local power as means of powering Fiber to the Home, DAS and DSLAMs. By using centralized power and COE battery backup, Telcos distribute the power across normal copper pairs to power the ONT, antenna system or DSLAM, eliminating the need for AC power and batteries at the house or venue.
LINE POWER CO Converter Shelf
- The Line Power Systems is designed to remotely power -48Vdc network equipment reliably using +/- 190Vdc over existing copper lines deployed between central offices and remote outside plant (OSP) cabinets. New voice, video and data subscriber services can be delivered over fiber optic lines, while the legacy copper lines already deployed in the ground are used to leverage the central office battery backup and generator power sources in the event of an electrical utility grid outage. 16 Converter Shelf cards with 2 circuits each totaling 32 circuits.
- Upstream power converters take -48Vdc input and convert to +/- 190Vdc output power for distribution over twisted pair copper lines with appropriate input current limits and hold-over. Downstream converter shelves are available for 650 Watt and 1300 Watt applications. Downstream power converters take +/- 190Vdc input over twisted pair copper and convert to -48Vdc to power remote network equipment.
