Line Power

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. Applications include triple-play infrastructure, wireless network distributed antenna systems, and FTTN/FTTH fiber infrastructure.

 

The Line Power Systems modular architecture provides both upstream and downstream converters. Upstream converter shelves are available for both central office applications and OSP cabinets. 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. This provides power distribution with battery back-up maintained at a central location to avoid costs of deploying and maintaining remote battery strings at OSP cabinet or customer premise locations.
