OmniOn Power Line Power

The Line Power system 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 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 650W and 1300W 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 backup maintained at a central location to avoid costs of deploying and maintaining remote battery strings at OSP cabinet or customer premise locations.

Shelf / Bay Options

Upstream shelves occupy two rack units (2RU) in a frame with a 23 inch wide shelf for 16 upstream converters, 19 inch wide shelf for 12 upstream converters, or a 6 inch shelf for 4 upstream converters. Downstream 1RU shelves are available in 10.75 inch width for 10 downstream converters or 6 inch width for 5 downstream converters. Fan tray options are available for each shelf configuration.

System Scale

The OmniOn upstream converter system can be deployed with two converter shelves and a redundant fan shelf for OSP cabinets. Three converter shelves and a redundant fan shelf can be deployed in central office applications.

Upstream and Downstream Converters

The QS982A upstream converter module delivers two circuits of +/- 190Vdc power. Each circuit is 100VA limited. The QS882A downstream converter module receives two circuits of +/-190Vdc power and delivers up to 65 Watts of -48Vdc power.
