QS-Series Downstream Line Power

The QS-series line power solutions are designed to remotely and reliably power -48VDC network equipment using +/- 190VDC over existing copper lines deployed between central offices and remote outside plant (OSP) loads including, but not limited to, cabinets, broadband nodes, GPON (gigabit passive optical network) nodes, and small cell radios. New broadband and 5G services can be delivered over fiber optic lines, while the legacy copper lines are used to leverage central office battery backup and generator power sources in the event of an electrical utility grid outage.

The downstream converter solutions are available in 300W IP68 modules and shelf configurations of 650W and 1300W. The converters take +/- 190VDC input over twisted pair copper and convert it to -48VDC to power remote network equipment. This provides power distribution with battery backup maintained at a centralized location, helping to remove costs that would typically be associated with deploying and maintaining remote battery strings at load equipment.
