Richardson, Tex. - Valere Power's Line Power Solutions family extends battery backup from a centralized source to a remote location via unused telephone lines to support "triple-play" voice, video, and data service offerings and wireless access points.

"Triple-play services and IP-based television is one of the biggest changes in the telecom network in our generation, and these line-power products are a key enabler of this revolution change," said Greg Fasullo, Valere Power co-founder and vice president of sales and marketing. "The addition of the Line Power Solutions family means Valere now has a product offering for wireless and wire line networks that stretches from the central office (CO) to powered remote terminals and now to line-powered installations." Using a DC/DC converter at each end, the system sends power from the CO, where batteries or generators provide backup in the event of a power outage, across the telephone lines to a remote fiber-optic or wireless network cabinet. Thus the scheme reduces deployment costs significantly by removing the need to place AC utility service and batteries at each remote node.

The family includes the company's Head End and Far End DC/DC converters, which are designed to work with an AC/DC power system already in place. The converters are scalable from two to 40 inputs in a shelf to more than 400 inputs in a rack, and so are cost effective for systems ranging from small optical network unit (ONU) installations (50 watts) to dozens of large fiber-to-the-node (FTTN) cabinets (thousands of watts).

The Head End Converter (above) at the CO is a 2RU-high power shelf that can provide protected DC power for up to 40 remote nodes. Multiple shelves may be combined for larger installations. The Head End's power output can be configured for either -190, ±190, or ±130 VDC networks. It is rated for operation over -40 to +75°C. It comes with options for network monitoring via simple contact closures or full TCP/IP monitoring over SNMP. It can also be monitored via standard Valere controllers.

The Far End Converter is a modular 1RU system that is deployed in the remote cabinet. It is powered from the Head End product and provides -48 V power to the remote equipment. The Far End product accepts up to 10 converter modules per shelf, each with two 50-watt DC/DC converters.

The patented product technology offers greater than 90% power conversion efficiency. The converter modules are hot swappable. Both the Head End and Far End converters are now available in limited quantities. They will be available in production quantities later this quarter. Prices range from $200 for an entry-level Far End system to $1,000 for an entry-level Head End system.
