Remote Power Feeding

Upgrade your network while reducing your deployment and maintenance costs: power several remote sites from a central location by delivering power via twisted pair cables.

How it works?

In order to power remote sites, existing pair cables are used to link each site to a central installation.

Main DC power from a central installation is converted into 350Vdc, a voltage level ideal for long distances with very low losses. A second conversion takes place in the remote site where our down converters transform the 350Vdc into 48Vdc.

You can add splitters after up converters and before down converters to have an ADSL connection.

What’s in it for you?

Using centralized DC power equipment and batteries together with a network of copper lines to power the remote sites, bring you many advantages, such as:

  • Reduced space requirement: no need for AC power solutions and battery backup in the cabinet
  • Easy installation: no need for a local grid connection (no certification and validation) and no power systems with battery backup
  • Improved bandwidth: shorter distance between customer premises and active equipment
  • Safety: in case of failure, the power source is shut down rendering the installation harmless to the surrounding people
