Reverse Power Feed Series
To avoid the cost of running a powerline to individual units, the DPU can be powered through reverse powering from the customer premises using a Reverse Power G.hn CPE. Reverse powering the DPU does come with its own challenges.
First of all, the DPU needs to be powered even if only one end-user takes on the service. As there is no guarantee that everyone in the neighborhood or MDU will sign up for the higher speed services, the DPU needs to be functional, independent of the number of end-users connected.
Secondly there needs to be equal power sharing between subscribers. When multiple G.hn CPEs are connected to the DPU, each CPE needs to provide an equal amount of power to ensure one end-user doesn’t get loaded with the entire cost of powering the device.
It allows customer self-install which removes the need for a visit to the customer premises with its attendant cost, time, and logistical downsides. And last but not least, the DPU needs to work at all times, even during the edge cases.
This solution is utilizing the legacy coax for high-speed data and power – neither of which were envisaged when the cable was installed many years ago. In addition, being connected to the coax network means lightning effects need to be considered carefully in relation to device protection and continuity of reverse powering for all subscribers. Optimization is required to ensure an always-on network.
