Device and method for providing power to optical network utilities
Disclosed is a device ( 1000 ) for providing power to one or more Optical Network Utilities (NUs) ( 1100 ) in an optical network ( 1300 ) used to provide communication to a plurality of devices ( 1400 ) of subscribers. The device ( 1000 ) includes one or more Power over Ethernet (POE) adapters ( 1200 ) operatively coupled to the subscriber devices. The POE adapters are configured to derive AC power and data signals from the plurality of devices, and convert the derived AC power into DC signals. Further, the device includes a Power over Ethernet (POE) splitter ( 1500 ) operatively coupled to the POE adapters. The POE splitter is configured to split the DC signals from the data signals, and feed the DC signals to the one or more NUs for satisfying their power needs.
1. A device retro-fitted, for providing power to one or more Network Utilities (NUs) in an optical network, the device comprising:
one or more Power over Ethernet (POE) adapters coupled to a plurality of devices of subscribers, wherein the one or more POE adapters are configured to:
derive an AC power and data signals from the plurality of devices of the subscribers,
convert the derived AC power into 48V DC signals, and
output the 48V DC signals and the data signals to at least one POE splitter electrically coupled to the one or more POE adapters; and
the at least one POE splitter configured to:
receive the 48V DC signals and the data signals from the POE adapters,
split the 48V DC signals from the data signals,
down convert the 48V DC signals into 12V DC signals, and
provide the 12V DC signals and the data signals to the one or more NUs, wherein the 12V DC signals is equally distributed to each of the NUs.
2. The device of claim 1 , further comprising one or more cables for coupling the one or more POE adapters to the plurality of devices of the subscribers, and the one or more POE adapters to the at least one POE splitter.
3. The device of claim 2 , wherein the one or more cables comprise one or more CAT 5 cables.
4. The device of claim 1 , wherein the at least one POE splitter feeds the data signals to the one or more NUs.
5. The device of claim 1 , wherein the one or more POE adapters derives the AC power from an external power source.
6. The device of claim 1 , wherein the at least one POE splitter includes a down converter-to down convert the 48V DC signals into the 12V DC signals.
7. The device of claim 1 , wherein the one or more NUs comprise one or more Optical Network Units (ONUs).
8. The device of claim 1 , wherein the one or more NUs comprise one or more Optical Network Terminals (ONTs).
9. A method for providing power to one or more Network Utilities (NUs) in an optical network, the method comprising:
deriving, by one or more Power over Ethernet (POE) adapters, an AC power and data signals from a plurality of devices of subscribers;
converting, by the one or more POE adapters, the AC power into 48V DC signals;
outputting, by the one or more POE adapters, the 48V DC signals and the data signals to at least one POE splitter electrically coupled to the one or more POE adapters;
splitting, by the at least one POE splitter, the data signals from the 48V DC signals;
down converting, by the at least one POE splitter, the 48V DC signals into 12V DC signals; and
providing, by the at least one POE splitter, the 12V DC signals and the data signals to the one or more NUs, wherein the 12V DC signals is equally distributed to each of the NUs.
