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.
