Abstract
A method and a device used for remote control by optical fiber signals and power over Ethernet includes a power sourcing equipment (PSE) outputting a direct current (DC) via at least one network cable to at least one powered device (PD). When the PSE receives a second restarting signal from a signal controller, the PSE stops supplying power to the at least one PD. An optoelectric signal converter converts an optical signal from an Ethernet Switch to a digital signal for the signal controller. When the optical signal is determined by the signal controller to be interrupted after a first time duration passes, the signal controller outputs the second restarting signal to the PSE for restarting. After restarting, the PSE re-powers the at least one PD. The at least one PD is restarted remotely without requiring working personnel at the location of the at least one PD, improving restarting efficiency.
