1. An optical Ethernet apparatus comprising:
- an optical receiver configured to perform photoelectric conversion on packet data received through an optical transmission medium;
an optical transmitter configured to perform electrophotic conversion for an output to an optical transmission medium;
a signal detector configured to detect whether the optical receiver receives an effective optical signal and output a resulting detection signal;
a system recovery controller configured to detect, as a system recovery command, an output from the signal detector that includes a predetermined pattern which is repeated a designated number of times for a designated period of time, and to output a system recovery control command; and
a system recovery processor configured to output a system reset signal or a system power ON/OFF control signal in response to the system recovery control command.

Abstract
An Ethernet-based optical transmission system, and particularly, an apparatus and method for controlling a remote optical Ethernet device. An optical Ethernet apparatus includes a system recovery processor configured to output a system reset signal or a system power ON/OFF control signal and a system recovery controller configured to detect a system recovery command that occurs when a predetermined signal pattern is repeated the designated number of times for a designated period of time, and to control the system recovery processor using the detected system recovery command.

17. An optical Ethernet apparatus comprising:
-
an optical receiver configured to perform photoelectric conversion on packet data received through an optical transmission medium; an optical transmitter configured to perform electrophotic conversion for an output to an optical transmission medium; a remote recovery command generator configured to output a remote system recovery command that occurs when a predetermined signal pattern is repeated a designated number of times for a designated period of time; and a remote recovery part configured to control ON/OFF of transmission power of the optical transmitter in response to the remote system recovery command output from the remote recovery command generator.

18. A recovery method for an optical Ethernet apparatus comprising:
-
detecting a predetermined signal pattern of a system recovery command; detecting a system recovery command that occurs when a predetermined signal pattern is repeated a designated number of times for a designated period of time, and, in turn, outputting a system recovery control command; and outputting a system reset signal or a system power ON/OFF control signal in response to the system recovery control command. - View Dependent Claims (19, 20)
