CPC H04J 14/0271 (2013.01) [H04J 14/0272 (2013.01); H04J 14/0283 (2013.01)] | 6 Claims |
1. An optical communication device of an optical ring network, the optical communication device comprising:
a first optical signal-processor configured to output a first optical signal having a first wavelength;
a first multiplexer/demultiplexer (MUX/DEMUX) configured to output the first optical signal in a first direction, and receiving and outputting a first reflected signal which is a reflected signal of the first optical signal;
a second optical signal-processor configured to output a second optical signal of a second wavelength;
a second MUX/DEMUX configured to output the second optical signal in a second direction opposite to the first direction, and receiving and outputting a second reflected signal which is a reflected signal of the second optical signal; and
a controller configured to analyze a connection state of a first remote optical communication device to which the first and second optical signals are allocated, based on the first and second reflected signals.
