Abstract: An ethernet-based communication system is provided. The communication system comprises: a first unit configured to generate a reference clock signal by using an input first ethernet signal, multiplex the first ethernet signal and a second ethernet signal in response to the reference clock signal, and output the multiplexed ethernet signals; a second unit configured to generate the reference clock signal by using the multiplexed ethernet signals, separate the second ethernet signal from the multiplexed ethernet signals in response to the reference clock signal, and output the first ethernet signal; and a transmission medium for connecting the first and second units and transmitting the multiplexed ethernet signals from the first unit to the second unit.

Abstract: Disclosed is an optical communication line monitoring apparatus comprising: an optical transceiver for transmitting management frames to remote devices connected to optical communication lines and receiving response frames transmitted from the remote devices; an optical time domain reflectometer (OTDR) for transmitting optical pulse signals to the optical communication lines and detecting reflection signals reflected from the optical communication lines, which have received the optical pulse signals; an optical switch for switching the optical transceiver and the OTDR at an input terminal thereof and switching each of multiple optical communication lines at an output terminal thereof; and a monitoring unit for determining whether or not a first optical communication line is abnormal based on a response frame transmitted from a first remote device, with the input terminal connected to the optical transceiver and the output terminal connected to the first optical communication line among the multiple optical communication lines.
