The present invention relates to a light beam and light hacking monitoring system of the optical cable using the loss and reflection amount monitor of the terminal to, while preventing the hacking of the optical fiber cable, particularly illegal detect only a portion of the optical signal transmitted in the optical fiber receives the data optical cable It relates to the security of the network to a new concept of a technology to keep thoroughly.
Near-ultraviolet include, without affecting the communication service it as operating the optical path applied to the monitoring system to the beam, bending the optical fiber is detected only a part of the optical signal by receiving the data being transferred 100%, and joined to hack wavelength to disturb the communication by being illegal hacking of the optical cable carried leak information to the analysis of the data carried on an optical signal, and results in a failure of the communication service, the problem of using the FTTH service as a negative is caused.
The invention as way hacked reflection filter connected to the optical adapter at illegal opening of the main facilities (TCU, artificial, and so on) are separated by a to solve the above problems, and monitor the loss change in the optical fiber according to the reflected wave byeonhwadoem, automatically notifies to the invention is characterized in that to prevent hacking of the optical line.
