  • Active network monitoring system and method thereof
    Patent number: 9209896
    Abstract: An active network monitoring system for detecting an abnormality at a position between a communication office and a client includes a first monitoring module disposed on the communication office, a second monitoring module disposed on the client and an optical splitter. The first monitoring module has a first processor and a first laser diode. The second monitoring module has a second processor and a second laser diode. The first processor sends a digital signal to the first laser diode. The first laser diode modulates the digital signal into an optical signal and sends the optical signal to the second monitoring module via the optical splitter. The second laser diode converts the optical signal back to the digital signal, and sends the digital signal to the second processor to generate an identification signal of the client. The identification signal is transmitted to the communication office via the second laser diode.
