Development Real Time Monitoring System of FTTH Using Fiber Bragg Grating Sensors

This paper deals with an optical fiber remote monitoring system by installing a reflecting filter in a Fiber to the Home Network. The existing FTTH technologies can't provide centralized real-time detection of optical cable failure and splitter degradation. To address this problem, this paper proposes a method for a real-time monitoring of Optical fiber Network and splitters using reflecting filters operating on the principle of fiber Bragg grating sensors. A reflecting filter enables remote monitoring of the optical cable bending status, connector status, and splitter degradation so that the telecommunication service provider's central office can identify faulty fiber and failure location.
