Paper Abstract

The OPTONET system monitors up to 64 on/off fiber optic sensors. It is based on optical time domain reflectometry (OTDR). An optical pulse emitted by a pulsed laser diode is splitted between the sensors through an optical star network including delay lines to separate the pulses reflected back from the sensors. A dual wavelength emission board is implemented to guarantee line surveillance and optical path loss compensation, in order to minimize the error rate, and information discrepancy. These characteristics also combined with the well known advantages of fiber optic sensors make this system attractive in military or harsh environment. Various reflective sensors can be connected to the OPTONET system; we describe here sensors developed for a French Navy application.
