Paper Abstract

We demonstrate a wide-area fiber sensor network composed of sensor nodes driven by the power of transmitted laser light. The sensor node produces optical signals by modulating a part of the laser light and sends it back to the monitor. The developed sensor node was driven with an input optical power of 1.7 mW. The number of the sensor nodes is also discussed theoretically. It is clarified that more than 1,000 sensor nodes can be placed along an optical fiber line by using a high-power laser diode of 1 W.
