Abstract

Currently the world is experiencing a fast evolution of modern communication and information technologies due to infrastructure development. Consequently, there is a growing need to be able to quickly and resource-efficiently receive, transmit and process information, monitor different physical processes, environment. For this purpose, optical communication systems and optical fiber sensors are directly suitable. This paper focuses on a study of fiber Bragg grating (FBG) optical sensors, with particular emphasis on fiber optical temperature sensors. The experimental part is made of computer simulation by using RSoft OptSim software, during which the temperature effects on five FBG optical sensors central wavelengths are investigated. This developed optical sensors network is combined with an optical transmission system on one shared 20 km long optical fiber. Here the coexistence of multiple sensor network and 50 GHz spaced 4-channel non-return-to-zero (NRZ) intensity modulated wavelength division multiplexed (WDM) optical communication system with 10 Gbit/s downstream transmission is investigated and evaluated.

光纤光栅光学温度传感器网络的评价与研究

目前，由于基础设施的发展，世界正在经历现代通信和信息技术的快速发展。因此，越来越需要能够快速和资源高效地接收、传输和处理信息，监控不同的物理过程、环境。为此，光通信系统和光纤传感器直接适用。本文主要对光纤布拉格光栅(FBG)光传感器进行了研究，重点介绍了光纤温度传感器。实验部分采用RSoft OptSim软件进行计算机仿真，研究了温度对五种光纤光栅光传感器中心波长的影响。这种开发的光传感器网络与一根共享的20公里长的光纤上的光传输系统相结合。本文研究了多传感器网络与下行传输速率为10gbit /s的50 GHz间隔4通道非归零(NRZ)强度调制波分复用(WDM)光通信系统的共存。
