分布式光纤传感技术与PON的融合

摘要

Theories,applications and key technologies of distributed optical fiber sensing system and PON are studied.The integration of distributed optical sensor network into PON is proposed,which is the future trend of optical fiber sensing and optical fiber communication.Aiming at the application of distributed optical sensor network in the security field,a fusion solution with EPON is put forward,integrating the OTDR technology into EPON for fiber optic fault detection and location.Experiments show that the approach is feasible.%研究了分布式光纤传感以及无源光网络的原理、应用及关键技术,提出了将无源光网络与分布式光纤传感网络融合的思想,既可以克服局域网与骨干网之间的速率瓶颈,又符合光纤传感与光纤通信融合传输的发展趋势。针对分布式光传感技术在安防领域的应用与EPON的融合提出了解决方案,即将OTDR技术融入EPON中进行光纤故障监测与定位,实验证明了该方案的可行性。
