摘要
由于传统的光纤故障定位方法不能有效解决空间分辨率和传输距离之间的矛盾,提出了一种改进的光频域反射(OFDR)技术,将原来技术中复杂的光相干处理简化为目前成熟的电相干和电处理,利用电域处理降低了对光源的要求,并通过仿真实验表明了该技术有效可行。
Conventional optical fiber faults positioning method can not solve the problem between spatial res- olution and transmission distance effectively, the paper proposes an improved optical frequency domain re- flectometer（OFDR） technology, the new technology simplified the optical coherence technology to electrical coherence technology, reduces the requirement of light source by processing data in electrical-domain, the pa- per proves the technology is effective and feasible through the simulation experiment.
