| Abstract(in English) | A fault location technique for PONs is essential for improving the service reliability of optical fiber networks. OTDR is a technique that is widely used in conventional testing systems. However, it is unsuitable for PONs because it cannot distinguish Rayleigh back-scattered light from different tributaries we have proposed a PON fault location technique that uses Brillouin gain analysis, which can locate individual fault points in branched optical fibers without the need to add optical components to the PON system. In this paper, the proposed method is tested for 4-branched PON. The spatial resolution is improved up to 10m. |
