Abstract

Optical link fault detection and localization are significant in the Passive optical
network (PON) due to the passive nature of the network elements involved. A single
failure in the optical link can resort to a huge amount of data loss in the network.
However, deployment of fault detection and localization devices is extremely limited due
to the extra cost network operators need to pay and the reliability of the devices. PON
fault monitoring solutions have been investigated by the researchers over the decades; the
challenges for these monitoring techniques are the cost and complexity of their
deployment. Thus, this work proposes a technique for the detection and localization of
fault in the optical link of a PON Fiber-to-the-x (FTTx) network using optical reflectors.
The real-time back-reflected signal from the reflectors in the network will be utilized to
determine the optical link with fault. Experimental results obtained show that multiple
optical link impairments can be detected and localized in the PON FTTx based network
in-service, over a distance of 20 km, in a cost-effective manner. Measurements from a
standard Optical Time-Domain Reflectometer (OTDR) is used to prove the validity of our
technique
