In today’s communication engineering, optical fibers have been increasingly popular for use as transmission lines, to connect different continents and regions altogether. The reason why optical fibers are so widely used for communications as compared to the use of conventional transmission line is because it boasts a greater bandwidth, attenuation and frequency independence, low cost, free of electromagnetic interferences and many more. With an increasing demand for fiber optics, there is also a need to detect breakage, faults etc in these fiber links and lines. Hence, this collaborated project development, Advanced GPON system with optical fault diagnostic functionality is to develop a system whereby detection of the fiber link and line faults can be done in more accurate and less time consuming manner. An overview of this development is to build a prototype with enough dynamic range and short dead zones to detect faults in a GPON link. The challenge is to use an entirely new algorithm, download it into a programmable chip and make sure that it works together with our designed Printed Circuit Board. The final product of the system is to ensure that it is able detect functionality faults in the links.
