Successful fiber management plays an increasingly important role in eliminating potential problem areas that can become both costly and time consuming over the life of the network. The fiber management experts at ADC have spent many years developing these techniques and providing solutions that match the ever-evolving fiber-to-the-premise FTTP network architectures. This paper will address the latest challenges facing service providers and present practical solutions for dealing with them - solutions that will save both time and operational expense over the long term. Passive optical network PON architectures are designed with no redundant paths therefore there is no network protection. Normally any maintenance requirement within the PON requires taking the network out of service until the problem is resolved. With that in mind providers need the fastest possible access to quickly isolate and repair problems while minimizing outages. Electronic gear at each end of the PON basically the optical line terminal OLT and the optical network terminals ONTs can communicate with each other. If the OLT loses contact with a single ONT it s logical to assume the problem is between the splitter output and that ONT. If the OLT loses contact with all the ONTs of one splitter the problem is between the central office CO and the splitter. However the electronics at the ends of the PON cannot identify the exact location of the problem. The only way to determine the exact location of the problem is to get onto the fiber itself and perform an optical time-domain reflectometer OTDR trace. The need for quick and easy access to .
