There are several methods for testing and troubleshooting a Fiber-To-The-Home Passive Optical Network (FTTH-PON). The simplest and low cost method would be using a power meter which is able to detect the total loss on the network. However, to identify faulty sections of a network, segmentation need to be done together with the Optical Power Meter (OPM). Another testing and troubleshooting method would be using the Optical Time-Domain Reflectometer (OTDR). The OTDR within the network is able to detect the component that causes losses in the network. However, elements acting as a power splitter are not being able to be detected by the OTDR. Therefore, the Access Control System (ACS) is developed to bypass those elements and allows the use of OTDR entirely.
