The OLP-88 TruePON tester is the first instrument on the market with functions for testing such as optical line terminal (OLT) and optical network unit (ONU) identification, verification of the optical network terminal (ONT) activation process, automatic certification of passive optical network (PON) power levels, in-service insertion loss testing, and detection of unknown/unauthorized ONUs. Together with accurate downstream and upstream power level measurements, the OLP-88 ensures greater reliability in PON network testing and faster network troubleshooting. Built-in G-PON network data analysis simplifies and speeds up installation workflows by automatically providing the service technician with all the information needed about the system.
