The Enhanced TDR feature is a software add‑on for the Passive Component Tester that builds on VIAVI’s long history in optical test solutions. It allows operators to immediately switch to ETDR mode after an IL or RL test failure to locate faults without moving equipment. This streamlines troubleshooting and improves accuracy. The feature also addresses challenges in measuring optical components shipped without connectors, where traditional IL/RL meters cannot detect individual fiber events. By combining loss and reflectance testing with time‑domain fault location, VIAVI delivers a more efficient and unified approach to optical connectivity verification.
