The Anritsu MT9085B ACCESS Master is a handheld optical time domain reflectometer (OTDR) integrating testing, installation, certification, and troubleshooting functions for fiber optic networks. The unit combines OTDR, optical loss test set (OLTS), optical power meter, visual fault locator (VFL), and light source capabilities into a single instrument, eliminating the need for separate tools across FTTx, metro, core, mobile fronthaul/backhaul, and data center deployments.
