The AFL FlexScan FS300-325 is a pocket-sized Quad OTDR combining multimode (850/1300 nm) and single-mode (1310/1550 nm) testing capability in a single compact handheld unit. Designed for both novice and expert technicians, it automates test setup, shortens test time, and simplifies results interpretation across a wide range of applications including data centres, FTTH PON deployments, and point-to-point networks. The FS300-325 supports SmartAuto, Expert, and Real-Time OTDR modes, and optionally FleXpress for fast point-to-point testing. An integrated optical power meter, light source, and visual fault locator (VFL) provide a comprehensive all-in-one field solution.
