The All-in-One Optical Fiber Cable Tester is a compact handheld diagnostic instrument combining a digital optical power meter (OPM) and a visual fault locator (VFL) into a single, portable tool. It is built to support quick fiber verification, continuity checks, and general fiber cabling diagnostics — ideal for field technicians, installers, and maintenance teams.
This unit typically includes measurement across multiple fiber wavelengths and a bright visible laser for easily locating breaks, bends, and connector issues. Its universal interface supports common connector types including SC, FC, and ST. The rugged, lightweight design ensures straightforward operation in datacenter, enterprise, and FTTH installations.

This tester is useful for everyday checks and quick field diagnostics, though it is not a standards-grade calibrated loss tester (e.g., it does not include a true multimode light source or insertion-loss testing capability). For full loss measurement, a calibrated light source or separate professional meter should be added.
