Handheld, multi-function optical time-domain reflectometer commonly used for fiber optic cable testing—especially in FTTx, telecom, or field service environments.

Key features:

• Supports dual wavelengths (typically 1310 nm and 1550 nm) for testing both single-mode and multimode fibers

• Compact and portable, ideal for field use in installations and troubleshooting

• Measures dynamic range (e.g., 24–26 dB), offering insight into the maximum loss it can accurately assess over distance

• Provides metrics such as event dead zone, loss resolution, and distance accuracy for fault localization

• Often integrates additional tools like visual fault locator, optical power meter, and touchscreen interface
