Handheld fiber tester for field technicians

This compact unit combines an optical power meter, a 10 km visual fault locator, an RJ45 cable sequence checker and an LED light. It measures ten standard wavelengths from 850 nm to 1650 nm across a -70 dBm to +10 dBm range, making it suitable for installing and troubleshooting single-mode and multimode links.

Pocket-sized housing with universal FC/SC/ST ports

The tester measures 11.3 cm × 6.3 cm × 2.6 cm and weighs little enough to carry in a pocket or backpack. Its rugged shell resists drops, while the built‑in FC, SC and ST interfaces accept common patch cords directly; a single FC‑to‑LC adapter is included for LC connections. Power comes from two AAA batteries (not supplied), and the backlit display can be toggled for indoor or outdoor viewing.

±0.2 dB accuracy with 500-record data logging

Measurement error stays within ±0.2 dB, and the meter shows both linear mW and logarithmic dBm values at 0.01 dBm resolution. Up to 500 test results can be stored and reviewed on the device, and a user calibration function lets technicians adjust the reference. The unit operates from -10 °C to +60 °C, so it cannot be used in environments colder than -10 °C or hotter than +60 °C.
