The Uni-T UT691-10 is a compact visual fault locator designed to detect issues in fiber optic installations, identify fibers, and perform routine maintenance tasks. The device uses visible red light with a wavelength of 650 ± 10 nm and offers two laser operating modes, allowing you to conveniently adapt its operation to the type of task at hand. The non-slip housing, IP54 protection rating, and compact design make this model well-suited for field work.
The UT691-10 model offers a laser output power of at least 10 mW and enables operation on fiber optic sections ranging from 8 to 10 km in length. This makes it better suited for more demanding applications where a greater fault location range is required. The universal 2.5 mm FC connector, along with continuous and pulse modes, enhance user comfort and simplify daily diagnostics.
The device is equipped with a 3.7 V 1050 mAh lithium-polymer battery, providing over 7 hours of operation. It features a battery level indicator, an LED flashlight, and an auto-off function after 15 minutes with manual adjustment. Weighing 62 g and measuring 130 × 38 × 27 mm, the model remains lightweight, comfortable, and ready for everyday use.
