30mW 30km Fiber Fault Locator, Red Light Pen Tester, LC/FC/SC Interface

[Accurate Identification] This visual fault locator can easily and accurately detect and locate fiber breaks, bad connections, bends, or cracks. It can operate in CW or pulsed mode. VFL emits a 650-nanometer red light for fiber tracing and positioning. Breaks or malfunctions will refract the light within the fiber. [Excellent Functionality] The fiber tester has several features, including constant output power, low battery warning, long battery life, and long-distance detection. Efficient fiber routing and continuity testing produce a bright light in the faulty area. [Wide Application] The universal 2.5mm connectors, designed for LC, ST, SC, and FC, can accommodate round and square fiber optic cables and test single-mode and multi-mode cables. Applicable to: Integrated cabling systems and fiber optic engineering; CATV engineering optical network maintenance; photoelectric communication; optical measurement reader engineering; optical equipment production and research. [Detection Distance] This visual fault locator has a strong 30mW light source output, constant output power, and a strong red light detection range of 20-30 kilometers within the fiber optic cable. A high-efficiency power supply circuit provides stable power in both wave and pulse modes. [Convenient Design] Battery included, no additional purchase required. Small and lightweight, pen-shaped design with a carrying case, easy to carry, easy to check for fiber optic faults, and visual fault location. The design uses a stainless steel head and aluminum body to prevent collisions and dust, and the casing design effectively prevents electrostatic discharge.
