The 650nm Visual Pen Fault Locator has been specially designed for field workers to provide you with an effective and essential tool. Cost-effective solution for fiber optic cable verification and optical network continuity check during and after installation. Find breakpoints, poor connections, nodes, or breaks in fiber optic cables. Operates in either CW or pulsed light. Output power: 30mW (30-32km). Connectors: 2.5mm general connection (SC/FC/ST interface available). Features: Continuous wave and pulse mode, constant output. Product Specifications Power: 30mW Wavelength: 650nm Applications: Fiber Single-mode / Multi-mode Fibers Connections: 1.25mm (or) 2.5mm FC universal connector (SC/FC/ST interface available). Housing Material: Aluminum. Dimensions: Length: 175mm, Diameter: 26mm. Note: 1.25 FC not included, adapter required. Power Supply: 2 AAA batteries (batteries not included). Simple and accurate recognition. Can easily and accurately detect and locate poor connections, deformations, or cracks. The detector emits strong 650nm light to inspect fibers and detect cracks or defects. This creates a glow around the damaged area. Test cables with optional 2.5mm fiberglass connectors. Practical design and high functionality, small and lightweight, easy on-site testing with many features such as constant power output, low battery warning, long battery life, and remote detection. Check optical faults with the portable and robust dust detector, robust design, to keep fiber optic cables in order. Package Contains 1 x Fiber Optic Cable Detector Pen 1 x Bag
