Visual Fault Locator, Fiber Optic Cable Tester Pen, VFL Red Light Tool with FC to LC Adapter & 2.5mm Universal Connector (Black, 30 KM)

Professional Fiber Optic Visual Fault Locator – Pinpoint Faults with Precision Minimize network downtime and streamline your fiber optic maintenance with our Premium Visual Fault Locator (VFL). Whether you are routing cables in a data center, checking continuity in CATV networks, or preparing fibers for splicing, this high-efficiency red light pen accurately detects fractures, bends, and open connections in both single-mode and multi-mode fibers. Unmatched Penetration: Utilizing a highly stable 650nm optical light, it effortlessly travels through the fiber, creating a highly visible glow precisely at the fault location for quick identification. All-in-One Interface Solution: No need to carry multiple testers. The built-in 2.5mm universal connector handles SC/FC/ST cables, while the included FC to LC adapter expands your testing capabilities to high-density LC networks. Field-Tested Durability: Crafted with aerospace-grade aluminum alloy and matte paint, it is shockproof, dustproof, and features excellent heat dissipation to ensure a stable light source across operating temperatures. 【Specifications / Safety Compliance】 Wavelength: 650 nm Supported Fiber:Single-mode& Multi-mode Power Supply: 2 × AA Batteries Working Modes: Continuous Wave (CW) / Pulsed (Flashing) Safety Rating:Class IIIa（3R) Light Source (Power Output ≤ 5mW)

• POWERFUL FAULT DETECTION : Engineered for reliable long-distance fiber tracing. This robust visual fault locator features a high-efficiency 650nm red light source that easily travels through optical fibers up to 30km. It instantly illuminates breaks, bends, cracks, and poor connections with a bright red glow for rapid troubleshooting.
• UNIVERSAL 2.5MM COMPATIBILITY & LC ADAPTER: Designed to work seamlessly with your entire telecom toolkit. The standard 2.5mm universal connector flawlessly supports SC, FC, and ST interfaces. Additionally, the included premium FC Male to LC Female adapter ensures effortless compatibility with 1.25mm LC connectors, covering all single-mode and multi-mode fiber needs.
• DUAL WORKING MODES FOR EFFICIENCY: Adapt to any testing environment with the intuitive slide switch. Select 'Continuous Mode' for steady fault illumination, or switch to 'Pulsed (Flashing) Mode' to quickly trace and identify specific fibers in high-density server racks or bright outdoor environments.
• CRASH-PROOF & ESD-SAFE CONSTRUCTION: Built for the harshest field conditions. Featuring a heavy-duty aluminum alloy body and a stainless steel head, this VFL is highly resistant to impact, dust, and corrosion. The advanced anti-static (ESD protection) chassis grounding design safely protects your delicate optical components from electrical damage.
• PORTABLE DESIGN FOR PROFESSIONALS: Compact, lightweight (approx. 165g), and pocket-sized for ultimate convenience. Powered by 2 standard AA batteries, (Note: Batteries are NOT included due to shipping safety regulations)，it features a stable power circuit for extended battery life and a low battery warning. An essential, field-ready testing tool for CATV maintenance and data center wiring.
