15mW Rechargeable Fiber Optic Visual

15mW Rechargeable Fiber Optic Visual Fault Locator – VFL Red Light Pen for FTTH Cable Testing

Quickly identify fiber optic cable breaks, bends, faults and continuity issues with this powerful 15mW Rechargeable Visual Fault Locator (VFL). Designed for professional fibre optic installation, testing and maintenance, this compact VFL uses a high-output 650nm red laser light source to help technicians locate faults and verify fibre continuity over long cable runs.

Featuring a durable metal pen-style body, rechargeable lithium battery, USB Type-C charging and continuous/pulsed light modes, this VFL is a convenient and reliable tool for field technicians, telecommunications installers, network engineers and FTTH contractors.

Key Features
Powerful 15mW Output: High-output red light source helps identify fibre breaks, bends, cracks and connection faults.
Easy Fault Detection: Clearly visible red light makes it easier to locate breaks and problem areas along fibre optic cables.
2.5mm Universal Interface: Compatible with common SC, FC and ST fibre optic connectors.
LC Compatibility: Can be used with LC connectors when paired with a suitable FC-male to LC-female conversion adapter.
Rechargeable Battery: Built-in 500mAh / 1.85Wh lithium battery eliminates the need for frequent battery replacement.
USB Type-C Charging: Convenient modern charging interface for easy field recharging.
Two Testing Modes: Choose between Continuous Wave (CW) and Pulse/Flicker (GLINT) modes.
Simple Slide-Switch Operation: Easy three-position control for quick operation.
Durable Metal Construction: Strong textured metal body designed for regular professional and field use.
Replaceable Ceramic Core: The 7mm internal ceramic core can be replaced if required.
Compact Pen Design: Lightweight and portable, making it easy to carry in a toolbox, technician bag or pocket.
