Product Description










KFI-45 Optical Fiber Identifier with Built-in VFL for Live Fiber Detection
The KFI-45 Optical Fiber Identifier is a portable and non-intrusive testing device designed to identify live optical fibers without interrupting network traffic. It accurately detects signal presence, transmission direction, and modulation tones while protecting active fiber links. Featuring a built-in Visual Fault Locator (VFL), the KFI-45 also assists in locating fiber breaks and verifying fiber continuity. Compatible with 250μm, 900μm, 2mm, and 3mm optical fibers, this compact device is widely used in FTTH installation, telecom maintenance, data centers, CATV systems, and fiber optic network troubleshooting.
