Product Overview

The VFL (Visual Fault Locator) is a professional handheld tool specially designed for fiber optic link fault diagnosis and location. It emits 650nm visible red laser, which can intuitively identify fiber breakpoints, micro-bends, cracks, connector contamination/misalignment and high-loss points at the fiber end face or connector, significantly improving fault diagnosis efficiency and construction accuracy. Adopting high-stability FP-LD laser light source, the red laser is bright and has strong penetration, compatible with both single-mode and multi-mode fibers. The pen-shaped body is sturdy and durable, with simple operation that requires no professional training. It is widely used in fiber optic wiring, acceptance, maintenance and emergency repair scenarios such as telecom, radio and television, data centers, park networks and FTTH/FTTx projects, and is an essential tool for fiber optic communication practitioners.

Detailed Technical Specifications

Key Features & Advantages

• High Precision Fault Location: High-brightness 650nm red laser, clearly identifies breakpoints, bends and connector defects, improving fault diagnosis efficiency by more than 3 times.

• Multi-Power Optional: 1/5/10/20/30/50mW multi-power options, covering 5-50km full scenarios, suitable for both short-distance home entry and long-distance trunk line maintenance.

• Dual Working Modes: Supports continuous (CW) and pulse modes, breakpoints are visible at long distances, avoiding strong light direct interference and ensuring more accurate positioning.

• Full Compatible Interface: 2.5mm universal interface, compatible with mainstream connectors such as FC/SC/ST/LC, no additional adapter is needed to adapt to most fiber optic projects.

• Portable and Durable: Pen-shaped lightweight design, one-hand grip; metal/engineering plastic body, anti-drop and dust-proof, adapting to complex working conditions such as outdoor and computer room.

• Long Battery Life & Low Power Consumption: AA battery power supply, low power consumption design, long continuous use time, reducing the frequency of on-site battery replacement and improving construction continuity.

Application Scenarios

The VFL is widely used in FTTH/FTTx home wiring and acceptance, quickly locating home fiber breakpoints and joint loss; fiber trunk and branch line construction and maintenance, troubleshooting long-distance link faults and bending points; CATV radio and television network maintenance, locating fiber link high loss and connector defects to ensure signal stability; data center and park network wiring and emergency repair, quickly locating fiber link problems in cabinets and buildings; fiber fusion and connector termination quality inspection, verifying termination consistency and reducing later maintenance costs. It is an essential tool for telecom operators, fiber optic installers and network maintenance teams.
