Wilcom F6230A Visual Fault Locator

The Wilcom F6230A is a compact, handheld Visual Fault Locator—often called a VFL—that injects visible red light into fiber optic cables to pinpoint breaks, bends, or faulty connectors. The light leaks at fault points, making them visually identifiable.

Key Features & Specifications

• Design: Slim, pencil-like form factor, powered by a single AA battery for portability and long battery life.

• Laser: Emits red laser light at approximately 650 nm wavelength (some sources note 637 nm), delivering visibility up to 5 km—and in some specs, up to 8 km depending on conditions.

• Connector: Features a universal 2.5 mm ferrule connector, compatible with ST, SC, FC—and with an optional adapter, also LC and MU connectors.

• Modes: Offers both continuous (steady) and modulated (pulsing) output; the pulsed mode assists in distinguishing the active fiber among many.

• Indicators: Includes LED indicators to show when the laser is active and when battery is low

• Applications: Perfect for verifying continuity, testing patch cables before or after installation, spotting fiber breaks, identifying faulty splices, connectors, crimps, and tracing fibers within multi-fiber setups
