Product DescriptionKONGIA 20 mW VFL visual fault locator for identifying breaks and checking optical fiber continuity. Emits red light at 650 ± 10 nm, features a universal 2.5 mm connector for SC, FC and ST, and allows continuous or flashing light to be selected using a slide switch.
Product Description Read full descriptionHide description
KONGIA 20 mW VFL visual fault locator for identifying breaks and checking optical fiber continuity. Emits red light at 650 ± 10 nm, features a universal 2.5 mm connector for SC, FC and ST, and allows continuous or flashing light to be selected using a slide switch.
The stated range is up to 20 km as a reference and depends on fiber type, losses and test conditions. For 1.25 mm LC connectors, an FC-LC adapter purchased separately is required.
The textured aluminum alloy body provides a secure grip, and the flip cover protects the interface. Runs on two AA alkaline batteries. Do not look directly into the laser output or the end of an illuminated fiber.
Recommended Applications
Continuity and Identification
Visual tracing of compatible links and patch cords.
FTTH Installation and Maintenance
Visual checks during connection preparation and inspection.
Connection Inspection Near the Panel
Assist the visual search for leaks in accessible patch cords, bends and joints beside the ODF, with the link isolated and following the optical safety procedure.
