Trileria VFL Fiber Optic HT-30, Visual Fault Locator Red Light Tester CATV — Open-Box, 21% Off

【Precise Fault Identification with Two Operation Modes】 This VFL (Visual Fault Locator) is a fiber optic tester that uses a bright <5mW red laser to pinpoint fiber breaks, sharp bends, damaged connectors, incorrect routing, and link continuity issues. Switch between continuous and flashing modes to distinguish signal from ambient light. For continuity, a red light at the far-end connector means the core is not broken. For long-distance faults, use an OTDR to find the approximate distance, then this fiber fault locator to pinpoint the exact spot. Note: Range depends on fiber condition—faults or high attenuation shorten visible distance. Waterproof/dark jackets may block red light.

【Universal Compatibility & Wide Applications】Includes 2.5mm universal adapter for SC/FC/ST and FC-to-LC adapter for LC fiber tester needs. Supports Single Mode (SMF) and Multimode (MMF). Works as a fiber optic tracer for enterprise, telecom, surveillance, campus, and data networks.

【Long Battery Life, Brightness Troubleshooting & Replaceable Ceramic Core】Uses 2 AA batteries (not included) for full-day field use. If this fiber light tester appears dim/weak: (1) replace batteries (most common cause); (2) check ceramic core for cracks; (3) clean connector with a cleaning pen. Install positive (+) toward laser head; reverse polarity prevents operation. Remove batteries for extended storage. Replaceable ceramic core extends product life and cuts maintenance costs.

【Compact, Portable & Built for Daily Field Use】Ultra-compact, lightweight metal housing. This fiber optic laser pen fits tool bags, maintenance kits, and field cases. Easy to operate with minimal setup—suitable for fiber techs, network engineers, IT admins, telecom maintenance, and security installers. Ready to use out of the box.

【Wide Applications & Complete Kit】This Trileria Visual Fault Locator is ideal for fiber installation, patch cord inspection, routing verification, connector checking, network troubleshooting, equipment room maintenance, surveillance deployment, enterprise cabling, and telecom infrastructure. Includes: 1× VFL, 1× FC-LC adapter, 2× lanyards, 1× manual, 1× carry bag, 1× box. Contact us with any questions—we're here to help.
