30km Fibre Optic Cable Visual Fault Locator Tester Meter with 2.5mm Universal Connector for FC/SC/ST Connections – Red Light VFL Pen, Fiber Network Cable Adapter Test Kit, Light Source Tester

Precise Fault Detection – This visual fault locator accurately identifies and pinpoints fibre breaks, poor connections, bends, and cracks. It emits a bright 650nm red light for fibre tracing, with breaks or faults causing the light to refract. Advanced Features – Equipped with multiple functions, including constant output power, low battery warning, extended battery life, and long-distance detection. It efficiently verifies fibre routing and continuity, illuminating faulty areas clearly. Broad Compatibility – Designed with a universal 2.5mm connector, it is compatible with ST, SC, and FC interfaces for both single-mode and multi-mode cables. Ideal for integrated wiring systems, fiber optic engineering, CATV projects, optical network maintenance, telecommunications, optical measurements, and research applications. Extended Detection Range – This visual fault locator ensures stable output power, with a powerful red light capable of traveling 20-30 kilometres through fibre optic cables. Its high-efficiency power circuits provide reliable performance in both continuous and pulsed modes. Durable & Portable Design – Featuring a stainless steel head and an aluminium alloy body, this tool is resistant to impact and dust. The anti-slip knurled grip ensures secure handling, while its compact, pen-style design with a protective pouch makes it highly portable and convenient for fibre fault inspection.
