High Power 1mW 5KM Fiber Optic VFL Overview
The High Power 1mW 5KM Fiber Optic Red Light Pen VFL is a compact visual fault locator designed to quickly identify breaks, bends, poor splices, and connector faults in optical fiber links. It emits a visible red laser light that travels through the fiber, making faults easy to detect.
Ideal for FTTH, FTTx, and telecommunication networks, this handheld tool supports both single-mode and multi-mode fibers and provides an effective testing range up to 5 km for rapid troubleshooting and continuity checks.
Features
- High power 1mW red laser output.
- Visible wavelength around 650 nm.
- Testing range up to 5 km.
- Supports single-mode and multi-mode fibers.
- Universal 2.5mm interface for SC, FC, ST connectors.
- Continuous wave and flashing modes.
- Pen-style compact and lightweight design.
- Durable aluminum housing.
- Long battery life for field use.
Benefits
- Quickly locates fiber breaks and bends.
- Simplifies fiber continuity testing.
- Reduces troubleshooting and maintenance time.
- Portable design ideal for field technicians.
- Low-cost solution for first-level fiber diagnostics.
- Improves efficiency in FTTH and FTTx installations.
Applications
- FTTH and FTTx network installation and maintenance.
- Detection of fiber breaks, cracks, and sharp bends.
