Kingfisher KI6354

The Kingfisher KI6354 is a Class 1 visual fault locator engineered to identify breaks, bends, and loss points across singlemode, multimode, and plastic optical fibers. Operating at 655 ± 5 nm, this compact instrument delivers visible red light to fault sites up to 5 km distant, enabling rapid continuity verification and precise cable route tracing in field installations. ## Technical Specifications • **Wavelength:** 655 ± 5 nm (650–660 nm range)
• **Output Power:** 350 µW (−4.6 dBm) for 9/125 µm fiber; 600 µW (−2.2 dBm) for 50 µm fiber; maximum <1 mW
• **Effective Range:** Up to approximately 5 km
• **Laser Class:** Class 1 per IEC 60825-2:2011
• **Power Supply:** 2 × 1.5 V AAA alkaline batteries
• **Battery Life:** Approximately 40 hours in blink mode
• **Dimensions:** 160 mm length × 18 mm diameter
• **Construction:** Metal and rubber body; drop-resistant ## Key Features • Single-button operation for power and mode selection
• Continuous light and flash (≈3 Hz) modes for enhanced visibility and range
• Universal 2.5 mm connector adapter; 1.25 mm adapter available
• Semi-translucent captive dust cap for laser status visibility
• Design prevents accidental activation and rolling
• Dust and water immersion resistant ## Typical Applications • Continuity checks on fiber optic cable links
• Physical fault location: breaks, sharp bends, high-loss points
