BML-205-10 localizador visual de fallos 650nm 10mW comprobador de fibra óptica con alcance de 10km, conexión universal de 2,5mm, modo CW/pulsos, carcasa de aluminio

Field technicians troubleshooting fiber optic networks need a reliable way to pinpoint breaks, bends, and faulty connectors. The BML-205-10 Visual Fault Locator (VFL) from TriBrer delivers a powerful 650nm red laser with over 10mW output, making fiber faults visible up to 10 kilometers away. Simply connect the universal 2.5mm adapter to your FC, SC, or ST connector, select continuous or pulsed mode, and trace the glowing red light to locate the exact problem point—even through yellow-jacketed single-mode fibers and tight buffer tubes.

Key specifications

• Laser wavelength: 650 nm (visible red light)
• Output power: > 10 mW for bright, clear fault indication
• Detection range: up to 10 km on both single-mode and multi-mode fibers
• Connector interface: universal 2.5mm ferrule, compatible with FC, SC, and ST adapters
• Operating modes: continuous wave (CW) and pulsed (2 Hz modulation) for easy identification
• Laser type: Fabry-Perot laser diode (FP-LD) for stable output
• Power supply: 2 x AA batteries (not included), providing over 60 hours of continuous operation
• Durable aluminum alloy housing with pocket clip for easy carrying
• Laser safety class: 3R (avoid direct eye exposure)
• Operating temperature: -10°C to +50°C; storage temperature: -20°C to +70°C

Why choose it

This VFL combines high output power with a rugged, pocket-sized design, making it ideal for both field and lab use. The pulsed mode helps distinguish the test signal from ambient light, while the universal connector eliminates the need for multiple adapters. With over 60 hours of battery life, it keeps working through long shifts without interruption.

Ideal use cases

• Locating breaks and microbends in single-mode and multi-mode fiber links
• Verifying continuity and identifying fibers during installation or maintenance
• Testing patch cords and pigtails before deployment
• Fault isolation in FTTH, LAN, and data center environments

Good to know

The BML-205-10 is a Class 3R laser product; never look directly into the beam or view it with optical instruments. Always follow local safety regulations. Batteries are not included; use two standard AA cells.
