## Summary description

Visual Fault Locator electro base FLT-120 is a handheld fiber optic tester with 20 mW output designed for locating breaks, bends and faults in singlemode fiber links up to 20 km. It emits a visible laser to identify connection issues, check continuity and trace fibers during installation, maintenance and troubleshooting, improving fault isolation and repair speed.

## Long description

Visual Fault Locator electro base FLT-120 is a handheld fiber optic tester with a 20 mW visible laser output designed to locate breaks, bends and faults in singlemode fiber links up to 20 km. The device provides a clearly visible red light that helps identify connection issues, check continuity and trace fibres during installation, maintenance and troubleshooting. Its compact form factor and simple operation allow technicians to isolate faults quickly without complex calibration or additional equipment.
Advantages
The FLT-120 offers a high-intensity 20 mW visual output for enhanced visibility in singlemode networks, enabling detection of microbends, macrobends and end-face issues. Its handheld design combines portability with straightforward controls for single-button operation and rapid deployment on site. The tester supports long-range testing up to 20 km in singlemode fibre, reducing the need for repeated testing and minimizing downtime. Built to work with standard connectors, it streamlines integration into established workflows and reduces the time required for locating faults and verifying continuity.
Suitable for
Locating breaks and bends in singlemode fibre links
Tracing fibre runs during installation and cable management
Verifying continuity and connector integrity
Field maintenance and rapid troubleshooting of optical links
Pre-deployment checks and post-repair verification
Key specifications
Output wavelength: visible red laser
Output power: 20 mW
Maximum testing range in singlemode fibre: up to 20 km
Form factor: handheld, lightweight
Connector compatibility: standard fibre connectors (adapter-dependent)
Power source: internal batteries (user-replaceable)
How to use
Switch the FLT-120 on and select the appropriate output mode if multiple modes are available. Connect the correct adapter to match the fibre connector type, then attach the tester to the fibre under test or apply the visible laser to the end-face or jumper. Observe along the cable route and at connector points to identify bright spots that indicate breaks, bends or faulty terminations. For long runs, test from both ends where possible to narrow down the fault location. Turn the unit off and store it in a protective case when testing is complete.
Usage recommendations
Always follow safe laser handling procedures: avoid direct eye exposure to the visible laser beam and do not look into fibre ends connected to the tester. Use appropriate adapter fittings to prevent connector damage and verify battery status before field operations. For precise localisation on long or crowded cable ducts, combine visual detection with an optical power meter or OTDR measurements to confirm and quantify fibre loss.
