Live Fibre Identifier FI-20V | 10mW VFL up to 5km | 800 to 1700nm

The FI-20V is a handheld live fibre identifier that clamps onto a fibre or patch cord without cutting or disconnecting it, and shows whether light is present, which way the signal is travelling and the optical power reading from -40dBm to 10dBm across 800nm to 1700nm. It recognises 270Hz, 1kHz and 2kHz test tones with a buzzer, and has a built-in 10mW, 650nm visual fault locator (VFL) on a 2.5mm universal port for tracing breaks up to 5km. Features and Benefits - One clamp for 0.25, 0.9, 2.0 and 3.0mm fibre - bare fibre, buffered fibre and jumpers with no chuck changes. - Left and right signal LEDs - see the traffic direction before you touch a working circuit. - 270Hz, 1kHz and 2kHz tone recognition with buzzer - pick out the fibre carrying your test tone in a busy tray. - Built-in 10mW VFL - red light to find breaks and bad connectors up to 5km, through a 2.5mm ST, FC and SC universal port. - LED torch and backlit display - work in cabinets and manholes without extra lighting. - Trigger clamp - press the switch on the back to clamp the fibre and start the test automatically. - Two φ1mm InGaAs detectors - works on single-mode and multimode fibre. Applications - Finding the right live fibre before cutting or re-routing in FTTH and backbone work. - Checking signal direction at splice closures and ODFs. - Fault finding on patch leads and short runs with the VFL. - Telecoms maintenance in exchanges and data centres. Note: The VFL emits a visible red laser. Never look into the laser output or a live fibre end. The unit runs on 2 x AA dry batteries, which are not included.
