FAR-REACHING DISTANCE:30mW visual fault locator can output very bright red light, up to 30 KM, and works great to check for old, misplaced cable or any damages inline of the cable.
CRASH-PROOF & DUST-PROOF DESIGN: The head of the VFL pen is made of reinforced stainless steel. The body is made of aluminum. Resistant to high impact and prevents ESD damage. The precision design is effectively dust-proof.
EASYandACCURATE IDENTIFICATION - It can easily and accurately detect and locate fiber breaks, poor connections, bending or cracking. The detector will emit a 650nm bright light for fiber tracing, breaks or faults in the fiber will refract the light.
WIDELY USED:2.5mm Universal Connector test for both single-mode and multi-mode ST/SC/FC Interface Fiber Optic cables,Red light output distance 20-30KM, Replaceable Ceramic core Design to prolong the lifetime.
PRACTICAL DESIGN AND EXCELLENT FUNCTION - Small size and lightweight, it is portable and easy for field test with multiple functions such as constant output power.
