The VFL is a pen-sized Fibre Optic Cable tester and visual fault locater, which sends a visible red laser down the fibre core.
The laser operates at 635nm and is suitable for the verification of Multimode and Singlemode fibre optic systems.
VFL can also be used to visually identify faulty splices; breaks in patch cords and breaks in cable within splice trays. Faults are clearly shown by a visible red light shining through the primary coating or sheath of the fibre under test.
Using a 635nm laser diode, this Class IIa visible safe laser injects almost twice the amount of optical power than traditional 670nm devices
This offers greater test distance and easier identification of cable impairments and the 2.5mm ferrule will accept any of todays standard ferrules.
