VFL Pen-type Visual Fault Locator Fiber Optic Tester 5km/10km/20/km/30km high quality
Product description
The Pen Type VFL is the easiest way to identify fibers from end to end and locate polished connector end faces. Its red laser shines through most yellow-jacketed fibers to help you pinpoint breaks, bends, faulty connectors, splices and other causes of signal loss. It has a reach of up to 20 km*.
The convenient 3C-VFL-6S locates faults visually by creating a bright red glow at the exact location of the fault on single mode or multimode fibers.
Cost effective
The Pen type VFL's extremely high efficiency guarantees prolonged operation with two standard AAA alkaline batteries, typically providing 50 hours of uninterrupted operation. Priced to accommodate the tightest budgets, the 3C-VFL-6S Pocket Pal is a truly affordable way to locate faults in OTDR dead zones. Its effectiveness justifies purchasing one for just about every fiber technician.
We adopt the new technology for AL composite material make the PEN more light. And use import Mitsubishi LD Laser, make the lights signal more gathered and less attenuation.
Main features
Bright red laser at 635 nm
Pulsed and CW operation
50 hours of operation (typical)
Standard AAA alkaline batteries
Rugged and weatherproof
2.5 mm universal connector
Application
1.Insert the fiber into VFL through Fiber Connector. It can be used as reference of the multi- core cable
2.End to end fiber identification
3.Identify the breaks and micro-bend of the pigtail/fiber
4.OTDR dead zone fault locator: check the fiber fault point which OTDR can’t find (breakpoint, the beginning and the end of the fiber properties, and also the high loss section due to the microbending, for example: fiber optic patch cords, pigtails, the optical fiber core wire in junction box or bare fibe, etc
5.Identify the certain distance of fiber according to the power. Such as 10mw pen style VFL can
check the distance up to 20km
6.Operation

Replace the batteries
If the battery level is very low, please turn off the unit immediately and replace the batteries
1) Turn off the unit
2) Take out the cover of battery compartment and replace the old batteries with new ones.
Maintenance
1) Tlease handle it with care and keep the connector clean
2) Do not look into the VFL directly due to the laser is harmful to your eyes
3) Fix the batteries correctly
4) Take out the batteries if not in use for a period of time
