VFL Visual Fault Locator Pen KI6358 | Kingfisher International
For use on single mode, multimode and plastic fibers, this is a low price 1mW fiber laser light tester that complies with the latest visible eye safety standards for fiber laser testers.
5– 30MW High-Precision Red Laser Pen Fiber Optic Visual Fault Locator
Using a 650nm red laser, it can identify fiber breaks, bends, and poor splices over distances ranging from 5km to 30km, making it ideal for telecom, data center, and FTTX applications.
Precision-Coupled Visual Fault Locator (PCVFL)
A high intensity visible red laser beam is precision-coupled into the optical fiber; breaks and micro-bends in the fiber deflect the red light into the fiber jacket, producing a red glow at the point of the fault.
