Easy to use, fast, and lightweight VFL.

The Model F6230A Pen-style Visual Fault Locator is a commonly known as a VFL. The new product Model F6230A, is a pencil style VFL that features a universal connector accepting any optical connector style with a 2.5mm ferrule. It operates on a single 1.5V AA alkaline battery keeping the overall size to a minimum while providing long battery life. The VFL output is from a 650nm laser providing visibility to 8 km.

Unlike many VFLs today, the F6230A features a choice of continuous or modulated output and low battery indicator to alert the user when it is time to change batteries. The universal connector eliminates the inconvenience of having to use a patch cable for direct connection to fiber under test if connector styles are dissimilar.

This single basic tool is one that all installers, and maintenance personnel should have in their tool kit. It is the most economical test tool for quickly verifying continuity, checking the validity of patch cables before or after installation, test and find breaks in LANs, verifying short lengths of installed fiber, or looking for cracked fiber in splice cases, bad connectors, tight crimps in fiber cable, backbone breaks or anywhere light continuity needs checking.
