The Fiberdyne Labs FD-VFL1A is a streamlined universal Visual Fault Locator (VFL).  The pencil style VFL features a universal adapter which accepts any optical connector style with a 2.5mm ferrule.  It operates on a single 1.5 Volt AA alkaline battery to keep the overall size to a minimum while providing long battery life.  Output is from a powerful 1mW laser at 650nm to provide visibility beyond 5 kilometers.

Unlike many other VFLs today, the FD-VFL1A features a choice of continuous or modulated output and a 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 the 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.

• Low Cost and Streamlined: The FD-VFL1A is a low cost, streamlined basic fiber test tool which is easy to handle and easy to store.
• LED Indicators: The FD-VFL1A provides LED indicators for active Laser mode (continuous or modulated), and Low Battery.
• Singlemode and Multimode Operation: Find breaks, bad splices, tight crimps, poor components, and bad connections.
• Single AA Battery: The FD-VFL1A uses one AA Alkaline battery for convenience.
• Optical Output Port: The FD-VFL1A features a universal adapter which can accept any 2.5mm ferrule such as ST, SC, FC and E2000 for examples.
• Pocket Clip: The FD-VFL1A comes with a handy pocket clip for easy storage.

Shown: HiLite

The HiLite and VFI 2 are compact but powerful visible red laser sources designed to troubleshoot faults on fiber optic cables. Light generated by these units will escape from sharp bends and breaks in jacketed or bare fibers, as well as poorly mated connectors. They can identify faults in fiber jumper cables, distribution frames, patch panels, and splice trays. The HiLite and VFI 2 are an excellent complement to an OTDR because they can locate faults inside the OTDR's dead zone. Other applications include end-to-end continuity checks, identifying connectors in patch panels and fibers during splicing operations. The universal connector interface provides fast operation with many connector styles without changing an adapter.

Features:

• 650 nm visible red laser source
• Compact size
• Universal connector interface for quick connection
• High power (1 mW)
