VisiFault Visual Fault Locator

Product Information

The VisiFault Visual Fault Locator (VFL) is a visible light
source that helps you trace optical fibers, check fiber continuity,
and find faults such as breaks, bad splices, and tight bends in
fiber optic cable. It has a laser diode with a wavelength of 635 nm
(nominal) and is classified as Class 2. The VFL is compatible with
both multimode and singlemode fibers and has a universal adapter
for connectors with 2.5 mm ferrules. It can operate in continuous
or flashing mode with an output power of less than 1.3 mW.

Product Usage Instructions

  1. Remove the dust cap from the VFL’s output adapter and clean
    both the adapter and the connector on the fiber to be tested.

  2. Plug the fiber optic connector into the VFL’s output. The VFL’s
    universal fiber adapter accepts connectors with 2.5 mm ferrules
    (SC, ST, or FC). If you have connectors with 1.25 mm ferrules, use
    the optional 1.25 mm universal adapter.

  3. Press the power key to turn on the VFL.

  4. To toggle between continuous and flashing modes, press the
    FLASH key. The status LED indicates the VFL’s output status.

  5. Before disconnecting the VFL from the fiber, turn it off and
    replace the dust cap.

Tips: View the VFL’s light indirectly by holding a white card or
paper in front of the VFL output or the fiber connector emitting
the light. Please note that the VFL’s light may not be visible
through thick or dark-colored cable sheaths or connector dust
caps.

Maintenance

To clean the VFL, use a soft cloth dampened with water or water
and a mild soap. Do not use abrasives, solvents, or alcohol. If the
VFL’s light is dim or does not turn on, replace the batteries as
shown in the user manual.

The VisiFault Visual Fault Locator (VFL) is a visible light source that helps you trace optical fibers, check fiber continuity, and find faults such as breaks, bad splices, and tight bends in fiber optic cable.
Safety Information
W*Warning: Class 2 Laser
To avoid possible eye damage caused by hazardous radiation
· Never look directly into the VFL’s output (item A in
Figure 1). Momentary exposure to the VFL’s output will not damage your eyes; however, direct, long-term exposure is potentially hazardous. · Cover the VFL’s output with the dust cap when the VFL is not in use. · Do not open the case (except to open the battery cover to change the batteries); no user- serviceable parts are inside. · Do not modify the VFL. · Do not magnify or otherwise modify the laser output. Use only approved connectors and adapters. · Do not use controls, adjustments, or procedures not documented or approved by Fluke Networks.

Using the Visual Fault Locator
To use the VFL, refer to Figure 1 and do the following: 1 Remove the VFL’s dust cap; then clean the VFL’s output
adapter and the connector on the fiber to be tested.
2 Plug the fiber optic connector into the VFL’s output (A).
The VFL’s universal fiber adapter accepts connectors with 2.5 mm ferrules (SC, ST, or FC). For 1.25 mm ferrules, use the optional 1.25 mm universal adapter.
3 Press the key (B) to turn on the VFL.
4 To toggle between continuous and flashing modes, press
the FLASH key (C). The status LED (D) indicates the VFL’s
output status. 5 Turn off the VFL before disconnecting it from the fiber.
Replace the dust cap. Tips: View the VFL’s light indirectly by holding a white card or
paper in front of the VFL output or the fiber connector emitting the light. The VFL’s light may not be visible through thick or darkcolored cable sheaths or connector dust caps.
