The built-in VFL of the OTDR module can shoot a red laser into the fiber under test. The red laser will be
visible at a marco bend, point of breakage and/or bare fiber end. The maximum detection range for the
PRO TP-P6 VFL is over 5Km, making it a very useful tool for fiber identification and detection, as well as
highlighting breaks, tight bends, splices and/or defective connectors in optical fiber spans.
Note:
The VFL is a perfect complementary tool to be used in conjunction with the OTDR, especially useful for
its ability to make visible the problems occurring in the area close to the OTDR, such as problems that
exist in the “Dead Zone.”
Note:
The VFL is only available with an OTDR module that has been ordered with the VFL option.
Fault locating with the VFL:
1. Clean the connector properly.
2. Connect the fiber to the VFL port.
3. Click the (Source)
icon in the OTDR main interface.
4. Check the “CW” (Constant Wave) option to emit a laser continuously, or check “Flash” to emit a
modulated laser at 1Hz.
5. Press the [VFL On] button to start the VFL. The
icon will then turn orange.
6. While the VFL is operational, press [VFL Off] to turn off the VFL. The
icon color will turn from
orange back to grey.
