FTB-1v2 and FTB-1v2 Pro 147
6 Using the Optional Built-In
Power Meter and VFL
The FTB-1v2 and FTB-1v2 Pro can be equipped with an optical power
meter and a visual fault locator (VFL).
With the power meter, you can measure absolute power (dBm or W) or
insertion loss (dB). The power meter can detect modulated signals (1 kHz,
2 kHz, and 270 Hz). With the VFL, you can inspect or identify fibers. For
more information on how to use the power meter or the VFL, refer to the
power meter online help.
IMPORTANT
If you intend to take measurements with a very low power level,
make sure that your testing conditions are optimal to ensure the
best results (for example, do not use the VFL, make sure that the
other modules in your platform are not performing measurements
and that their internal parts are not moving, etc.).
