2. Set the wavelength span for your test. The default range is 1520 nm to

1580 nm. EXFO does not recommend changing this range unless you

want to perform a very specific test.

3. Set the distance range, in kilometers, from the list of available values,

or you can enter your own manually. Reducing the range to the part of

the link that you want to measure will increase measurement speed

and decrease the resulting file size. If you do not know the length of the

link, you can rely on the OTDR trace to estimate it.
