Test Procedure:
1. Select the VFL and then set its output mode to CW.
See “To use the Visual Fault Locator:” on page 3-7
for details.
2. Measure the center wavelength using optical
spectrum analyzer and the optical output power
level using optical power meter respectively. Check
that the output power level and wavelength of VFL
satisfy their respective specifications.
Note
The output power level and wavelength test is
performed with the Visual Fault Locator (VFL) set
to CW (continuous wave) mode. Do not perform
these tests with the VFL set to MOD (modulated
mode).
