1.1.2 Test Parameters of OTDR
The test parameters of OTDR include: wavelength, range,
pulse width, attenuation, average times, index of refraction,
helix, etc.
l
WL: Used to set the test wavelength of OTDR.
²
The number of wavelengths available for OTDR is
determined by the module of the instrument, which is 4
for selection maximally.
²
In average, auto and dead zone test mode, it is
allowed to select more than one wavelength. In test, the
instrument will perform test in turn under each selected
wavelength until all the selected wavelengths are
tested before it stops. The instrument allows three
wavelengths
to
be
selected
for
test
maximally
simultaneity.
²
When the module of instrument has single mode
and multimode modules at the same time, please pay
attention to connecting the optical fiber under test into
corresponding test port to ensure correct trace.
