u
When the distance range is “Auto”, the pulse width will be “Auto”, no need
the user to set. There will be different pulse width options accord to different
distance range.
9.7 Averaging Time Configuration
Test times affects the test trace SNR, the longer test time, the higher SNR and get a
bigger dynamic, so, when test long distance optical fiber and check far end event,
need to select longer test time.
Operation:
Click the time span number in time span zone.
u
Averaging time: Auto, Quick, 15s, 30s, 45s, 60s, 90s, 120s, 180s and etc.
u
The default value is 60s
9.8 Laser wavelength Configuration
Select certain single wavelength or multi select up to the entire wavelength.
Operation:
Click wavelength in wavelength parameter zone to realize test wavelength for single
selection or multi selection
purchased.
The effective wavelength will be different accord to modules
9.9 IOR setting
IOR is a key factor to affect the speed of laser transmission in optic fiber; and in this
case, IOR configuration has direct impact on the accuracy of measurement.
Generally speaking, the IOR parameter is provided by optic fiber manufacturer, and
it can be set to the accuracy of four digits after decimal point between 1.0000 and
1.9999.
9.10 Scatter Coefficient (Back scatter)
Scatter coefficient determines the value of backward scatter power. The
configuration affects the calculation of reflection value
Configuration zone is -10 to -70dB
