
Basic Parameters
Up to 20 sensor optical fibers can be connected. Basic Parameters can be specified for
each of the fibers to be connected.
- Length
Specify the sensor optical fiber length of a fiber section as a value from 0.0 [m] to
50000.0 [m] in units of 0.1 [m].
- Group Index
Specify the group refractive index of a fiber section as a value from 1.3 to 1.79999
in units of 0.00001. Distance is calculated using the specified group refractive index.
- Loss
Specify the transmission loss of a fiber section as a value from -9.999 [dB/km] to
9.999 [dB/km] in units of 0.001 [dB/km].
Tip
- The Stokes and anti-Stokes signals of the Raman scatter suffer different fiber loss because of their
different wavelengths. Specify the differential loss for a fiber section to correct for this type of
temperature error.
