 Index of refractive (Ior): The refractive index of the fiber
affects the transmission speed of the laser in the optical fiber,
so whether its value is set accurately or not directly affects the
distance accuracy of the measurement. It is provided by
optical fiber manufacturers, which range from 1.0 to 2.0, and
the default value is 1.468.
Setting method: Under the parameter setting interface, press
[IOR], pop up the refractive index input interface, input the
refractive index of the measured optical fiber, press [OK] exit.
 Length of transmitting optical fiber: used to set the length
of OTDR starting end connecting to the guiding fiber, ranging
from 0 to 100. The unit is consistent according to the set unit,
which is usually 0 by default.
Setting method: press [transmitting fiber length] to pop up the
input interface, and then [confirm] to exit.
