if i have two SMF (single mode fiber) and i want to make a relative propagation delay between them about 1 ps/km , how to set this parameter in optisystem optical fiber ?
You open the properties of the fiber optic block (which already comes as standard in SMF optisystem) will in Differential Group Delay and make the necessary modification
See this small file
but DGD differential group delay related to delay between two polarization modes not delay between propagation time between two different fibers !!!
Yes this related to polarization mode dispersion (PMD), thanks for the correction
You can do the following you can go into global variables create variable delay with the respective unit. The definition of the optical delay is the following “Generates optical signal delays. The delay is added by sending NULL signals to the output port. “With this you put between the amplifier output that accompanies the first fiber with the entry of the second most fiber amplifier
This block “optical fiber” by default the optisystem offers it with characteristics of SMF
And the dispersion compensated so reducing the length of second fiber in half, and fold the dispersion looks like this
(D1) * L1 + D2*L2 = 0
16.75 + 50 * (25) * (-33.5) = 0
I have helped
