Description: Differential group delay (DGD) is the time difference between the fractions of a pulse that are transmitted in the two principal states of polarization of an optical signal. For distances greater than several kilometres, and assuming random (strong) polarization mode coupling, DGD in a fibre can be statistically modelled as having a Maxwellian distribution.
What is jnxoptIfOChSrcSinkMaximumDifferentialGroupDelay?
The maximum differential group delay, in picoseconds, the link is specified to tolerate between the two polarization states of the optical signal; DGD grows with distance and polarization-mode coupling, so this is a key parameter for long, high-rate optical links.
