The formula varies, if you are using 1310 nm then it's 0.5 ps / the square root of km.
If you are using 1550 it is 0.2 ps/ the square root of km. Anything greater than these values adds to the PMD..distortions.
Andy, I think these are the right formulas. I can look it up if there not.....it's been a while
> Thank you, since PMD is measured in PS "Pico Second", do you know the limit of PMD in PS, before we see CSO "Composite Second Order" affecting the quality of RF signal.
