dear damian,

i designed high negative dispersion fibre, when see the plot in particular point oly i got the slope value, so what does it mean,

and when we add that dcf with my single mode fibre , are we need to match the slope of single mode fiber with slope dcf

      The slope represents the third order dispersion and is in units ps/(nm^2*km). Depending on your pulse width and project you probably won’t need to compensate for third order dispersion.

      You designed a fiber in OptiFiber? Which plot were you investigating?

      Regards

      thank damain, and yes i designed quadruple triple cladd fibre for negative dispersion, that thing oly i am analyzing ,what thing i have to notice , because i got -886ps/nm-km as dispersion

        Hi Vignes,

        I’m afraid I am still not exactly sure what your question is. You designed a fiber with -886 ps/nm-km and you want to compensate for it with another fiber? You could use a fiber with 886 ps/nm-km with the same length to do that.

        Regards
