modeling optical fiber using matlab

(joined April 2015)
Participant

please i need to design WDM communication system by using PMMA polymer fiber with the following parameter attenuation 150 db/km , length 20 m,temperature 70 Celsius,core size 980 micro meter , cladding size 1mm.
as there isn’t PMMA polymer fiber component in optisystem so i need to model PMMA polymer fiber with the mentioned parameter using matlab component. if there is another way to use optical fiber component in optisystem please tell me it if not please tell me how i can model first glass optical fiber using matlab component to compare the results with the optical fiber component which already exist in optisystem software .
then i will model PMMA polymer fiber.
i need your help for my master degree study.
thanks.

      If you have more information about the fiber you can do it directly in OptiSystem, like core refractive index, cladding index etc.

      what about the other mentioned parameters?
      what about modeling optical fiber with matlab component?

      We are modeling fiber using split step Fourier method that solve Schrodinger equation.
      In case that your fiber is a special case of SMF or MMF, you can use Measured components of theses fibers with your parameters that Damian mentioned above to model your fiber.

      Abdallah Hi,
      Can you elaborate, how are you modelling and simulating fiber.
      thanks and regards,
      Sethi Rk

      Refractive index=1.4906
      Chromatic dispersion=dn/dλ = -0.043329 µm-1
      Group velocity dispersion
      GVD = 81.808 fs2/mm
      D = -446.31 ps/(nm km)
      Dispersion formula
      n2−1=0.99654λ2λ2−0.00787+0.18964λ2λ2−0.02191+0.00411λ2λ2−3.85727
