modeling optical fiber using matlab

[mohammed hosniParticipant]

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.

[mohammed hosniParticipant]

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

[Abdallah IsmailParticipant]

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,

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

[Abdallah IsmailParticipant]

Is this dispersion value is real?

[mohammed hosniParticipant]

yes

[mohammed hosniParticipant]

please find the attached files matlam m.file for modeling the attenuation and the dispersion of fibe that is just example but there is an error about the dispersion please help me to model the dispersion by matlab

[mohammed hosniParticipant]

that is optisystem file

[Abdallah IsmailParticipant]

I hope the attached files, helps you Mohamed.

[Abdallah IsmailParticipant]

There is a problem with the attachments

also this one

[Abdallah IsmailParticipant]

that is it

[Abdallah IsmailParticipant]

hope optiwave solve it
