Soliton iletişim sistemlerinin optimizasyonu üzerine bir yaklaşım modeli

Uzun mesafe fiber optik iletim sistemlerinde, optik yükselteçlerin fiber zayıflamasını uygun şekilde giderdiği düşünüldüğünde, soliton haberleşme sisteminin toplam iletim mesafesi öncelikli olarak genlik ve frekans kayması ile belirlenir. Bu çalışmada, Gordon Haus Kayma etkisinin ve soliton soliton etkileşiminin neden olduğu genlik ve frekans kayması etkilerini birbirleri ile dengeleyerek veri iletim hızının ve tekrarlayıcı mesafesinin artırılması sağlanmıştır. Bu amaçla soliton haberleşme sistemi modellenerek önce sıfır faz farklı soliton darbeler için kayma hesapları yapılmış, sonra minimum kaymaya izin veren, optimum faz farkı hesaplanmıştır. Bu şartlar altında bulunan değerler için elde edilen optimum kayma değerleri simülasyon sonuçları ile de gösterilmiştir. Uygun faz farklı soliton dizilerinin kayma etkisini minimize ederek soliton haberleşme sistemlerinin performansım artıracağı sonucuna ulaşılmıştır.

An approach in optimization of soliton communication systems

In long distance fiber optic communication systems, when optical amplifiers are considered to remove fiber losses properly, total transmission length of soliton communication system is initially determined by amplitude and frequency shifting. In this study, the amplitude and frequency shifting effects caused by both Gordon-Haus Jitter and soliton-soliton interaction were compensated together. In this way, the increase of data transmission rate and repeater distance have been provided. To reach the purpose mentioned above by modeling soliton communication system maximum shifting has firstly been calculated for the zero phase difference between the soliton pulses. Then, the optimum phase difference which lets the minimum shifting has been calculated. For the optimum shifting values which are under the same circumstances have been simulated as well. As a result of minimizing the jitter effects of soliton trains with proper phase difference we have reached the result which verifies that it increases the performance of the soliton communication systems.
