Dalga boyu bölmeli çoğullamalı pasif optik ağlarda (DBBÇ POA) yeniden modülasyon tekniğinin uygulanması geniş bant kapasitesi, hızlı veri iletimi yanında sunucu ve kullanıcılar için oldukça uygun maliyet sağlamaktadır. Bu çalışmada yansıtıcı yarı iletken optik yükselteçlerin DBBÇ POA’larda 5 Gb/s hızında veri silme analizi birçok parametre incelenerek yapılmıştır. Kurulan sistemin optimum çalışma aralığını belirleyebilmek için enjekte gücü -20 dBm -0 dBm arasında, ön gerilim akımı 20 mA-100 mA değerleri arasında incelenmiştir. Kalan sonlanma oranının 0,5 değeri ve altına düşmesini sağlayan sistem parametre değerleri belirlenerek renksiz kaynağın indirme yönünden kalan veriyi ne kadar silebildiği gösterilmiştir. Uygulanan renksiz kaynağın sistemi basitleştirerek birçok avantajı gösterilmiş ve daha önce uygulanmış olan Fabry Perot Laser Diyota alternatif olabileceği gösterilmiştir.

Data Deletion Analysis of Colorless Source in Passive Optical Network System

Öz

The application of the remodulation technique in wavelength division multiplexed passive optical networks (WDM PON) provides a very affordable cost for the server and users as well as broadband capacity and fast data transmission. In this study, data deletion analysis of reflective semiconductor optical amplifiers in WDM PON at a speed of 5 Gb/s is performed by examining many parameters. In order to determine the optimum operating range of the system, the injected power is applied between -20 dBm -0 dBm, and the bias current between 20 mA-100 mA. By determining the system parameter values that allow the remained extinction ratio under 0.5, it has been shown how much the colorless source can delete the remaining data at user end. It is demonstrated that how the applied colorless source simplifies the system and it can be an alternative to the previously applied Fabry Perot Laser Diode.
