Abstract

Four-wave mixing (FWM) is an important nonlinear effect severely limiting the performance of optical fiber networks. In this paper, FWM impact on the uplink performance of dense wavelength division multiplexing gigabit passive optical networks (DWDM-GPONs) using standard single mode fibers (SSMFs) has been analyzed. Simulations have been carried out on the center uplink channels of 7-, 15-, 29- and 35-channel DWDM-GPON systems that have 12.5 GHz, 25 GHz, 50 GHz and 100 GHz channel spacing values. Signal-to-crosstalk ratio (SXR) variations occurring due to FWM impacts have been considered in evaluating the uplink performance. Simulation results exhibit worst-case values under FWM impacts and therefore are important in giving clues about choosing system parameters satisfying a minimum 23 dB SXR, which is an appropriate value for current GPON applications showing system reliability under FWM impacts.

Özet

Dört dalga karışımı (FWM) optik fiberli ağların performansını şiddetli biçimde sınırlayan önemli bir doğrusal olmayan etkidir. Bu makalede, standart tek-modlu fiberler (SSMFs) kullanan yoğun dalgaboyu bölmeli çoğullamalı gigabit pasif optik ağların (DWDM-GPONs) yukarı yönlü hat performansı üzerindeki FWM etkisi incelenmiştir. Kanallar arası boşluk değerleri 12.5 GHz, 25 GHz, 50 GHz ve 100 GHz olan 7-, 15-, 29- ve 35-kanallı DWDM-GPON sistemlerinin yukarı yönlü hat merkez kanalları için benzetimler yapılmıştır. Yukarı yönlü hat performansını değerlendirmede, FWM etkisi nedeniyle oluşan işaret çapraz karışım oranı (SXR) değişimleri dikkate alınmıştır. Benzetim sonuçları, FWM etkisi altındaki sistem performansının en kötü hal değerlerini sergilemekte ve bu nedenle, mevcut GPON uygulamalarında FWM etkisi altındaki sistem güvenilirliğini gösteren uygun bir değer olan minimum 23 dB SXR kriterini sağlayan sistem parametrelerinin seçimi için önemli ipuçları sergilemektedir.
