Bien que le réseau optique passif à multiplexage par répartition en longueur d'onde (WDM-PON) soit connu comme un transfert à grande vitesse, il crée des coûts de canal élevés par abonné et une faible utilisation de la bande passante en raison du fait qu'une longueur d'onde est dédiée à chaque abonné. Il est donc impératif de réduire les coûts de canal par abonné et d'améliorer l'utilisation de la bande passante. Pour y parvenir, nous adoptons d'abord un WDM-PON existant, qui utilise la transmission bidirectionnelle avec une source unique pour un meilleur rapport coût-efficacité en utilisant un amplificateur optique à semi-conducteur réfléchissant (RSOA) à gain saturé. Deuxièmement, sur la base du WDM-PON existant, nous proposons un WDM/TDM-PON hybride amélioré, qui peut étendre le nombre d'abonnés pris en charge dans chaque longueur d'onde avec des séparateurs dans la couche physique et un format de trame duplex par répartition en temps partagé (TDD). dans la couche de contrôle d’accès aux médias (MAC). De plus, il peut contrôler la bande passante de manière adaptative grâce à un système d'allocation dynamique de bande passante (DBA) en fonction du volume du trafic. Comparé au WDM/TDM-PON hybride non basé sur TDD, il peut réduire les coûts de canal par abonné à partir du nombre étendu d'abonnés pris en charge dans chaque longueur d'onde. De plus, grâce au DBA, il peut améliorer le délai total de file d'attente et le débit, et ainsi augmenter l'utilisation de la bande passante.

Abstract: Although wavelength division multiplexing-passive optical network (WDM-PON) is known as a high-speed transfer, it creates high channel costs per subscriber and low bandwidth utilization due to the fact that a wavelength is dedicated to each subscriber. Thus, it is imperative to reduce channel costs per subscriber and improve the bandwidth utilization. To achieve these, we first adopt a existing WDM-PON, which uses the bidirectional transmission with a single source for cost-efficiency by employing a gain-saturated reflective semiconductor optical amplifier (RSOA). Secondly, based on the existing WDM-PON, we propose an enhanced hybrid WDM/TDM-PON, which can extend the number of subscribers supported in each wavelength with splitters in the physical layer and a shared-time division duplex (TDD) frame format in the media access control (MAC) layer. Moreover, it can adaptively control the bandwidth through a dynamic bandwidth allocation (DBA) scheme according to the volume of traffic. Compared to the non TDD-based hybrid WDM/TDM-PON, it can reduce channel costs per subscriber from the extended number of subscribers supported in each wavelength. Furthermore, due to the DBA, it can improve the total queueing delay and throughput, and thus increase the bandwidth utilization.
