Des architectures de réseaux d'accès fibre telles que les réseaux optiques actifs (AON) et les réseaux optiques passifs (PON) ont été développées pour répondre à la demande croissante de bande passante. Alors que les opérateurs suédois préfèrent AON, ce n'est peut-être pas le cas des opérateurs d'autres pays. Le choix dépend d’une combinaison d’exigences techniques, de contraintes pratiques, de modèles économiques et de coûts. En raison de l'importance croissante d'un accès fiable aux services réseau, la disponibilité des connexions devient l'un des problèmes les plus cruciaux pour les réseaux d'accès, qui devrait être reflété dans la décision d'architecture du propriétaire du réseau. Dans de nombreux cas, la protection contre les pannes est réalisée en ajoutant des ressources de sauvegarde. Cependant, il existe un compromis entre le coût de la protection et le niveau de fiabilité du service, car l'amélioration des performances de fiabilité par la duplication des ressources du réseau (et des dépenses d'investissement) peut s'avérer trop coûteuse. Dans cet article, nous présentons l'évolution des réseaux d'accès fibre et comparons les performances de fiabilité par rapport aux coûts d'investissement et de gestion pour certains cas représentatifs. Nous envisageons des architectures à la fois standards et nouvelles pour un déploiement dans des zones peu peuplées et densément peuplées. Alors que certains travaux récents se sont concentrés sur les schémas de protection PON avec des CAPEX réduits, les efforts actuels et futurs devraient être axés sur la minimisation des dépenses opérationnelles (OPEX) pendant la durée de vie du réseau d'accès.

Abstract: Fiber access network architectures such as active optical networks (AONs) and passive optical networks (PONs) have been developed to support the growing bandwidth demand. Whereas particularly Swedish operators prefer AON, this may not be the case for operators in other countries. The choice depends on a combination of technical requirements, practical constraints, business models, and cost. Due to the increasing importance of reliable access to the network services, connection availability is becoming one of the most crucial issues for access networks, which should be reflected in the network owner's architecture decision. In many cases protection against failures is realized by adding backup resources. However, there is a trade off between the cost of protection and the level of service reliability since improving reliability performance by duplication of network resources (and capital expenditures CAPEX) may be too expensive. In this paper we present the evolution of fiber access networks and compare reliability performance in relation to investment and management cost for some representative cases. We consider both standard and novel architectures for deployment in both sparsely and densely populated areas. While some recent works focused on PON protection schemes with reduced CAPEX the current and future effort should be put on minimizing the operational expenditures (OPEX) during the access network lifetime.
