Optical access networks are evolving towards next generation solutions offering much higher bandwidth per end point. Moreover, the uninterrupted access to the network services is becoming crucial and therefore operators are now considering protecting their access networks. However, the cost factor is still very important due to the relatively low cost sharing in access segment. For this purpose, this...
Along with the competition on the telecom market and high reliability requirements of the emerging services operators and service providers are forced to increase connection availability of all users supported by their network. For economical reason most of the investment related to providing protection resources has been so far limited to the core and metro networks. On the other hand, increasing...
Optical access networks are being widely deployed due to their high capacity and scalability. The reliability of these networks is a key issue because of the impact of failures on both the number of interrupted services and significance of the service interruptions for the community. Consequently, the service interruption penalties that a network operator would need to pay are directly related to...
Passive optical networks (PONs) are considered as a promising solution for broadband access networks. Due to the growing demand for reliable service delivery, fault management in the network is becoming very significant. However, there is a trade off between the cost of protection and the level of service reliability. Since economical aspects are most critical in the access part of the networks, improving...
In this paper we take into account the business aspects of building wireless and optical access networks. A detailed view on broadband access network deployment costs, including both capital (CapEx) and operational expenditures (OpEx) is given. Main cost components of optical and wireless access networks have been identified, and the deployment costs of different architectures have also been presented.
