01 Oct 2013TL;DR: Mixed integer programming models to facilitate upgrading the cellular backhaul using the free space optical (FSO) technology, a cost-effective and high-bandwidth solution are proposed.
Abstract: The increasing number of mobile devices and high-speed services accelerate the growth of traffic in cellular backhaul networks. The traditional technologies used in the backhaul, copper, radio links and optical fibers, either cannot offer high data-rate, or are expensive. In this paper, we propose mixed integer programming models to facilitate upgrading the cellular backhaul using the free space optical (FSO) technology, a cost-effective and high-bandwidth solution. Since the optical signal is transmitted along line-of-sight and FSO links are sensitive to weather conditions, we incorporate mirrors in the models to provide alternative paths for pairs of FSO nodes without line-of-sight, and increase the path diversity to enhance the resilience. Optical fibers existing in the backhaul are considered in the models and reused to decrease the upgrading cost and improve reliability. The presented models can deliver topologies for various requirements on cost and resilience. They can also be used to develop topology planning and optimization tools.

05 Nov 2007TL;DR: The potential use of radio over fiber techniques is analyzed and discussed in the context of recent large scale optical fiber deployments in Europe for broadband access but as well in thecontext of home or in-building networks to provide very high data rates to the end-users in harmony with expected evolution of broadband connections.
Abstract: The potential use of radio over fiber techniques (RoF) is analyzed and discussed in the context of recent large scale optical fiber deployments in Europe for broadband access but as well in the context of home or in-building networks to provide very high data rates to the end-users in harmony with expected evolution of broadband connections. Main challenges for RoF include the current evolution toward an all IP network, the rapidity with which networks evolve and the lack of standardization work.

TL;DR: In this article, a supervisory scheme is proposed to monitor the optical-path routing at the optical cross connects in all-optical transport networks, which can facilitate the network management in the optical layer.
Abstract: We propose and demonstrate a novel and effective supervisory scheme to monitor the optical-path routing at the optical cross connects in all-optical transport networks. Any error in optical-path routing due to failure in the cross connect can be detected without tapping off the power at the data wavelengths, and no dedicated monitoring light source is required. The scheme supports in-service surveillance. It can facilitate the network management in the optical layer of all-optical and reconfigurable transport networks.

TL;DR: The authors contend that optical system developments, which so far have followed a straightforward and logical path from direct link replacement to the proposed transwitching networks, will evolve towards passive (fiber-only) networks that could ultimately see the eradication of the central office.
Abstract: The authors contend that optical system developments, which so far have followed a straightforward and logical path from direct link replacement to the proposed transwitching networks, will evolve towards passive (fiber-only) networks that could ultimately see the eradication of the central office. To explain this view of the future, they briefly trace optical system developments to the present day before citing the technology developments that have led them to the conclusion. They discuss present network and technology trends, focusing on the reduction of the amount of electronic hardware, the disappearance of bandwidth efficiency as an important factor, and the state of the optical network today. They then turn to the future network and technology, showing how the central office can be dispensed with by operating the network on a radio mode, with each terminal assigned a specific frequency. >
