Optical fiber is considered an interesting transmission medium due to its capability to transport big volumes of data at high speed. Fiber optic networks have revolutionized communications, making engineers and scientists worldwide dedicate efforts researching and developing new methods and technologies to improve this type of networks. Computational models and dedicated network simulation software...
This paper presents two architectures for Radio-Over-Fibre (RoF) Access networks with Peer-to-Peer (P2P) capabilities. The architectures fully exploit the flexibility of a wavelength router based on the feedback configuration of an Arrayed Waveguide Grating (AWG) and an optical switch to enable P2P sessions and dynamic channel allocation of converged wired and wireless signals in an unified optical...
We present the architecture of a wavelength data rewriter that enables the centralization of optical sources in converged wired/wireless radio-over-fiber (RoF) access networks. In our proposal, wavelength reuse of downlink channels is enabled for uplink purposes. The system is based on a data extinction technique by gain saturation in a semiconductor optical amplifier (SOA). A Fabry-Pérot filter...
In this paper a promising optical packet switching node concept is presented for optical packet switched networks. We developed a new label processing approach for core nodes in a subcarrier multiplexed label swapping network with advantageous implemented functionalities. We present the experimental results of the implemented node.
