Planeamento de uma rede de transporte de 80Gbps capacidade usando a tecnologia DWDM

Abstract

The new information age has brought about a remarkable growth in telecommunications services, where data services are dominantly in high demand. With this the increased demand for scalable equipment, transparency, terabit resource and flexible bandwidth allocation. In this also check the means communicated to transport data from one point to another or even from one point to multipoint according to the service, the SDH / SONET technologies will still continue to be used and informed if there is not all the conventional technologies are very strict, with specific bitrate and, therefore, unable to offer the flexibility, capacity and services required by operators today. As the demand for capacity in metropolitan and regional network areas soared, WDM (wavelenght multiplexing division) emerged, which is a technique for the simultaneous transmission of several wavelengths within a single optical fiber. Soon after came DWDM (dense wavelength division multiplexing), which is an evolution of WDM, definitively establishing itself as the most robust technology in the field of long distance transport. This work will be presented or exhibited from an 80Gbps capacity transport network through optical fiber in the Vodacom operator used or OSN1800V equipment.
