Optical links conform a large part of the current global communication network, and the trend is growing with the latest . deployments of Fiber-to-the-Home, (FTTH) networks and fiber backhauling of mobile and radio networks. With this background, the OQCG develops it's research in the following lines: Architectures in optical path switching networks, Architectures in optical packets switching networks, Photonic systems based on code division multiplexing for access networks and Reconfiguration in access and in-building networks, Optical processing of signals in Broadband Networks and Access Networks. Also, Advanced modulation formats, such as OFDM in optical networks, are being deeply theoretically and experimentally explored in different configurations in order to optimize the design paremeters to maximize the networks performance.
