5G wireless promises to transform yet again the way people live and work. Target specifications include per user peak data rates in the 1-50 Gb/s range and peak bandwidth densities of 10 Tb/s/km2. These tremendous speeds will come together with new capabilities, such as support for tactile applications, smart, high speed automotive systems, and disaster response features among others. Most base stations today already rely on a fiber connection for backhaul. With 5G networks, individual radio heads will use enough bandwidth to fill an optical channel or wavelength. Optical systems will become an essential part of the radio access network. In fact, the entire notion of a base station is breaking apart and instead cloud based baseband processing is emerging, which uses a “fronthaul” optical network between data centers and an ocean of radio heads. This transformation calls for a new type of optical system that is no longer ‘plumbing’, fixed in place and never touched. Instead optical systems need to be fully programmable to work smoothly with the rest of the software defined network (SDN) infrastructure and provide capacity when and where it is needed. This talk will examine this new frontier for optical systems and the associated transmission and control challenges. Recent results to understand and combat these challenges will be presented.
