The handbook of optical communication networks

These factors are leading towards an integrated high-speed (and high-bandwidth) communication environment where all communication
needs will be supported by a single communication network. The latest trends indicate that bandwidth needs double every 100 days. The volume of data traffic has surpassed the volume of voice traffic. Such a monumental demand for bandwidth can only be met by using optical fiber as transmission media. Other bottlenecks such as bringing fiber to the desktop, or to the home, still exist. However, eventually these obstacles will be overcome. Emerging optical communication networks represent a step in that direction.
