Terabit/s data communication in distributed computer cluster networks

High performance computer network architectures with interactive multi-task programs require concurrent and real-time program execution, which is achieved via inter-processor ultra-high data links requiring massive data transfers over long links that only fiber can support. We present a new method for inter-computer communication, which is characterized by elastic ultrahigh bandwidth, long fiber links, and low cost. We examine network topologies and we study a cost-effective point-to-point link capable to transport Terabits per second by utilizing wavelength division multiplexing (WDM) technology. We model and simulate exemplary cases at different fiber lengths and data rates. Simulation results suggest exceptional performance over 100 km links without amplification and with data transfers at Tbit/s.
