Optical technology is now dominant in long haul communications networks and globally transports >50% of all traffic. The new optical devices and transmission systems now emerging offer revolutionary network options that could eclipse all previous operational gains. Specifically, coherent optics will allow very high traffic densities per fibre and optical amplifiers offer the possibility of full network transparency. Future long haul networks are thus likely to require far less hardware and control, but will offer a far greater utility and reliability than at present.
