Survivable European optical transport network: capacity evaluation

The feasibility of a survivable all-optical transport network over standard single-mode fibre between eight major European cities is investigated. The chosen topology is intended to ensure survivability after a link or a node failure. The maximum transmission rate, limited by fibre dispersion, is estimated for three topologies and two modulation schemes: chirp-free intensity modulation and dispersion supported transmission. The network capacity is evaluated at 662 Mbit s-1 and 2.5 Gbit s-1.
