Title :
Efficient planning of optical network upgrades
Abstract :
To summarise the introduction of 10 Gbit/s (TDM) or 4 X 2.5 Gbit/s (WDM) is well justified by the large reduction in cable-kilometers and equipment; a point-to-point 4 X 2.5 Gbit/s upgrade requires much less equipment (especially regenerators) than a 10 Gbit/s upgrade, unless low-dispersion fiber or dispersion compensation is applied. The introduction of wavelength routing is not justified considering the very moderate reduction in cable-kilometers or equipment compared to a 4 X 2.5 Gbit/s point-to-point link
