Transponder Extends the Reach at 10 Gbit/s

by Tami Freeman Fibers.org News, 9 May 2006 Dispersion tolerance is a critical factor for high-data-rate optical networks: the less dispersion a link can cope with, the more compensation it will need -- and this can be costly. With standard 10 Gbit/s transponders offering a reach of around 80 km, a typical metro link of 300-350 km will require several external dispersion-compensating modules -- commonly based on lengths of dispersion-compensating fibre -- to maintain signal integrity along its length.
