High-capacity lightwave transmission experiments

In recent years the demonstrated transmission capacity of single-mode fiber s has increased at over 4 dB per year. This progress has led to numerous sy stems experiments with capacities of 1 Tb/s and higher. Commerical systems have experienced similar capacity growth rates with Lucent's WaveStar(TM) 4 00G system providing up to 400-Gbls capacity per fiber pair. This paper des cribes the innovations that directly led to terabit/s systems experiments a nd is an extension of a recently published paper.
