Transmission of 10Gb/s WDM signals over 4000 km of standard single-mode fiber with 106 km spans using all-Raman amplification and NRZ format

摘要

We demonstrate transmission of 36 x 10-Gbit/s WDM signals over 4134 km of standard single-mode fiber using all-Raman amplification and NRZ format. Wide-band fiber delay loop depolarizers are used in the Raman pump unit to reduce the depolarization dependent Raman gain.
