Repeaterless transmission of 80-channel AM-SCM signals over 100-km large-effective-area dispersion-shifted fiber

Abstract

We have investigated the SBS threshold and transport of AM-SCM signal over large-effective-area dispersion-shifted fiber (LEAF), truewave/reduced slope fiber, and standard single-mode tiber with external modulation. The transmission performance of CNR greater than or equal to 49.4 dB, CSO less than or equal to -60.5 dB, and CTB less than or equal to -60.3 dB has been achieved for externally modulated 80-channel AM-SCM signals over 100-km LEAF without in-line optical amplifiers.
