100G and Beyond: Optical Transmission Activities in Brazil

摘要

Recent advances in high speed optical transmission from 100 Gb/s up to lTb/s per channel based on advanced modulation formats in progress in Brazil (CPqD) are exhibited. Optical transmission experimental results of 112G DP-QPSK WDM transmission, 224G DP.16QAM transmission with pre-filtering (achieving 8.96 b/s/Hz), and comb generation optimization for future Co-OFDM transmission are detailed. Digital signal processing set of algorithms built in-house for off-line processing are presented.
