Studies on Single Channel 80-Gbit/s Optical Signal Transmission Using SMF Lines Incorporated with Dispersion Compensation Fibers and Alternate Polarization Multiplexing. Ikuo Yamashita, Member, Hirihiko Shishida, Member, Shigeyuki Seikai, Member (Kansai Electric Power) Characteristics of single channel 80-Gbit/s optical signal transmissions using a standard single mode fiber (SMF) are discussed including the effect of alternate polarization multiplexing at the sending end. Allowable values of transmission line length, input optical powers to the SMF, and dispersion margin are evaluated based on bit error rate measurements for three line configurations, unrepeated lines, lines having a repeater with a 100-km spacing, and multiply repeated lines with a 60-km spacing. As for the transmission line length, error free transmissions are experimentally possible for the total lengths of 160km, 200km, and 300km for the individual cases. Unrepeated 160-km transmission experiments where an 80-Gbit/s optical signal with a single polarization is launched in the SMF are made for comparison. Superiority of the alternate polarization multiplexing is confirmed through the measurements of input optical power, optical pulse amplitude fluctuation, and optical spectrum broadening.
