Abstract
将来の超高速光伝送システムの実現に向け、電界吸収型変調器を用いたOTDM(optical time division multiplexing)モジュールによる160Gbit/s(40Gbit/s×4)伝送技術の基礎検討を行った。160Gbit/s光信号は、新たに開発した80Gbit/s-OTDMモジュールにより得られた光信号を偏波直交多重することにより生成した。伝送実験では、通常分散ファイバ伝送路180km(光増幅器間隔60km×3スパン)に渡り、Q値で7(17dB)以上の値が得られた。また、さらなる長距離伝送の可龍性について送信光信号のOSNR(optical signal noise ratio)の観点より検討を行なった。
We investigated a feasibility of an ultra high-speed transmission using a 40Gbit/s-based optical time division multiplexing(OTDM) technique employing electro-absorption(EA) modulators. By use of a newly developed 80Gbit/s-OTDM module, 160Gbit/s polarization multiplexed transmission over 180km of standard fibers was demonstrated, and it was maintaining Q values of more than 7(17dB). In addition, an improvement of transmission distance was discussed from optical signal noise ratio(OSNR) at transmitters.
