 note = {P(論文), Ultra-high speed and ultra-long span optical transmission systems which are required for the future large capacity information transmission systems are surveyed. There are three optical transmission systems which are situated as next systems followed by the intensity modulation-direct detection systems. These three systems are, (1)optical fiber amplification transmission systems, (2)coherent optical transmission systems and (3)optical soliton transimission systems. Progress on erbium-doped fiber amplifiers (EDFA) and integrated planar lightwave circuits have enabled to develop these new optical transmission systems. These new age optical transmission systems successfully overcome the two main ploblems which limit transmission distance and information capacity.},
