Abstract

To meet increasing demand of transmission capacity for Internet and Multimedia communication, ultra large capacity transoceanic undersea cable system with sub Tera bit/s per fiber pair will be realized with increasing the WDM channel count soon.[1,2] On the other hand, middle-haul system connecting the stations along the coast, the WDM festoon type undersea cable configuration using land repeaters and undersea cable is quite attractive to expand the aggregate cable capacity, since the umber of fibers in the submarine cable can be increased up to 100 fibers without optical repeater in the water and power feeding equipment. In such a system, the key issue is increasing the repeater span between land repeater.
