The FS-1.8G submarine system ist a large capacity, long repeater spacing transmission system. The transmission bit-rate is 1.87 Gb/s, four times as high as the earlier FS-400M, and also in accordance with the new sychronous digital hierarchy. A 100 km repeater spacing is achieved by combining 1.55 micron zero dispersion-shifted fibers with high-power DFB-lasers. This paper describes the system design, composition key-technique, and transmission test results for the commercial Fukuoka-Hamada route laid in June 1990.
