Error-rate performances of a single-mode fibre transmission system are evaluated at wavelengths of 1.18 and 1.31 μm. It is proven that longitudinal single-mode oscillation of the laser is important in a high-bit-rate system at a finite dispersion wavelength. At a low dispersion wavelength of 1.31 μm, repeater spacing at 800 Mb/s was extended to 40 km, by developing a low-loss single-mode fibre cable, a stabilised optical transmitter and receiver and a single-mode optical connector.
