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 …

An attainable repeater spacing at 1.3 μm and 1.55 μm wavelengths using a step-index
monomode fibre cable is given, after detailed consideration of total loss as well as total …

Transmission characteristics for a 400 Mbit/s signal over a 104 km single-mode fibre are
reported. A DFB laser diode is restricted to a single longitudinal mode at 1.53? m. No …

An experiment has been performed over 102 km of low-loss monomode fibre at 140 Mbit/s
using an injection-locked source at 1.52? m. The experiment showed that long-haul …

It has been confirmed by a preliminary transmission experiment that a repeater spacing at
800 Mbits/s can be lengthened up to 7.3 km, by using a combination of a low-loss single …

Single-mode optical fiber transmission technology in the 1.0-1.8-μ m wavelength region is
reviewed. Owing to low fiber loss in the spectral region and to wide-band single-mode fiber …

Long-span single-mode fiber transmission experiments at 1.3 micron have been refined
toward higher digit rate and longer fiber span. Error-rate against receiving optical level …

We report a field demonstration of 20 Gb/s capacity transmission over a 360-km installed"
standard" fiber cable. The system consisted of two 10-Gb/s channels with wavelengths …

This paper describes an attainable repeater spacing for a high bit-rate single-mode fiber-
