Ultra low loss monomode fibre in the 1.3 µm to 1.6 µm wavelength range offers the
possibility of achieving very long repeater section lengths for high speed digital …

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 …

Long-wavelength single-mode optical fiber transmission technology has recently made
rapid progress and is now moving into the commercial operation stage. This paper …

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 …

By using an InGaAsP semiconductor laser emitting at 1.5? m, where silica fibre loss is at a
minimum, single-mode fibre transmission experiments were successfully carried out at 100 …

Optical fibre cables are currently available having transmission losses of 3 dB/km and
bandwidth x length products of 1 GHz km at an operating wavelength of 0.85 μm. At the …

Design considerations are made for the structural optimization of single-mode fibers used in
high-bit-rate and long-haul transmission systems in the long-wavelength region. As the …

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 …

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 …
