1.2 Gbit/s optical fibre transmission experiment over 113.7 km using a 1.528 μm distributed-feedback ridge-waveguide laser

Abstract

Optical fibre transmission experiments at 1.2 Gbit/s are reported over distances up to 113.7 km of conventional nondispersion-shifted fibre. The experimental system comprises a DFB laser, a PINFET and a parallel-processing regenerator. System penalties are observed which may be partly attributed to transient wavelength chirping and chromatic dispersion. Experiments using 83 km of dispersion shifted fibre show no penalties.
