Mason, PL and Penty, RV and White, IH (1995) Extending the transmission distance of a directly modulated laser source using Bragg grating dispersion compensators. IEE Colloquium (Digest). 12/1-12/5. ISSN 0963-3308Full text not available from this repository.
Comprehensive computer modelling has been used to investigate the dependence of dispersion penalty on transmission length in an optical communications system employing a directly modulated 2.5Gbit/s DFB laser source and an optimised fibre grating dispersion compensator. Two grating apodization schemes, tanh and Gaussian, have been compared. The 2dB dispersion penalty transmission distance is shown to be approximately 520km along standard monomode fibre after compensation with a 5cm tanh grating. This represents a great improvement over the 150km range expected for a similar uncompensated system.
