Abstract :
Performance limits of 10Gbit/s transmission over standard single mode fibre (SMF) without the deployment of in-line erbium-doped fibre amplifiers (EDFA´s) are evaluated by means of numerical simulation. The fibre system was modelled using the standard split-step Fourier algorithm for the solution of nonlinear Schrodinger equation. The effect of group velocity dispersion (GVD) compensation scheme, degree of GVD compensation of the SMF, input optical powers to SMF and to the dispersion compensating fibre (DCF) has been investigated with the aim to maximize the distance between transmitter and receiver. We have found that post-compensation scheme performs better than the pre-compensation scheme and that, by careful selection of input powers and degree of GVD compensation, it should be possible to keep the bit-error-ratio (BER) bellow 10/sup -15/ for SMF length of 270 km.
