160 Gbps S-band WDM transmission system over 1400 km using ITUT-652a and ITUT-655 fibers with low dispersion accumulation

摘要

Dispersion accumulation with the distance effects optical WDM system's performance severely. For every modulation format used there is a limit on maximum transmission distance due to dispersion accumulation. So dispersion compensation is required. But dispersion compensation can be avoided to a large extent by alternatively using different fiber standards. In this paper it has been proposed that the dispersion accumulation can be reduced to a large extent by alternatively transmitting in S-band and using fiber standards ITUT-652a and ITUT-655. To validate the claim, performance of a 16 channel 10 Gbps WDM system with the proposed method has been analyzed in terms of BER and Q-factor. And it has been observed that with the proposed scheme without any dispersion compensation the system performs well up to 1400 km.
