Abstract

An eight channel dispersion-managed soliton transmission is designed and evaluated. Each channel carries 80 Gbps pseudo-random bit signal. To reduce the crosstalk, polarization interleaved and a proposed modified polarization interleaved techniques are used. Key parameters, like; signal power, average dispersion and number of sections of dispersive fiber within one amplifier spacing are optimized. The performance of the system is monitored by Q-factor, OSNR, noise figure and optical eye-diagram. The proposed modified polarization interleaved system yields better results.
