✦ Synopsis

We report the demonstration of a successful duplex 20 Gb/s transmission system experiment over a single dispersion shifted fiber using two 4 = 2.5 Gb/s channels with a 1 nm spacing centered at the 1557 and 1538 nm wavelengths, respectively. For both upstream and downstream directions, we measured straight ( ) bit error rate BER performance with a 41 dB optical power budget at the BER of 10 y 9 . For a channel wavelength operating close to the zero dispersion wavelength, we derive an analytical expression for the signal-to-noise degradation due to fourwave-mixing products at a preamplifier receiver. Good agreement between experimental data and theoretical results is obtained.

We analyze the robustness of a novel type of transoceanic WDM soliton system based on synchronous regeneration. The effect of uncertainty of regenerator and filter passband position in a 4 = 20 Gbit / s WDM system is studied numerically. The results indicate that practical implementation of synchron
