title: Chromatic dispersion compensation and fiber nonlinearity mitigation of OOK signals with diverse-VSB-filtering FFE and DFE.
abstract: We propose a diverse vestigial-sideband-filtering feed forward equalizer and decision feedback equalizer (DVSB-FFE-DFE), which is capable of compensating residual chromatic dispersion (CD) as well as mitigating fiber nonlinearity in on-off keying (OOK) systems. In DVSBFFE-DFE, the upper and the lower VSB filtered signals are jointly equalized with FFE followed by DFE. Simulation results show that in a 42.7 Gbit/s nonreturn-to-zero OOK system, DVSB-FFE-DFE can effectively mitigate the required optical signal-to-noise ratio penalty induced by residual CD and fiber nonlinearity.
