Abstract
A 160-Gb/s single-polarization differential phase-shift-keying transmission using time-domain optical Fourier transformation (OFT) was demonstrated over a 200-km installed fiber link with large polarization-mode dispersion (PMD). First, we suppressed differential group delay (DGD) by coupling to the principal state of polarization (PSP) launch, where the power penalty was 2.8 dB. Then, by further applying OFT, which enables us to reduce time-dependent DGD and second-order PMD that cannot be removed with the PSP launch alone, excellent error-free performance with a power penalty of 1.5 dB has been successfully achieved.
