Abstract
We compare PMD and CD tolerances of 10 Gb/s directly-modulated transmission formats, including directly-modulated RZ-DPSK, RZ-OOK and NRZ-OOK, using a 1.55 μm commercially-available DML. Along with an increased receiver sensitivity of 3 dB, we show experimentally that RZ DM-DPSK is more robust than directly-modulated RZ-OOK and NRZ-OOK to both PMD and CD.
