Abstract
Polarization-mode-dispersion (PMD) tolerance of a duobinary modulation format is investigated. With the use of 2.5 Gb/s Mack Zehnder modulator for modulation and optical pulse shaping of a 64 channels (10.7 Gb/s) dense wavelength division multiplexing metro networks, the electrical filter needed in conventional duobinary is no longer needed. The proposed method cut down in the complexity and cost of the duobinary transceiver. This technique allows the use of 10 Gb/s MZ modulator for 40 Gb/s duobinary transmission. We also used electronic compensation to adaptively compensate for PMD/GVD.
