Abstract :
A novel scheme of generating optical Manchester-duobinary signal format using a directly modulated chirp managed laser is proposed and experimentally demonstrated at 10 Gb/s. The generated optical Manchester-duobinary signal has narrow spectrum and has shown to achieve three times more chromatic dispersion tolerance in optical fiber transmission than that of the conventional Manchester signal. The impact of the optical spectrum reshaper on the dispersion tolerance of the directly modulated optical Manchester-duobinary transmitter is also experimentally characterized.
