40 Gbit/s optical 3R regenerator using electroabsorption modulators for high-speed optical networks

摘要

To deploy 40 Gbit/s WDM based optical networks, 40 Gbit/s optical 3R regenerator was proposed and demonstrated using wavelength converters based on electroabsorption modulators. The optical 3R regeneration was evaluated at 40 Gbit/s by inserting the regenerator between two segments of transmission lines of 500 km length and Q factor improvement of about 1.5 dB was obtained after 1,000 km transmission, compared to without the regenerator.
