1650-km transmission of 50-Gb/s NRZ and RZ-DQPSK signals generated using an electroabsorption modulators-silica planar lightwave circuit hybrid integrated device

摘要

We demonstrate long-haul transmission of 50-Gb/s RZ and NRZ-DQPSK signals generated using an electroabsorption-based optical vector modulator. Transmission over 1650 km is achieved with less than 1.2 dB OSNR penalty relative to back-to-back performance.
