生成用于超大容量相干探测传输系统的多级调制格式的新方案
摘要
We summarize several novel schemes to generate multi-level modulation formats for high capacity transmission system with high spectral efficiency. We show that multi-level 8QAM, 16QAM, 32QAM, and 64QAM (QAM: quatlrature amplitude modulation) optical signals can be generated by commercial optical and electrical devices. Employing these multilevel modulation formats, we have realized PDM-8QAM (PDM: polarization division multiplexing) 32 Tb/s and PDM-36QAM 64-Tb/s signals transmission over 580- and 320-km fibers, respectively.
