摘要
提出了一种采用单个光调制器产生频率稳定、偏振复用的矢量毫米波信号新方案。通过将双极化马赫-曾德尔调制(DP-MZM)和偏振复用16阶正交幅度调制(PDM-16QAM)相结合,实现了PDM-16QAM信号在系统链路中的有效传输,传输速率为64 Gbit/s@28 GHz,误码率被控制在4.2×10 -2以内。系统结构简单,频谱效率高,传输速率大幅提升,在未来光载无线通信网络中具有巨大的应用价值。
Abstract
In this paper, we proposed a new scheme of generating vector millimeter-wave signals with stable frequency and polarization multiplexing by a single optical modulator. We have experimentally demonstrated the delivery of 64 Gbit/s@28 GHz PDM-16QAM signals in the system link was with a bit error ratio smaller than 4.2×10 -2 based on a dual-polarization Mach-Zehnder modulation (DP-MZM) and polarization-division-multiplexing 16-ary quadrature amplitude modulation (PDM-16QAM). In summary, the system has a simple structure, a high spectrum efficiency, and a greatly enhanced transmission rate, which has great application value in the future communication network of radio over fiber.
