This work proposes and tests a simplified coherent uplink architecture for ultra-dense coherent analog mobile Fronthaul with phase noise cancellation based on single sideband modulation of a dual-EML. Results show optical channel spacings of only 1.5 GHz and error-free signal recovery with Δν\Delta \nu Tb = 1.2% and 3% with reaching power as low as −46dBm for 100 Mbit/s and −38 dBm for 1 Gbit/s using QPSK modulation.

具有 D-EML 发射器和相位噪声鲁棒接收器的相干 UD-WDM RoF 前传网络


这项工作提出并测试了一种用于超密集相干模拟移动前传的简化相干上行链路架构，具有基于双 EML 的单边带调制的相位噪声消除功能。结果显示，光通道间隔仅为 1.5 GHz，并且在 Δν\Delta \nu Tb = 1.2% 和 3% 时实现无差错信号恢复，100 Mbit/s 的功率低至 -46dBm，1 Gbit/s 的功率低至 -38 dBm使用QPSK调制。
