使用新型循环移频器 (RFS) 设备生成由连续 4,104 个频谱重叠子载波组成的 1-Tb/s 单通道相干光 OFDM (CO-OFDM) 信号。 RFS 使用具有卓越平坦度和音噪比 (TNR) 的单激光器产生 320.6 GHz 宽频谱。 1-Tb/s CO-OFDM 信号由 36 个不相关的正交频带组成，这些正交频带是通过将 RFS 的延迟调整为整数个 OFDM 符号周期而实现的。在没有拉曼放大和色散补偿的情况下，通过600公里SSMF光纤传输后，频谱效率为3.3bit/s/Hz的1Tb/s CO-OFDM信号被成功接收。
A 1-Tb/s single-channel coherent optical OFDM (CO-OFDM) signal consisting of continuous 4,104 spectrally-overlapped subcarriers is generated using a novel device of recirculating frequency shifter (RFS). The RFS produces 320.6-GHz wide spectrum using a single laser with superior flatness and tone-to-noise ratio (TNR). The 1-Tb/s CO-OFDM signal is comprised of 36 uncorrelated orthogonal bands achieved by adjusting the delay of the RFS to an integer number of OFDM symbol periods. The 1- Tb/s CO-OFDM signal with a spectral efficiency of 3.3 bit/s/Hz is successfully received after transmission over 600-km SSMF fiber without either Raman amplification or dispersion compensation.
