研究了1.2Tb/s无保护间隔相干光正交频分复用信道在超大面积光纤（ULAF）上的传输性能，并采用两种不同的放大方案.分别采用混合拉曼/掺铒光纤放大器和全拉曼放大方案实现了52和72个100 km ULAF跨距的超长距离传输。讨论了在这两种放大方式下的光信噪比性能和信号对光纤非线性的容忍度。
We investigate the transmission performance of a 1.2-Tb/s no-guard-interval coherent optical orthogonal frequency-division-multiplexing channel over ultra-large-area fiber (ULAF) using two different amplification schemes. Ultra-long-haul transmissions over 52 and 72 100-km ULAF spans are demonstrated using hybrid Raman/erbium-doped-fiber amplifier and all-Raman amplification schemes, respectively. The optical signal-to-noise-ratio performance and the signal tolerance to fiber nonlinearity under these two amplifications are discussed.
