Coherent optical single-carrier frequency-division-multiplexing (CO-SCFDM) is a promising candidate for future high-speed long-haul optical fiber transmission system. Being a modified form of coherent optical orthogonal frequency division multiplexing (CO-OFDM), the CO-SCFDM can inherit the advantages such as low computation complexity and high flexibility, while suffers less nonlinear impairment due to much lower peak-to-average power ratio (PAPR). In this paper, we experimentally demonstrate 1.08 Tb/s polarization-division multiplexing (PDM) CO-SCFDM transmission over 3170 km standard single-mode fiber (SSMF) with Erbium-doped fiber amplifier (EDFA) only. The back-to-back and nonlinear transmission performances for CO-OFDM and CO-SCFDM are also compared.
相干光单载波频分复用（CO-SCFDM）是未来高速长距离光纤传输系统的一个有前途的候选方案。作为相干光正交频分复用（CO-OFDM）的一种改进形式，CO-SCFDM可以继承诸如低计算复杂度和高灵活性等优点，同时由于峰均功率比（PAPR）低得多而遭受的非线性损伤较小。在本文中，我们仅使用掺铒光纤放大器（EDFA）在3170公里标准单模光纤（SSMF）上通过实验演示了1.08Tb/s偏振分复用（PDM）CO-SCFDM传输。还比较了CO-OFDM和CO-SCFDM的背对背和非线性传输性能。
