摘要
针对400Gbit/s传输性能及应用问题,仿真分析了400Gbit/s不同技术方案的传输距离与频谱效率、入纤功率限制与非线性效应,结果表明,4×100Gbit/s技术可以满足骨干网1 000km以上的传输需求,而2×200Gbit/s技术则必须结合低损耗或超低损耗光纤以及新型低噪声光放大器等才可能实现。城域网、数据中心等的大带宽互联可能率先采用400Gbit/s技术,而2×200或4×100Gbit/s可以满足传输容量和传输距离的一般需求。
With respect to 400 Gbit/s transmission performances and applications,this paper simulates and analyzes the trans-mission distance and spectrum efficiency based on different technical schemes,the incident power limitation and nonlinear effects.The results show that the requirements of backbone networks for over 1 000 km transmission can be met by using the 4×100 Gbit/s technology,whereas for the same purpose,the 2×200 Gbit/s technology must be used in combination with low-loss fibers and new type of low-noise amplifiers.Metropolitan Area Networks (MAN),data centers and other large bandwidth interconnections may take the lead in adopting 400 Gbit/s,2×200 Gbit/s or 4×100 Gbit/s technologies to satisfy the general requirements for transmission capacity and distance.
