Y10T285 多芯光纤理论传输容量Y10T285 Multi-core Fiber Theoretical Transmission Capacity
➀ 目前大容量光纤通信单纤容量达到约32T,理论研究扩展到O、E、S、L波段及部分U波段,部分探索达到400T左右。➁ 全频谱范围内的单纤理论容量约为580T。➂ 基于多芯光纤的SDM被认为是进一步扩展单纤容量的可行技术,ITU已启动相关研究。➃ 由于重量和复杂性问题,弱耦多芯光纤采用标准或减包层直径是产业趋势。➄ 弱耦多芯光纤中的芯间串扰是一个重大问题,会降低有效频谱效率。➅ NICT和微软合作,为多芯光纤的最佳芯数提供了数据,建议4芯是达到高频谱效率的最佳选择。➀ Current high-capacity optical communication reaches a single fiber capacity of about 32T in the C+L band. Theoretical research extends to the O, E, S, L, and partial U bands with ultra-wide spectral applications, with some explorations reaching up to 400T. ➁ The total theoretical capacity of a single fiber using all the spectrum is around 580T. ➂ Multi-core fiber-based SDM is considered a feasible technology to further expand single-fiber capacity, and ITU has initiated research on this. ➃ Weakly coupled multi-core fibers with a standard or reduced cladding diameter are the industry trend due to weight and complexity issues. ➄ Inter-core crosstalk is a significant issue in weakly coupled multi-core fibers, reducing effective spectral efficiency. ➅ NICT and Microsoft have collaborated to provide optimal numbers for the number of cores in multi-core fibers, suggesting that 4 cores are the best choice for achieving high spectral efficiency.
