摘要
文章总结了我国在高端光纤技术方面的研究进展: 400 Gbit/s用高端光纤技术包括超低损耗光纤技术和大有效面积光纤技术, 我国研制的超低损耗光纤在1 550 nm的衰减为0.167 dB/km, 达到了国际先进水平; 但大有效面积光纤在1 550 nm的有效面积仅为130 μm2, 与国际的150 μm2有一定差距; 在Tbit/s大容量空分复用光纤方面, 我国进行了少模光纤、多芯光纤和轨道角动量光纤的基础探索研究, 与国际水平相当。研究结论表明, 我国在大容量通信用高端光纤技术方面达到了国际先进水平, 这为我国下一代高速光纤通信技术探索了新的可能性。
Abstract
In this paper, the research progress of high-end optical fiber technology in our country is analyzed and summarized. The high-end optical fiber technologies for 400 Gbit/s system include ultra-low-loss optical fiber and large-effective-area optical fiber. In China, the attenuation for ultra-low-loss optical fiber has achieved 0.167 dB/km, which has reached the international advanced level. The effective area at wavelength of 1 550 nm for large-effective-area optical fiber has achieved 130 μm2, which has a certain gap compared with the international level of 150 μm2. Based on the research of Tbit/s large capacity Space-Division-Multiplexing (SDM) optical fiber, the basic researches of the multi-core optical fiber and Orbital Angular Momentum (OAM) fiber are carried out and have achieved great progress. The research results show that the high-end optical fiber technologies for large-capacity optical communication have reached the international advanced level, which bring a new possibility for the next generation of high-speed optical fiber communication technology.
