英国巴斯大学和Blaze光电子公司的研究人员研制出新式低损耗光子带隙光纤。它的衰减为1.72dB／km,表明对以前报道过的最低损耗(13dB／km)光纤有显著改进。这项进展使新光纤的吸收向普通远程通信光纤的要求(0.15dB／km)迈进了一大步,显示
Researchers at the University of Bath and Blaze Optoelectronics in the UK have developed new low loss photonic bandgap fibers. Its attenuation is 1.72 dB / km, indicating a significant improvement over the previously reported minimum loss (13 dB / km) fiber. This progress made the absorption of new optical fibers a major step toward the requirements of ordinary telecommunication fibers (0.15 dB / km)
