贝尔研究所的科学家们在“自然”杂志上撰文揭示了使美国朗讯科技能以接近理论极限的透明度制造光纤的细节。目前以全波光纤进入市场的上述光纤在现有的两个传输窗口 ( 1.3μm和 1.55μm)之间的整个波长范围都具有很低的损耗。其奥秘是采用一种拥有专利权的纯化工艺 ,这种工艺?
The Bell Institute scientists in Nature wrote an article that sheds light on the details of how Lucent Technologies can make optical fiber with transparency close to the theoretical limit. The optical fibers currently marketed as full-wave optical fibers have very low losses over the entire wavelength range between the two existing transmission windows (1.3 and 1.55 m). The secret is to use a patented purification process, this process?
