摘要
我们开发了一种模场直径在9.2μm(1310nm)附近,并且满足ITU-T G.657 A1标准的低宏弯损耗性能的200μm涂层直径光纤。这种光纤的折射率剖面简单,包括芯层、下陷内包层和外包层,特别适合大规模生产。经试验证实,这种光纤具有良好的熔接特性和微弯曲损耗,特别适合用于色环光纤和并带光纤。
We developed a new kind of 200μm-coated diameter optical fiber with a mode field diameter of around 9.2μm at a wavelength of 1310 nm,and with a low macro-bending loss satisfying ITU-T G.657 A1.The refractive index profile of this optical fiber is simple,including a central core,a depressed inner cladding,and an outer cladding,it is suitable for mass production.Experiments show that the fiber has good splice characteristics and micro-bending loss,and is especially suitable for ring-marks and fiber ribbon.
