| 摘 要： | 采用全合成预制棒制造法（VAD＋OVD）和改进的G.652.D光纤拉制法制造光纤.研究了工艺中光纤芯径的大小、第一包层的厚度、芯包折射率差、芯包比等参量与光纤弯曲性能的关系,并据此制作了几种超细低水峰抗弯损光纤.该光纤的裸光纤直径约80 μm,涂覆后成品光纤直径约140 μm,当弯曲半径不小于7.5 mm时,能够在1 260～1 625 nm整个波段内满足DWMD的传输要求.

| Abstract: | A novel refractive index profile for low bending loss fiber was proposed and the influence on the fiber bending loss was analyzed in detail as a function of various factors,including core diameter, first cladding thickness,difference between core-cladding refractive indices,and ratio of core to cladding diameter.By utilizing Complete Synthetic Technology (VAD+OVD) for the fabrication of optical fiber preforms,combining with a modified fiber drawing technique,a series of super-fine low water-peak bend-resistant optical fibers were fabricated and tested,with a naked diameter as small as 80 μm and coated diameter of 140 μm.The fiber is capable of meeting the standard transmission requirement when being bended to a radius as low as 7.5 mm. |
