摘要： PROBLEM TO BE SOLVED: To provide a masking apparatus that has no possibility of damaging an optical fiber and that facilitates reuse. SOLUTION: The apparatus has a structure of elastically clamping, with clamp members 15, 16, a lower member 12 that has a fiber storing groove 12a and upper members 13, 14 that are each placed over the front part and the rear part of the lower member 12. The bare fiber 1a of an optical fiber 1 is housed in the fiber storing groove 12a, with a lens part 1c at the tip end projected. Thus, vapor deposition of an anti-reflection film is performed by masking areas other than the lens part 1c of the bare fiber 1a. Because of the structure of holding the bare fiber 1a with the upper and lower members, it is different from the conventional structure of inserting an optical fiber into the optical fiber hole of a ferrule, hardly causing damage when the bare fiber 1a is inserted. The members 12, 13, 14 are each separable and therefore easily cleaned, the masking apparatus can be easily reused. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：要解决的问题：提供一种不会损坏光纤并且有利于再利用的掩蔽装置。解决方案：该装置具有弹性夹持的结构，具有夹紧构件15,16，具有光纤存储槽12a和上部构件13,14的下部构件12，下部构件12分别放置在前部和后部光纤1的裸光纤1a容纳在光纤存储槽12a中，其顶端突出有透镜部分1c。因此，通过掩蔽裸光纤1a的透镜部1c以外的区域来进行防反射膜的蒸镀。由于将裸光纤1a保持在上部和下部构件上的结构不同于将光纤插入到套圈的光纤孔中的传统结构，当裸光纤1a插入时几乎不会损坏。构件12,13,14各自是可分离的，因此易于清洁，掩蔽装置可以容易地重复使用。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To facilitate the manufacture of a thermal-diffusion expanded core (TEC) optical fiber. SOLUTION: A composite optical fiber being a TEC optical fiber is constituted by splicing a plurality of optical fibers 22, 23, 24 and 25 whose core diameters are different in the order in which core diameters become larger gradually. The manufacture of the composite optical fiber is easier than that of the TEC optical fiber in which the core is expanded in a tapered manner. Moreover, when performing an optical connector splicing by attaching an optical connector to the the composite optical fiber 21, since the diameter of the core 25a in the splicing end face 21a is expanded, an influence of deviation in a position is small and splicing loss is small. Moreover, since energy per an unit area of light emitted from the end face becomes small, a problem in which scratched parts and dust of the end face are burned by strong light and the state of the end face is deteriorated can be avoided.

摘要翻译：要解决的问题：为了促进热扩散膨胀芯（TEC）光纤的制造。解决方案：作为TEC光纤的复合光纤通过将芯直径逐渐变大的次序的芯径不同的多根光纤22,23,24,25进行拼接而构成。复合光纤的制造比其中芯以锥形膨胀的TEC光纤的制造容易。此外，当通过将光连接器附接到复合光纤21进行光连接器拼接时，由于拼接端面21a中的芯25a的直径扩大，位置偏差的影响小，拼接损耗为小。此外，由于从端面发射的光的单位面积的能量变小，所以可以避免由强光烧结端面的刮伤部分和灰尘，并且端面的状态劣化的问题。版权所有（C）2006，JPO＆NCIPI
