摘要： PROBLEM TO BE SOLVED: To provide an optical fiber ribbon splitting tool which does not bend optical fibers during splitting work.SOLUTION: An optical fiber ribbon splitting tool 1 splits an intermittently fixed optical fiber ribbon having intermittent inter-optical fiber connection parts 3, to single optical fibers and comprises a linear rail 5 and a splitting tool body 6 slidable on the rail. The splitting tool body 6 includes a body base 8 and a lid part 9, and an optical fiber ribbon is inserted between the body base 8 and the lid part 9. The lid part 9 is provided with a coil spring (splitting action member) 21. When the splitting tool body is slid to locate the coil spring in a non-connection region d having no inter-optical fiber connection parts 3 in one position in a lengthwise direction of the optical fiber ribbon, a wire material 21a of the coil spring enters between optical fibers. When the splitting tool body is slid furthermore, respective connection parts 3 are torn by the wire material 21a to split the optical fiber ribbon to single optical fibers. Since a bending force causing optical loss on optical fibers does not act during splitting work, the optical fiber ribbon can be split to single optical fibers in a hot-line state.
摘要翻译：要解决的问题：提供一种在分离工作期间不弯曲光纤的光纤带分割工具。解决方案：光纤带分割工具1将具有间断的光纤间连接部分3的间歇固定的光纤带分割成单个光纤，并且包括可在轨道上滑动的直线导轨5和分割工具主体6。分割工具主体6包括主体基部8和盖部9，并且在本体基部8和盖部9之间插入光纤带。盖部9设置有螺旋弹簧（分离动作部件）21 当分割工具主体滑动以将螺旋弹簧定位在光纤带长度方向上一个位置上没有光纤间连接部分3的非连接区域d时，螺旋弹簧的线材21a 进入光纤之间。当分割工具体进一步滑动时，各个连接部分3被线材21a撕裂，以将光纤带分裂成单根光纤。由于在分光作业时光纤上产生光损耗的弯曲力不起作用，所以光纤带可以在热线状态下分裂为单根光纤。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a dielectric multilayer film filter element in which an optical component having the dielectric multilayer film filter element nippedly held between a couple of collimator lenses can be small-sized by reducing a reflection attenuation quantity and a ripple of the optical component. SOLUTION: The dielectric multilayer film filter element 4 has a 1st end surface slanted to an optical axis and a 2nd end surface parallel thereto. Consequently, reflected light is at a different angle from the optical axis on the 1st end surface and the reflection attenuation quantity is reducible. On the 2nd end surface, primary transmitted light and high-order transmitted light which is secondary light or later are different in projection position and further the high-order transmitted light which is the secondary light or later is attenuated through an AR coat. Consequently, interference can be deterred and the amplitude of a ripple is reducible. Furthermore, collimator lenses 3 and 5 and the filter element 4 can be arranged nearly on a straight line, so the optical component can be made small-sized. COPYRIGHT: (C)2004,JPO&NCIPI
摘要翻译：要解决的问题：为了提供一种电介质多层膜滤光元件，其中通过减少反射衰减量和纹波，可以将被夹持在几个准直透镜之间的电介质多层膜滤光元件的光学部件小型化的光学部件。电解质多层膜过滤元件4具有向光轴倾斜的第一端面和与其平行的第二端面。因此，反射光与第一端面上的光轴成不同的角度，反射衰减量可减少。在第二端面上，作为二次光或以后的一次透射光和高次透射光在投影位置上不同，另外，二次光以上的高次透射光通过AR涂层衰减。因此，可以阻止干扰并且可以减小纹波的幅度。此外，准直透镜3和5以及滤光元件4可以几乎布置在直线上，因此可以使光学部件小型化。版权所有（C）2004，JPO＆NCIPI

As the plurality of connector holders 6 for holding the individual optical connectors 4 are connected with each other via thin wall hinge parts 7 to form a lateral line, the whole holder can be easily curvedly rounded. Not only confusion of optical cables is less likely to occur, but also the optical cable can be easily passed through an optical cable access hole provided in a housing of an optical apparatus, thus facilitating wiring work of the optical cables with optical connectors. The optical connector section of the optical cable 2 with the optical connector can be easily held by the constricted part 8a of the projection 8.
