摘要： It is an object of the present invention to provide a light sending and receiving module by a ferrule, a connecting device of the light sending and receiving module and a method of manufacturing the light sending and receiving module characterized in that: the light sending and receiving module is interposed between the butting faces of the optical fibers without embedding an optical filter; deterioration of the optical characteristic can be prevented by eliminating a gap between the optical fiber and the optical filter; the number of ferrules is decreased so as to reduce the manufacturing cost; and further the size can be reduced by omitting an adapter. According to the present invention, there are provided a ferrule joining member (1A), in which a portion or all of the circumferential face of an optical fiber (4) is exposed from an end portion of the ferrule in which the optical fiber (4) is embedded, and a guide sleeve (2A) for positioning into which the ferrule joining member (1A) is inserted. When end faces of the optical fibers (4) are butted to each other via an optical filter (5) so as to conduct light branching, the optical fibers (4) are optically coupled to each other. Due to the above structure, no gaps are formed between the optical fiber (4) and the optical filter (5). Therefore, the occurrence of irregular reflection can be prevented.
摘要翻译：本发明的目的是提供一种套圈的发光和接收模块，发光和接收模块的连接装置及其制造方法，其特征在于：发光和接收模块插入在光纤的对接面之间，而不嵌入滤光器; 通过消除光纤和滤光器之间的间隙可以防止光学特性的劣化; 套圈的数量减少，从而降低制造成本; 并且还可以通过省略适配器来减小尺寸。根据本发明，提供了一种套圈接合构件（1A），其中光纤（4）的圆周面的一部分或全部从套圈的端部露出，其中光纤（4））和用于定位的导套（2A），套圈接合构件（1A）插入其中。当光纤（4）的端面通过滤光器（5）彼此对接以便进行光分支时，光纤（4）彼此光学耦合。由于上述结构，在光纤（4）和滤光器（5）之间不形成间隙。因此，可以防止发生不规则反射。
