    • To provide an optical connector that enables the reduction in the number of parts and can be easily attached to an optical cable, a concave portion 18 for a ferrule is formed in a plug housing 6, and a ferrule 3 is inserted from the side of a collar portion 10 into the concave portion 18 for a ferrule. A hook portion 28 for a ferrule is provided in a protruding condition inside the plug housing 6. The collar portion 10 is guided by the hook portion 28 for a ferrule, which has been elastically deformed, and moves toward a bottom surface 26 of the concave portion 18 for a ferrule. Where the collar portion 10 reaches a space between the bottom surface 26 and the hook portion 28 for a ferrule, the hook portion 28 for a ferrule is elastically restored. Therefore, even if the collar portion 10 tries to move toward an opening 24 of the concave portion 18 for a ferrule, the collar portion is locked by the hook portion 28 for a ferrule and the movement is inhibited. Thus, in the plug-type optical connector 1, the ferrule 3 can be positioned by inserting into the plug housing 6 and moving.

    • An optical module is configured such that it is not susceptible to fine particulate matter when an optical fiber is inserted into a fiber insertion hole thereof. The optical module is also configured to prevent any reduction in the optical coupling efficiency and degradation of anti-noise properties with the optical fiber. The optical module includes: a ferrule, having the fiber insertion hole formed on an end surface on which an electrical circuit is formed; a photoelectric conversion element, connected to the electrical circuit and facing the fiber insertion hole; and an optical fiber, optically coupled directly with the photoelectric conversion element. The optical fiber has a glass fiber and a protective coating, and is aligned with the insertion hole with the protective coating interposed therebetween. The optical fiber is retained in the insertion hole with the glass fiber not in contact with the insertion hole.
    • 光学模块被配置为使得当光纤插入其光纤插入孔中时,其不易受细颗粒物质的影响。 光学模块还被配置为防止光耦合效率的任何降低和光纤的抗噪声特性的降低。 光学模块包括:套圈,其具有形成在其上形成电路的端面上的光纤插入孔; 光电转换元件,连接到电路并面向光纤插入孔; 以及与光电转换元件直接光耦合的光纤。 光纤具有玻璃纤维和保护涂层,并且与插入孔对准,其间具有保护涂层。 光纤保持在插入孔中,玻璃纤维不与插入孔接触。
