摘要： PURPOSE:To enable the prevention of reflection without connection loss by polishing obliquely the end face of an optical fiber connector except the half or less of the ferrule end face. CONSTITUTION:The ferrule 6 of an optical fiber connector consists of an optical fiber cable 7 and an optical fiber positioning key 9 and its end 10 is polished together with an optical fiber 8 except the half or less of the surface 11 at a right angle to the optical axis obliquely at an angle theta. The central axis 12 of the polished surface is rotated by alpha deg. relatively to the key 9. Since the gap G of the fiber 8 is obliquely polished except the plane at the ferrule end, the gap can be made smaller than in the prior art wherein the ferrule end is sloped over the entire surface. The connection loss of light at the gap G is thus decreased. It is possible to evaluate the gap-component of the optical fiber due to the finishing by polishing by measuring the distance from the center of the fiber up to the ridgeline where the slope and the end face intersect and the angular deviation of both faces.
摘要翻译：目的：通过倾斜地抛光光纤连接器的端面，除了套圈端面的一半以下，能够防止反射而没有连接损失。构成：光纤连接器的套管6由光纤电缆7和光纤定位键9组成，其端部10与表面11的一半以下的光纤8一起被抛光，直到与光轴以角度θ倾斜。抛光表面的中心轴线12旋转α度。由于光纤8的间隙G除了套圈端部的平面外倾斜抛光，所以可以使间隙小于现有技术中的间隙，其中套圈端部在整个表面上是倾斜的。因此，间隙G处的光的连接损失减小。可以通过测量从光纤的中心到斜面和端面相交的棱线之间的距离以及两个面的角度偏差来评估光纤的间隙分量。

摘要： PURPOSE:To make plugging-in easy and to improve safety against the oscillation at the time of transport, by making a rackside connector freely and loosely movable only in the time of plugging-in. CONSTITUTION:If a panel 2 is moved in order to couple an optical connector 3 on a rack 1 side and an optical connector 4 on the panel side by plugging-in, the leaf spring 11 for fixing the connector 3 of the rack 1 is pressed by the pawl member 13 of the panel 2. Then, the connector 3 is made freely and loosely movable in the direction at right angles to the plugging-in direction, and the coupling of the connectors 3, 4 is easily and surely accomplished. The connector 3 is thus fixed to the rack 1 by means of the spring 11 in the stage of transporting the rack 1 without coupling the connectors 3, 4, whereby the safety against the oscillation at the transport is improved.

摘要： PURPOSE:To allow plugs of simple structure to be coupled together to face each other while matched and positioned accurately by linking both side walls having plug guide grooves in internal surfaces to each other through a leaf spring, and pressing them outward by plugs when those plugs are attached. CONSTITUTION:In plugs 12 to be coupled, plural optical fibers 20 are mebedded. On both side surfaces of each plug 12, semicircube cylindrical reference surfaces 19 are formed. An adapter 11 into which both plugs 12 are inserted consists of both side walls 16 and a leaf spring 18 for connecting both side walls 16 and has guide grooves for guiding the reference surfaces 19 of the plugs 12 in the internal surface. The leaf spring 18 of the adapter 11 is curved when no plug 12 is inserted and the actual width of the adapter 11 is less than the width Wp of the plugs 12. Therefore, the reference surfaces 19 of the plugs 12 are held while pressed elastically against the internal surfaces of the guide grooves 17.

摘要： PURPOSE:To ensure the connection with the mirror finished end face of an optical fiber, by forming a recessed end face having a slight level difference on a ferrule end face and giving a cut to the optical fiber fixed to the ferrule along the recessed end face to cut the optical fiber. CONSTITUTION:A recessed end face B tapering toward the center part is given by a sharp cutter 33 to an optical fiber element 32 fixed to the ferrule 31 and along a parallel end face B. Thus the optical fiber 32 is cut. The core part is cut with a substantial mirror surface and has a level difference (l) compared with the face A of the ferrule 31. The ferrule 31 is loaded to an adaptor 3 and a coupling nut 4, and the optical fibers are connected together with a slight space.

摘要： PURPOSE:To eliminate the variance of a lens holding force and a shortage of the holding force by providing plural pin holes opening to the inside face of a taper hole of a metallic holder radially with respect to the axial line of this taper hole and fixing and holding a spherical lens in the taper hole by tip parts of pins fixed to individual pin holes. CONSTITUTION:A taper hole 21 for holding a spherical lens 20 is provided in the center part of a metallic holder 16 with the same center as the axial line, and four pin holes 24 are provided radially with respect to this axial line. Since the axial line of each pin hole 24 is deflected to the taper large-diameter side off a center O1 of the spherical lens 20 abutted on the inside face of the taper hole 21, a tip part 26 of a pin 25 screwed into each pin hole 24 is projected to the inside of the taper hole 21 and is brought into contact with the surface of the spherical lens 20 to prevent the spherical lens 20 from slipping to the large- diameter side of the taper hole 21. Since the tip part 26 of each pin 25 is formed hemispherically, flaws on the surface of the spherical lens 20 are prevented.

摘要： PURPOSE:To enhance the reliability and reduce the number of parts by a method wherein the tip of a cylinder part of a housing is bent toward the center and then caulked. CONSTITUTION:Two or more of slits 10b are provided in the axial direction to the cylindrical part 10a whereto the titled element and the bush of the housing 10 are inserted, and said element 11 and said bush 12 are inserted. Thereafter, the tip 10c of the cylindrical part is bent toward the center and then caulked, and the element 11 is fixed via bush 12. The fixture of the element is enabled only by caulking, therefore the number of parts is reduced, and then the reliability can be enhanced. Besides, caulking is performed only by a specific claw at the time of assembly, and the characteristic of the element is checked in the state. If defective, the claw part is opened by utilizing the gap between the bush and the claw part, thereby exchanging the element.

摘要： PURPOSE:To obtain an inexpensive optical semiconductor module by using a heat-shrinkable tubing to form a lens and a ferrule arraying sleeve into one body. CONSTITUTION:A semiconductor module is composed of an optical semiconductor element 10, a spherical lens 11, a housing 12, a ferrule arraying sleeve 13, a holding screw 14 and a position control screw 15 for element 10. The lens 11 is held between tools 20 and 21, and a heat-shrinkable tubing 22 is put over the lens 11 and heated. Thus the tubing 22 shrinks to adhere to the lens 11 and the tool 21. Then the tools 20 and 21 are removed, and a ferrule arraying sleeve 23 holding the lens 11 is obtained. The cost is reduced since the sleeve 13 is simply formed with the tube 22.

摘要： PURPOSE:To reduce optical coupling loss and cost and to facilitate fitting to an optical fiber by forming a recessed part for an adhesive overflow at the pivotally supporting part of the opposing end surfaces of a ferrule and preventing adhesive from sticking to the end surface of an optical fiber element wire. CONSTITUTION:The recessed groove 15 is formed in the end surface of the ferrule 3. The end surface 2' of the optical fiber element wire 2 crosses the axial center and a specular surface. When the fiber 1 is inserted into the axial hole of the ferrule 3, its end surface is 10-50mum deeper than the end surface 6. Their outer circumferential surfaces are coated with adhesive (exposy resin) 7 which has good transparency and a refractive index close to that of the core and both are fixed together. A part of the adhesive in pores 5 is forced out toward the side of the end surface 6 by the end surface 2' through the sliding motion of the element wire 2 to stick to the end 2' partially, but the majority of them sticks to the bottom surface of the recessed groove 15 and solidified. Further, an elastic solid filter 16 such as epoxy resin is provided to the recessed groove 15 at the circumferential edge. Therefore, the end surface 2' never strikes the opposing end surface 2'.
