    摘要： A conventional problem is to provide an optical module capable of being reflow mounted together with electronic components collectively, and, at the same time, securing a mechanical strength that can bear a large stress at the time of an attachment/detachment of the optical fiber. A solution to the above-mentioned problem can be attained by using an optical connector removable type optical module for reflow mounting having a fixing structure for fixing itself to a mount board, including a receptacle part installed to an optical module 19 to which an optical connector 1 is detachably connected; electric terminals 4 for reflow mounting that are arranged corresponding to lands 8 on a mount board 6; and stud parts 5 that are able to fit in fixing holes 7 on the mount board 6.

    摘要： An optical transmission module or an optical module has a receptacle attached adjacent to an optical component module or package, and a plug configured to connect vertically with the receptacle from above the module. The outer peripheral shape of the housing is designed to fit within an area of the receptacle that faces upwardly to receive the plug in an insertion direction extending vertically downwardly. In the housing of the plug, a ferrule is attached to an end of an optical fiber and a sleeve covers the optical fiber and the ferrule. A knob is used for moving the optical fiber, the sleeve and the ferrule in the lightwave propagation direction, which is transverse to the plug insertion direction. Before connecting the plug, the knob is retracted to pull the ferrule and the sleeve within the plug housing. This prevents contact of the ferrule in the plug with a mating ferrule in the optical component package that extends into the receptacle in optical alignment therewith when the plug is seated within the receptacle. The ferrule in the optical component package is connected to an optical component via another optical fiber. Upon completion of the insertion of the plug, the knob is released and the force of a spring holds the ferrules in contact with on another with sufficient force to maintain a detachable optical connection.

    摘要： An optical communication equipment includes a semiconductor laser element, an image-forming element, an optical fiber and a substrate for mounting the semiconductor laser element, the image-forming element and the optical fiber. An optical output of the semiconductor laser element is adapted to be provided to the optical fiber via the image-forming element. The image-forming element is mounted in a V-groove formed in the substrate and having a substantially “V”-shaped cross-section. A shortest distance between a light spot of the semiconductor laser element and an optical axis of the image-forming element is 1 mm at most and the image-forming element substantially satisfies the sine condition.
