摘要： An optical fiber splicing device has guide grooves for aligning fiber ends. The fibers ends are held in the grooves by hold-down means including cylindrical pressing surfaces which are capable of rotating freely. Due to the free rotation, when lowering the hold-down means to hold the fiber ends, no longitudinal displacement of the fiber ends will occur and the fiber ends maintain their initial positions. The fiber ends are, after the holding operation having been completed, moved linearly, sliding in the guide grooves, an accurate linear movement being obtained from double parallelogram structures. Electrodes between which an electric arc is formed for heating the fiber ends at a splice position to fusion splice them to each other are given accurate, predetermined positions by means of adjustable positioning rings mounted to the electrodes. The splice position is illuminated by light emitted in a relatively small angle in relation to the electrode axis, this giving a very compact splicing device having a small total height.

摘要： In joining an optical fiber containing twin cores to a corresponding optical fiber of standard type having a single core and having the same outer diameter, so that a core in the twin-core fiber is aligned with the core in the standard fiber, a conventional automatic splicing machine for optical fibers is used. The twin-core fiber is placed with its cores for instance located in a vertical plane. Then the fibers are spliced in a conventional manner with an alignment of the outer surfaces of the fiber ends and during the splicing procedure or from the finished splice the lateral offset of for instance the upper core of the twin-core fiber and the single core is determined. This can be carried out by capturing an image of the fiber splice in a heated state, when the splice is performed by fusion-welding. The determined offset value then gives the offset, which is to exist between the outer surfaces of the fiber ends for providing the correct alignment of the fiber cores. Hence, the splice region of the fibers is then removed and the fibers are spliced again, but this time with a suitable, calculated offset of the outer surfaces of the fibers.

摘要： In splicing discrete individual optical fibers to a fiber ribbon cable, a fiber organizer is used for placing the loose fibers in a retainer so that they are located exactly in the same way as in a fiber ribbon cable. The retainer is a separate part which is placed, with its lids in an open position, in a lower, centrally located portion of a main part of the device. The individual fibers are inserted, one by one, in vertical slots which are aligned with each other and are located at each end of the fiber organizer. By a movable, elastic heel they are fed into horizontal, slotshaped spaces having heights or widths adapted to the diameter of the fibers and formed between lower and upper surfaces. When all fibers have been fed into the slot, the retainer lids can be swung down so that the individual fibers are securely retained in the retainer. Then upper parts at each end of the fiber organizer are opened whereby the fibers are separated from the fiber organizer, in particular from the slotshaped spaces, and the retainer can be removed together with the gripped individual fibers.

摘要： When splicing optical fibers of different kinds to each other by means of arc welding, a matching of the mode field diameters of the fibers is desired. This is accomplished by prolonging (period 55) the heating after making the splice (period 53). During the prolonged heating the hot-fiber indices of the two fiber ends are continuously determined. Either one of these indices or some suitable quantity derived therefrom is all the time compared to a threshold value and when it is reached the heating is stopped. The threshold value has been determined in a preceding stage using test fiber pieces of the same kind in a splicing operation with prolonged heating. Then, in such a threshold level determining stage in addition to the hot-fiber indices, the transmission of light is constantly measured during the heating and when it has its maximum value the corresponding hot-fiber indices are stored and used for deriving the threshold value. This method of matching mode field diameters is simple and takes a short time.

摘要： Optical fiber attenuators are produced by splicing two fiber ends by melt-fusioning. The fiber ends are initially placed with a large lateral offset and the heating of the spliced portion is continued during a long time period to completely align the fiber ends, in particular the cores (3) and claddings (2) thereof, and to make material of the fibers cores (3) diffuse (23) into the neighbouring regions of the fiber claddings. By properly choosing the extended time for prolonged heating attenuators can be produced with a good repeatability. The prolonged heating period is significantly shortened by the use of a large initial offset.
