Abstract
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.
