<p>A device (10) for splicing multiple optical fibers includes a splice element (18) having two plates with fiber receiving V-grooves formed in the inner surface of one of the plates, and a splice body having a wedge (22) to actuate the splice element by clamping the plates together. The splice body includes a jacket (14) and a cap (16), there being a slot (26) in the jacket (14) for receiving the splice element (18) and a cavity adjacent the slot for receiving the wedge (22). The cavity has a ramped surface which causes the wedge (22) to move toward the splice element and clamp the plates as the wedge is moved forward on the ramp surface. A tongue (24), formed integrally with the cap (16), is preferably interposed between the wedge (22) and the splice element (18) to prevent deformation of the plates which might result from direct contact between the plates and the wedge (22) as it slides forward. The wedge (22) and tongue (24) advantageously apply the clamping force only at the centre of the splice element, allowing the ends thereof to remain slightly flexed, thereby providing gradual clamping of the fibers which reduces signal loss.</p> |
