Optical fiber repair splices are effected by mating two fiber ends in an elongate open-sided housing containing a fiber-receiving capillary tube. The tube may be factory-inserted to achieve a predetermined alignment of the tube with the fiber guide-way axis of the housing. A stepping fiber passage in the housing guides the fiber end into the tube. The fiber progresses to a point in the tube's interior where the capillary track is visible through a slot in the tube. The splicer visually observes mating of the fiber ends through the slot. The tube slot also permits application of index-matching material and adhesive to the mated fiber ends. During splicing, a mounting jig holds the underside of the housing, freeing the splicer to manipulate and view the fibers.

A method for splicing an improved strength tape having longitudinally extended strands comprises the trimming or patterning of the strands of the respective ends that are to be joined so that the ends can be mated together in a meshing arrangement. The two ends are placed in a splicing tray. An adhesive film is interposed between the two ends and the splice tray is closed. The splice tray is placed in a compression molding press which applies a predetermined time-temperature-pressure treatment profile which cures the adhesive film. The resulting splice has essentially the same physical dimensions of the strength tape, and similar stiffness characteristics to that of the strength tape. Further, the strength of the splice is more than sufficient for use in a communication cable. Because the complete splice process can be completed in less than 4 to 5 minutes, the splice can be performed on-line with the use of a strength tape accumulator.

An optical fiber ribbon in which a plurality of optical fibers are held in an array has a matrix material for bonding to the fibers to form the ribbon. The matrix material has certain characteristics which serve to enhance fiber access, among which are an elastic modulus from 600 to 1200 MPa at room temperature, from 100 to 280 MPa at 100. degree. C. , and from 15 to 45 MPa at temperatures greater than 170. degree. C. The matrix material swells in ethanol more than 15% by volume within 20 minutes, and is virtually immune to the action of cleaning solvents. The matrix material has a surface tension of 20-35 mJ/m. sup. 2 as do the color coding inks which identify the fibers.
