Abstract

A splice for holding the ends of optical fibers in end to end relationship includes a pair of sections having mating planar surfaces in engagement. One of the surfaces has an axially aligned groove facing the other surface to form an opening. The fiber receiving member comprises an elastomeric material of sufficient resilience to permit the opening to expandably receive optical fibers dimensioned larger than the opening. A sleeve is mounted about the receiving member for holding the sections in assembled relationship.

Claims

1. A splice for holding the ends of optical fibers in end to end relationship comprising a fiber receiving member having an external polygonal shaped surface and formed by a pair of sections, said sections having complimentary and mating planar surfaces in engagement, only one of said planar surfaces having an axially aligned groove therein and facing the other of said planar surfaces to form an opening therewith, said fiber receiving member comprising an elastomeric material of sufficient resilience to permit said opening to expandably receive optical fibers dimensioned larger than said opening, and a cylindrically shaped sleeve mounted about said receiving member for holding said sections in assembled relationship.

2. A splice according to claim 1 wherein said groove is a V-shaped groove.

3. A splice according to claim 2 wherein said opening has a substantially triangular cross section for receiving fibers having a substantially circular cross section.

4. A splice according to claim 3 wherein said opening includes a fiber junctioning region, said opening extends from said junctioning region along a straight path toward respective ends of said receiving member.

5. A splice according to claim 4 wherein said opening flares outwardly from a position interior the fiber receiving member to respective ends thereof.

6. A splice according to claim 1 wherein said mating surfaces extend from one corner of the external surface through the axial center of the receiving member to another corner thereof.

7. A splice according to claim 1 wherein said sleeve has a radius of curvature smaller than the distance from the axial center of the receiving member to a corner thereof.

8. A splice according to claim 7 wherein said receiving member comprises a transparent material.
