Abstract

The present invention is related to a method of assembling a transition assembly and a transition assembly. The method described herein may comprise stripping a plurality of fibers at an end of a cable; splicing the plurality of fibers from the cable with a plurality of pigtails; and protecting the bare fiber with a cover. The transition assembly may comprise a fiber protection part and a cover that covers the fiber protection part. The fiber protection part may have openings.

First claim

The invention claimed is:

1. A method of assembling a transition assembly, the method comprising:
stripping a plurality of fibers at an end of a cable;
splicing the plurality of fibers from the cable with a plurality of pigtails;
protecting the plurality of fibers with a fiber protection part, the fiber protection part comprising openings; and
covering the spliced fibers and the fiber protection part with a cover, wherein the cover comprises an over molded polymer that solidifies inside the openings of the fiber protection part.

2. The method according to claim 1 , wherein
the openings of the fiber protection part allow for intimate contact between a polymer and the plurality of fibers.

3. The method according to claim 2 , wherein
the over molded polymer provides intimate contact with the plurality of fibers.

4. A transition assembly, the assembly comprising:
a cable;
a plurality of fibers inside the cable;
a plurality of pigtails;
a fusion splice configured to combine the plurality of fibers and the plurality of pigtails;
a plurality of connectors configured to connect the plurality of pigtails on an end opposite the fusion splice;
a fiber protection part configured to protect the splice holder, the plurality of pigtails, and the plurality of fibers;
a cover configured to cover the plurality of pigtails, the fiber protection part, and the plurality of fibers; and
a plurality of metal rods being combined with the fiber protection part inside the cover for securing and protecting the fiber protection part.

5. The assembly according to claim 4 , wherein
the fiber protection part comprises openings.

6. The assembly according to claim 5 , wherein
the cover comprises an over molded polymer that solidifies inside the openings of the fiber protection part and protects the fibers.

7. A transition assembly, the assembly comprising:
a cable;
a plurality of fibers inside the cable;
a plurality of pigtails;
a fusion splice configured to combine the plurality of fibers and the plurality of pigtails;
a plurality of connectors configured to connect the plurality of pigtails on an end opposite the fusion splice;
a fiber protection part configured to protect the splice holder, the plurality of pigtails, and the plurality of fibers; and
a cover configured to cover the plurality of pigtails, the fiber protection part, and the plurality of fibers, wherein
the fiber protection part comprises openings, and
the cover comprises an over molded polymer that solidifies inside the openings of the fiber protection part and protects the fibers.
