Abstract

A method for splicing a first optical fiber ribbon cable to a second optical fiber ribbon cable includes separating an end of the first optical fiber ribbon cable into loose optical fibers, and re-ribbonizing the loose optical fibers into a ribbonized end having a second pitch different from the first pitch of the original first optical fiber ribbon cable. The method further includes inserting the ribbonized end into a mass fusion splicer having the second pitch, and splicing the ribbonized end to the end of the second optical fiber ribbon cable using the mass fusion splicer.

First claim

What is claimed is:

1. A method for splicing a first optical fiber ribbon cable, comprising:
separating an end of the first optical fiber ribbon cable into a plurality of loose optical fibers, the first optical fiber ribbon cable having a first pitch;
inserting a portion of the first optical fiber ribbon cable having the first pitch and the plurality of loose optical fibers into a fiber holder, wherein the portion of the first optical fiber ribbon cable is received in a first portion of the fixture having the first pitch, and the plurality of loose optical fibers are received in a second portion of the fixture having a second pitch;
ribbonizing the plurality of loose optical fibers into a ribbonized end having the second pitch;
inserting the ribbonized end into a mass fusion splicer having the second pitch; and
splicing the ribbonized end to an end of a second optical fiber ribbon cable using the mass fusion splicer.

2. The method of claim 1 , wherein:
ribbonizing the plurality of loose optical fibers comprises placing the plurality of loose optical fibers into a fiber holder having the second pitch; and
inserting the ribbonized end into the mass fusion splicer comprises inserting the fiber holder into the mass fusion splicer.

3. The method of claim 1 , wherein the first optical fiber ribbon cable is a rollable cable having matrix material distributed intermittently along the first optical fiber ribbon cable.

4. The method of claim 3 , wherein the first optical fiber ribbon cable comprises a plurality of 200 micrometer diameter optical fibers, the first pitch is 200 micrometers, and the second pitch is 250 micrometers.

5. The method of claim 4 , wherein the second optical fiber ribbon cable comprises a plurality of 200 micrometer diameter optical fibers at a second pitch of 250 micrometers.

6. The method of claim 4 , wherein the second optical fiber ribbon cable comprises a plurality of 250 micrometer diameter optical fibers at pitch of 250 micrometers.

7. The method of claim 6 , wherein:
ribbonizing the plurality of loose optical fibers comprises placing the plurality of loose optical fibers into a first portion of a fiber holder having a pitch of 250 micrometers, and placing the plurality of 250 micrometer diameter optical fibers of the second optical fiber ribbon cable into a second portion of the fiber holder having a pitch of 250 micrometers; and
inserting the ribbonized end into the mass fusion splicer comprises inserting the fiber holder into the mass fusion splicer.

8. A method for splicing a first optical fiber ribbon cable, comprising:
separating an end of the first optical fiber ribbon cable into a plurality of loose optical fibers by stripping the end of the first optical fiber ribbon cable using a hot stripper, the first optical fiber ribbon cable having a first pitch;
cleaning the plurality of loose optical fibers;
inserting a portion of the first optical fiber ribbon cable having the first pitch and the plurality of loose optical fibers into a fiber holder, wherein the portion of the first optical fiber ribbon cable is received in a first portion of the fixture having the first pitch, and the plurality of loose optical fibers are received in a second portion of the fixture having a second pitch;
ribbonizing the plurality of loose optical fibers into a ribbonized end having the second pitch by placing the plurality of loose optical fibers into a comb structure of a fiber holder;
closing a lid of the fiber holder to clamp the plurality of loose optical fibers into the comb structure;
inserting the ribbonized end into a mass fusion splicer having the second pitch;
cleaving the ribbonized end using the mass fusion splicer; and
splicing the ribbonized end to an end of a second optical fiber ribbon cable using the mass fusion splicer.

9. The method of claim 8 , wherein:
the first optical fiber ribbon cable comprises a plurality of 200 micrometer diameter optical fibers, the first pitch is 200 micrometers, and the second pitch is 250 micrometers; and
the second optical fiber ribbon cable has a pitch of 250 micrometers.

10. The method of claim 8 , wherein the first optical fiber ribbon cable is a rollable cable having matrix material distributed intermittently along the first optical fiber ribbon cable.
