Abstract

An example single-station splicing unit is provided that includes a housing, an alignment element, a first electrode, and a second electrode. The housing includes an interior space and at least one cover configured to be interlocked with the housing to enclose the interior space. The alignment element is disposed within the interior space of the housing. The first electrode is disposed on one side of the housing, and the second electrode is disposed in the housing on an opposing side from the first electrode and in a facing relationship with the first electrode. The housing is configured to receive fibers in an opposing and abutting relationship to splice the fibers, and the housing remains secured to the fibers after splicing.

First claim

The invention claimed is:

1. A single-station splicing unit, comprising:
a housing including an interior space, and at least one cover configured to be interlocked with the housing to enclose the interior space;
an alignment element removably disposed within the interior space of the housing;
a first electrode disposed on one side of the housing; and
a second electrode disposed in the housing on an opposing side from the first electrode and in a facing relationship with the first electrode;
wherein the housing is configured to receive fibers in an opposing and abutting relationship to splice the fibers;
wherein the alignment element is configured to support a cladding section of the fibers, and interlocking of the at least one cover with the housing is configured to radially secure the cladding section of the fibers against the alignment element; and
wherein the housing remains secured to the fibers after splicing.

2. The single-station splicing unit of claim 1 , wherein the housing includes alignment protrusions extending from a bottom surface of the housing, and the alignment element includes complementary notches configured to engage with the alignment protrusions of the housing to orient the alignment element within the housing.

3. The single-station splicing unit of claim 1 , wherein the housing includes first and second upwardly directed extensions protruding from a bottom surface of the housing, the first and second upwardly directed extensions configured to support a coated section of the respective fibers.

4. The single-station splicing unit of claim 3 , wherein an uppermost point of each of the first and second upwardly directed extensions includes a groove formed therein and extending the length of the first and second upwardly directed extensions.

5. The single-station splicing unit of claim 4 , wherein the groove is configured complementary to an outer diameter of the coated section of the respective fibers.

6. The single-station splicing unit of claim 1 , wherein the at least one cover includes first and second covers configured to close over and crimp a coated section of the respective fibers at proximal and distal ends of the housing.

7. The single-station splicing unit of claim 6 , wherein the at least one cover includes a third cover disposed between the first and second covers, the third cover configured to close over and seat the cladding section of the respective fibers within a groove formed in the alignment element.

8. The single-station splicing unit of claim 6 , wherein each of the first, second and third covers is pivotably connected to a main body section of the housing with a hinge.

9. The single-station splicing unit of claim 1 , wherein first and second outer walls of the housing include a slot formed therein, the slots configured to slidably receive the respective first and second electrodes.

10. The single-station splicing unit of claim 9 , wherein each slot includes a first opening facing outwardly away from the interior space of the housing, and a second opening facing inwardly towards the interior space.

11. The single-station splicing unit of claim 10 , wherein a body of the first and second electrodes is exposed through the first opening formed in the slots of the housing for electrical contact with contacts of a fusion splicer.

12. The single-station splicing unit of claim 10 , wherein a pointed extension of the first and second electrodes extends into the interior space of the housing through the second opening formed in the slots of the housing.

13. The single-station splicing unit of claim 1 , wherein the alignment element includes an elongated body with a notched area creating a space aligned with a position of the first and second electrodes.

14. The single-station splicing unit of claim 13 , wherein the alignment element includes a top surface with a groove formed therein, the groove configured to receive the cladding section of the fibers.

15. The single-station splicing unit of claim 14 , wherein ends of the cladding section of the fibers are configured to be positioned in an abutting relationship in the notched area of the alignment element.

16. The single-station splicing unit of claim 14 , wherein the at least one cover includes an extension complementary to the groove formed in the top surface of the alignment element, the extension configured to seat the cladding section of the fibers within the groove of the alignment element.

17. A single-station splicing system, comprising:
a fusion splicer; and
a single-station splicing unit configured to be positioned within the fusion splicer, the single-station splicing unit including:
a housing including an interior space and at least one cover configured to be interlocked with the housing to enclose the interior space;
an alignment element removably disposed within the interior space of the housing;
a first electrode disposed on one side of the housing; and
a second electrode disposed in the housing on an opposing side from the first electrode and in a facing relationship with the first electrode;
wherein the housing is configured to receive fibers in an opposing and abutting relationship to splice the fibers;
wherein the alignment element is configured to support a cladding section of the fibers, and interlocking of the at least one cover with the housing is configured to radially secure the cladding section of the fibers against the alignment element; and
wherein the housing remains secured to the fibers after splicing.

18. The single-station splicing system of claim 17 , wherein the fusion splicer includes a cradle configured to receive the single-station splicing unit.

19. The single-station splicing system of claim 17 , wherein the fusion splicer includes electrical contacts configured to electrically connect with the first and second electrodes of the single-station splicing unit.

20. A method of splicing, comprising:
positioning a first fiber and a second fiber in an opposing and facing relationship within an interior space of a housing of a single-station splicing unit, each of the first and second fibers including a cladding section and a coated section, the single-station splicing unit including an alignment element removably disposed within the interior space, and first and second electrodes disposed on opposing sides of the housing;
positioning ends of the cladding section of the first and second fibers in an abutting relationship in the interior space of the housing with the alignment element supporting the cladding section of the first and second fibers;
interlocking a cover with the housing to enclose the cladding section of the first and second fibers within the interior space of the housing, wherein interlocking the cover with the housing radially secures the cladding section of the first and second fibers against the alignment element; and
creating a voltage arc between the first and second electrodes to splice the ends of the cladding section of the first and second fibers;
wherein the housing remains secured to the first and second fibers after splicing.

21. The single-station splicing unit of claim 1 , wherein:
the housing includes a main body section defining the interior space and including first, second and third covers connected to the main body section;
each of the first, second and third covers is capable of being independently pivoted and interlocked relative to the main body section to enclose at least a portion of the interior space;
each of the fibers
