Abstract

The present invention relates to a low-profile splice protection system for protecting multi-fibre fusion splice sites. The splice protection system comprises coating material to package the splice site and may comprise a protective housing.

Claims (21)

1. A multi-fiber optical connector comprising:

a plurality of stubs spliced to a row of cable fibers at a splice location;

a flexible splice protector having only a first sidewall component and a separate second sidewall component, the first and second sidewall components extending in parallel along opposing sides of the row of the cable fibers in the direction of a length of the cable fibers and defining a length of the flexible splice protector, the first and second sidewall components extending across the splice location, the first and second sidewall components connected at a first longitudinal side and at a second longitudinal side along the length of the flexible splice protector, the flexible splice protector having a width between the first and second longitudinal sides and a thickness between the first and second sidewall components, the width being at least six times as large as the thickness; and

a connector body housing the flexible splice protector and having a multi-fiber ferrule connected to the plurality of stubs on a first end and a cable of the row of cable fibers extending from a second end,

wherein the first and second sidewall components are connected by snap components, wherein the flexible splice protector includes at least one port for injecting adhesive.

2. The multi-fiber optical connector of claim 1 , wherein the multi-fiber optical connector further comprises a spring surrounding a portion of the length of the splice protector.

3. The multi-fiber optical connector of claim 1 , wherein the flexible splice protector further comprises splice protection material between the first and second sidewall components surrounding gaps within the row of cable fibers at the splice location.

4. The multi-fiber optical connector of claim 1 , wherein the flexible splice protector is made from polymeric material.

5. The multi-fiber optical connector of claim 1 , wherein the first and second sidewall components are rectangular in shape.

6. The multi-fiber optical connector of claim 1 , wherein the length of the flexible splice protector is greater than the width.

7. The multi-fiber optical connector of claim 1 , wherein the flexible splice protector may be bent without causing damage.

8. The multi-fiber optical connector of claim 1 , wherein the flexible splice protector does not include a reinforcement member.

9. The multi-fiber optical connector of claim 1 , wherein the flexible splice protector does not require heating.

10. The multi-fiber optical connector of claim 1 , wherein the snap components are defined in secondary wall extensions of the first and second sidewall components, wherein the secondary wall extensions run adjacent to the first and second longitudinal sides.

11. The multi-fiber optical connector of claim 1 , wherein the first and second sidewall components are substantially structurally identical.

12. The multi-fiber optical connector of claim 1 , wherein the first and second sidewall components are first and second half-shells.

13. A multi-fiber optical connector comprising:

a plurality of stubs spliced to a row of cable fibers at a splice location;

a flexible splice protector having a first sidewall and a separate second sidewall extending in parallel along opposing sides of the row of the cable fibers in the direction of a length of the cable fibers and defining a length of the flexible splice protector, the first and second sidewalls extending across the splice location, the first and second sidewalls connected at a first end and at a second end along the length of the flexible splice protector, the flexible splice protector having a width between the first and second ends and a thickness between the first and second sidewalls, the width being at least six times as large as the thickness; and

a connector body housing the flexible splice protector and having a multi-fiber ferrule connected to the plurality of stubs on a first end and a cable of the row of cable fibers extending from a second end;

wherein the multi-fiber optical connector further comprises a spring surrounding a portion of the length of the splice protector.
