Abstract

Optical fiber mass splice methods and assemblies are provided. A method may include securing a fiber clamp to a fiber setting fixture, the fiber setting fixture including a fiber alignment block and a backstop. A plurality of fiber grooves may be defined in the fiber alignment block. The method may further include inserting a plurality of optical fibers into the fiber setting fixture such that each of the plurality of optical fibers is disposed in one of the plurality of fiber grooves and contacts the backstop. The method may further include loading, after the inserting step, each of the plurality of optical fibers into the fiber clamp. The method may further include clamping the plurality of optical fibers in the fiber clamp.

First claim

What is claimed is:

1. A optical fiber mass splice method, comprising:
securing a fiber clamp to a fiber setting fixture, the fiber setting fixture comprising a fiber alignment block and a backstop, wherein a plurality of fiber grooves are defined in the fiber alignment block;
inserting a plurality of optical fibers into the fiber setting fixture such that each of the plurality of optical fibers is disposed in one of the plurality of fiber grooves and contacts the backstop;
loading, after the inserting step, each of the plurality of optical fibers into the fiber clamp;
clamping the plurality of optical fibers in the fiber clamp; and
transporting the loaded and clamped fiber clamp from the fiber setting fixture to a splicer.

2. The method of claim 1 , wherein the fiber clamp comprises at least one groove, and further comprising aligning the at least one groove of the fiber clamp with the plurality of fiber grooves of the alignment block.

3. The method of claim 2 , wherein the fiber clamp is secured to a fiber clamp mount, and wherein the fiber clamp mount is movable relative to the fiber alignment block along at least one axis.

4. The method of claim 1 , wherein the plurality of fiber grooves of the fiber setting fixture each extend along a lengthwise direction, and wherein the plurality of optical fibers are inserted along the lengthwise direction until each of the plurality of optical fibers contacts the backstop.

5. The method of claim 1 , wherein the fiber setting fixture further comprises a cover, the cover disposed on the fiber alignment block and at least partially enclosing the plurality of fiber grooves during the inserting step, and further comprising removing, after the clamping step, the cover from the plurality of fiber grooves.

6. The method of claim 5 , wherein the cover is a magnet.

7. The method of claim 1 , wherein a longitudinal axis, lateral axis, and transverse axis are defined by the fiber setting fixture, and wherein the plurality of fiber grooves extend at an angle to a plane defined by the longitudinal axis and lateral axis.

8. The method of claim 1 , wherein the fiber clamp comprises a clamp body and a connector holder, the connector holder comprising an arm extending from the clamp body and a plurality of connector clips mounted to the arm.

9. The method of claim 8 , wherein the plurality of connector clips are removably mounted to the arm.

10. The method of claim 8 , wherein the arm is cantilevered from the clamp body and the plurality of connector clips are mounted at a free end of the arm.

11. The method of claim 1 , wherein the plurality of optical fibers are loose optical fibers.

12. The method of claim 1 , wherein the plurality of optical fibers form a ribbon.

13. An optical fiber mass splice assembly, comprising:
a fiber setting fixture, the fiber setting fixture comprising:
a fiber alignment block, wherein a plurality of fiber grooves are defined in the fiber alignment block;
a backstop;
a fiber clamp mount movable relative to the fiber alignment block along at least one axis; and
a cover removably enclosing at least a portion of the plurality of fiber grooves;

a fiber clamp, the fiber clamp removably securable to the fiber clamp mount, the fiber clamp comprising:
a clamp body and at least one groove defined in the clamp body; and
a connector holder, the connector holder comprising an arm extending from the clamp body and a plurality of connector clips mounted to the arm.

14. The optical fiber mass splice assembly of claim 13 , wherein the cover is a magnet.

15. The optical fiber mass splice assembly of claim 13 , wherein a longitudinal axis, lateral axis, and transverse axis are defined by the fiber setting fixture, and wherein the plurality of fiber grooves extend at an angle to a plane defined by the longitudinal axis and lateral axis.

16. The optical fiber mass splice assembly of claim 13 , wherein the plurality of connector clips are removably mounted to the arm.

17. The optical fiber mass splice assembly of claim 13 , wherein the arm is cantilevered from the clamp body and the plurality of connector clips are mounted at a free end of the arm.
