Abstract

Methods for splicing optical fibers include coupling a first optical fiber cable to a longitudinally extending closure frame and coupling a second optical fiber cable to an adjustable guide member on the closure frame. The adjustable guide member is moved toward the first optical fiber cable to provide a distance between the first and second optical fiber cable less than an exposed length of the first and second optical fiber therebetween to provide a slack length of optical fiber. Cleaved exposed ends of a first optical fiber from the first optical fiber cable and a second optical fiber from the second optical fiber cable are positioned proximate each other in a splice station displaced from the closure frame utilizing the slack length of optical fiber. The first and second optical fibers are spliced in the splice station and the adjustable guide member is moved away the first optical fiber cable to remove the slack length and position the spliced optical fibers in the closure frame.

Claims (22)

1. A method for splicing optical fibers, the method comprising:

coupling a first optical fiber cable to a longitudinally extending closure frame;

coupling a second optical fiber cable to an adjustable guide member on the closure frame;

moving the adjustable guide member toward the first optical fiber cable to provide a distance between the first and second optical fiber cable less than an exposed length of the first and second optical fiber therebetween to provide a slack length of optical fiber;

positioning cleaved exposed ends of a first optical fiber from the first optical fiber cable and a second optical fiber from the second optical fiber cable proximate each other in a splice station displaced from the closure frame utilizing the slack length of optical fiber;

splicing the first and second optical fibers in the splice station; and

moving the adjustable guide member away the first optical fiber cable to remove the slack length and position the spliced optical fibers in the closure frame.

2. The method of claim 1 wherein positioning exposed cleaved ends is preceded by:

exposing a length of the first optical fiber;

exposing a length of the second optical fiber; and

cleaving respective exposed ends of the first and second optical fiber.

3. The method of claim 2 wherein moving the adjustable guide member is followed by:

securing the adjustable guide member to the closure frame in a position where the spliced optical fibers therein have the slack length removed; and

environmentally sealing the closure frame with the spliced optical fibers therein.

4. The method of claim 3 wherein environmentally sealing is preceded by placing a cover on the closure frame with the spliced optical fibers therein and wherein environmentally sealing comprises securing a heatshrink and/or cold seal outer closure around the closure frame.

5. The method of claim 1 wherein moving the adjustable guide member is preceded by:

coupling a cable fixture to a splice apparatus including the splice station; and

coupling the closure frame to the cable fixture.

6. The method of claim 1 wherein the method comprises repairing a broken fiber drop cable where the break defines a first exposed end and a second exposed end of a broken optical fiber therein and wherein the first exposed end comprises an exposed end of the first optical fiber cable and wherein the second optical fiber cable comprises a bridging optical fiber cable with an opposite cleaved end of the second optical fiber extending from the bridging optical fiber and wherein the opposite cleaved end of the second optical fiber is spliced to the second exposed end of the broken optical fiber cable using a second closure frame.

7. The method of claim 1 wherein the first optical fiber comprises a first plurality of optical fibers and the second optical fiber comprises a second plurality of optical fibers and wherein splicing the first and second optical fibers comprises splicing respective ones of the first and second plurality of optical fibers.

8. The method of claim 1 wherein splicing the first and second optical fibers is followed by positioning a protective sleeve over the splice and wherein moving the adjustable guide member includes positioning the protective sleeve in the closure frame.

9. The method of claim 1 wherein the second optical fiber cable includes a strength member and wherein coupling the second optical fiber cable to an adjustable guide member comprises connecting the strength member to the adjustable guide member.
