Optical fiber repair apparatus with adjustable guide member and methods for using the same
View Patent ↗Optical fiber repair apparatus include a longitudinally extending closure frame having a longitudinally extending optical fiber receiving groove in a face thereof. An adjustable guide member on the closure frame is longitudinally movable thereon to adjust a position of an optical fiber of a first optical fiber cable in the groove. A first attachment member is configured to couple the first optical fiber cable to the guide member with the optical fiber of the first optical fiber cable extending into the optical fiber receiving groove. A retainer is configured to couple a second optical fiber cable to the closure frame with an optical fiber of the second optical fiber cable extending into the optical fiber receiving groove.

a retainer configured to couple a second optical fiber cable to the closure frame with an optical fiber of the second optical fiber cable extending into the optical fiber receiving groove.
2. The apparatus of claim 1 wherein the adjustable guide member is configured to direct the optical fiber of the first optical fiber cable into the groove.
3. The apparatus of claim 1 wherein the retainer is configured to direct the optical fiber of the second optical fiber cable into the groove.
4. The apparatus of claim 3 wherein the retainer comprises a second adjustable guide member configured to direct the optical fiber of the second optical fiber cable into the groove and a second attachment member configured to couple the second optical fiber cable to the second adjustable guide member.
5. The apparatus of claim 2 wherein the optical fiber of the first optical fiber cable is positioned in an optical fiber tube and wherein the adjustable guide member is configured to direct the optical fiber tube into the groove.
6. An optical fiber repair apparatus, comprising:
a longitudinally extending closure frame having a longitudinally extending optical fiber receiving groove in a face thereof;
an adjustable guide member on the closure frame and longitudinally movable thereon to adjust a position of an optical fiber of a first optical fiber cable in the groove;
a first attachment member configured to couple the first optical fiber cable to the guide member with an optical fiber of the first optical fiber cable extending into the optical fiber receiving groove, wherein the optical fiber of the first optical fiber cable is positioned in an optical fiber tube; and
a retainer configured to couple a second optical fiber cable to the closure frame with an optical fiber of the second optical fiber cable extending into the optical fiber receiving groove;
wherein the adjustable guide member comprises a slide member having an opening therein configured to slidably engage an outer surface of the closure frame, the optical fiber tube being received into the opening and directed to the groove by contact with the slide member in the opening and wherein the opening includes a rotary limit portion configured to contact a rotary limit portion of the closure frame to limit rotational movement of the guide member about the closure frame.
7. The apparatus of claim 5 wherein the first optical fiber cable further includes a strength member and wherein the attachment member is configured to connect the strength member to the guide member.
8. An optical fiber repair apparatus, comprising:
a longitudinally extending closure frame having a longitudinally extending optical fiber receiving groove in a face thereof;
an adjustable guide member on the closure frame and longitudinally movable thereon to adjust a position of an optical fiber of a first optical fiber cable in the groove, wherein the guide member has an opening therein and wherein the optical fiber of the first optical fiber cable is positioned in an optical fiber tube and wherein the first optical fiber cable further includes a strength member;
a first attachment member configured to couple the first optical fiber cable to the guide member with the optical fiber of the first optical fiber cable extending into the optical fiber receiving groove; and
a retainer configured to couple a second optical fiber cable to the closure frame with an optical fiber of the second optical fiber cable extending into the optical fiber receiving groove;
wherein the guide member includes a strength member receiving opening therein configured to receive the strength member for attachment therein and wherein the strength member receiving opening is positioned to provide an angular displacement between the strength member and the optical fiber tube extending from the first optical fiber cable to force the optical fiber tube against the guide member in the opening in the guide member and direct the optical fiber tube into the groove.
9. The apparatus of claim 8 wherein the first optical fiber includes two strength members extending therein on opposite sides of the optical fiber tube and wherein the guide member includes two strength member receiving openings therein positioned above the closure frame and the opening in the guide member and on opposite sides of the groove.
10. The apparatus of claim 8 wherein the closure frame further comprises a longitudinally extending guide channel configured to receive a flat drop cable.
11. The apparatus of claim 8 wherein the closure frame includes longitudinally extending contact surfaces configured to receive a round drop cable.
12. The apparatus of claim 11 wherein the contact surfaces include edges of the groove.
13. The apparatus of claim 1 , further comprising a splice cover configured to be positioned on the closure frame over the groove.
14. The apparatus of claim 13 further comprising an outer closure positioned around and enclosing the closure frame to provide environmental sealing for a cable splice therein and strain relief for the first and second optical fiber cables extending therein.
15. The apparatus of claim 14 wherein the outer closure comprises a heatshrink or cold seal outer closure.
16. The apparatus of claim 1 , further comprising a cable fixture configured to receive and retain the closure frame at a position proximate a splice device.
17. The apparatus of claim 16 wherein the cable fixture comprises:
a cable frame configured to receive the closure frame;
a first retention member configured to retain the first optical fiber cable; and
a second retention member configured to retain the second optical fiber cable.
