Optical fiber connector for multi-fiber cable
Optical connector arrangements terminate at least seventy-two optical fibers. The optical connector arrangements include multiple optical ferrules that each terminates multiple optical fibers. Some example optical connectors can terminate about 144 optical fibers. Each optical connector includes a fiber take-up arrangement and a flange extending outwardly from a connector housing arrangement. The fiber take-up arrangement manages excess length of the optical fibers. A threadable coupling nut can be disposed on the connector housing arrangement to engage the outwardly extending flange. Certain types of optical connector arrangements include furcation cables spacing the connector housing arrangement form the fiber take-up arrangement.
1. A cable assembly comprising:
a fiber take-up arrangement extending between a first end of the fiber take-up arrangement and a second end of the fiber take-up arrangement, the fiber take-up arrangement defining an excess fiber storage region;
a cable including an outer jacket surrounding an optical fiber, the cable being anchored to the fiber take-up arrangement, wherein excess length of the optical fiber is disposed at the excess fiber storage region of the fiber take-up arrangement, the optical fiber having a section that extends beyond the second end of the fiber take-up arrangement;
a plug connector terminating an end of the optical fiber of the cable; and
a furcation cable extending between a first end of the furcation cable and a second end of the furcation cable, the first end of the furcation cable being anchored to the fiber take-up arrangement, the second end of the furcation cable being anchored to the plug connector, the section of the optical fiber extending through the furcation cable to the plug connector, the plug connector being external of and spaced from the fiber take-up arrangement by the furcation cable, the furcation cable being more flexible than the cable.
2. The cable assembly of claim 1 , wherein the fiber take-up arrangement includes a sealing arrangement that provides an environmental seal between the cable and the furcation cable.
3. The cable assembly of claim 1 , wherein the fiber take-up arrangement includes a mandrel disposed at the excess fiber storage region.
4. The cable assembly of claim 1 , wherein the furcation cable is a round cable.
5. The cable assembly of claim 1 , wherein the furcation cable is a flat cable.
6. The cable assembly of claim 1 , wherein the optical fiber is one of a plurality of optical fibers of the cable, wherein the plug connector terminates the plurality of optical fibers.
7. The cable assembly of claim 6 , wherein the plug connector includes a multi-fiber ferrule that terminates at least some of the optical fibers.
8. The cable assembly of claim 7 , wherein the plug connector includes a plurality of multi-fiber ferrules that terminate the optical fibers.
9. The cable assembly of claim 8 , wherein the multi-fiber ferrules are disposed in multiple rows.
10. The cable assembly of claim 1 , wherein the furcation cable includes strength members, and wherein the furcation cable is anchored to the fiber take-up arrangement and to the plug connector by the strength members.
11. The cable assembly of claim 10 , wherein the strength members of the furcation cable include first anchor boots that are shaped to match cavities defined in the fiber take-up arrangement.
12. The cable assembly of claim 11 , wherein the strength members of the furcation cable also include second anchor boots that are shaped to match cavities defined in the plug connector, the second anchor boots being disposed at an opposite side of the furcation cable from the first anchor boots.
13. The cable assembly of claim 1 , wherein the cable includes at least seventy-two optical fibers.
14. The cable assembly of claim 13 , wherein the cable includes at least ninety-six optical fibers.
15. The cable assembly of claim 14 , wherein the cable includes at least 144 optical fibers.
16. The cable assembly of claim 1 , further comprising a twist-to-lock fastener that rotatably mounts about the plug connector.
17. The cable assembly of claim 16 , wherein the twist-to-lock fastener includes threads.
18. The cable assembly of claim 1 , further comprising a seal carried by the plug connector that provides environmental sealing between the plug connector and a component at which the plug connector is received.
19. The cable assembly of claim 1 , wherein the outer jacket of the cable extends into the first end of the fiber take-up arrangement and a jacket of the furcation cable extends into the second end of the fiber take-up arrangement.
20. The cable assembly of claim 1 , wherein the fiber take-up arrangement aligns the cable with the furcation cable.
