Abstract

A fiber optic cable which is preterminated in the factory. A first fiber optic cable on a reel enters a splicing (or splitting) receptacle. Some optical fibers continue through the receptacle and exit the receptacle into a second fiber optic cable, while other optical fibers in the first fiber optic cable are spliced in the receptacle to a third set of optical fibers which exit the receptacle into a third fiber optic cable such as a stub cable. A cable repair sleeve is installed over the receptacle assembly to seal and protect the completed receptacle area. The cables and receptacle are then coiled on a reel for shipment to the customer site.

Claims

1. A preterminated optical cable, comprising:

(a) a receptacle having opposing first and second openings;

(b) a first tube entering the receptacle first opening and secured to the receptacle;

(c) a second tube and a third tube, the second and third tubes entering the receptacle second opening and secured to the receptacle;

(d) a first set of optical fibers which (i) are carried by the first and second tubes, and (ii) proceed through the receptacle between the first and second tubes;

(e) a second set of optical fibers carried by the first tube and a third set of optical fibers carried by the third tube, the second and third set of optical fibers in optical communication with each other in the receptacle; and

(f) a reel on which the receptacle, first tube, second tube, and third tube are placed for shipment.

2. A preterminated optical cable as described in claim 1, wherein the number of optical fibers in the second and third sets are equal.

3. A preterminated optical cable as described in claim 1, further comprising a splicing tray mounted in the receptacle in which the second and third sets of optical fibers are spliced.

4. A preterminated optical cable as described in claim 3, further comprising a moisture proof container around the receptacle and a portion of the first, second, and third tubes adjacent to the receptacle.

5. A preterminated optical cable as described in claim 1, wherein the number of optical fibers in the first tube is greater than the number of optical fibers in the second tube.

6. A preterminated optical cable as described in claim 5 wherein the number of optical fibers in the first tube is greater than the number of optical fibers in the third tube.

7. A preterminated optical cable as described in claim 4, further comprising an optical splitter in the receptacle.
