Splicing Fiber and Pigtail
The fiber cable must have SC/APC connectors. If it does not, you can splice a pigtail,
which has SC/APC connectors, to the fiber cable.
There are two different pigtails: 1 for single-mode fiber (PN 4013SCAPC-3) and 1
for multimode fiber (PN 4012SCAPC-3).
To splice the fiber optic cable to the SC/APC pigtail: Option A
1. Secure both the fiber cable and the SC/APC pigtail in a splice tray that is installed
immediately adjacent to the Hub.
2. Prepare the fiber end by ring-cutting the polyethylene jacket, cutting back the
Kevlar strands, and stripping back the fiber cladding.
Ensure that sufficient slack is maintained in order to be able to reach the fusion
splicer.
3. Clean the unclad fiber core using isopropyl alcohol and lint-free wipes.
4. Cleave the unclad fiber to the length prescribed by the fusion splicer’s specifica-
tion sheets.
5. Repeat steps 2 through 4 for the SC/APC pigtail.
6. Pass the splice sleeve onto the fiber strand.
7. Position both fiber ends in the fusion splicer and complete splice in accordance
with the fusion splicer’s operation instructions.
8. Ensure that the estimated loss for the splice as measured by the fusion splicer is
0.10 dB or better.
9. Slide the fusion splicing sleeve over the point of the fusion splice.
10. Place the sleeve and fused fiber into the fusion splicer’s heater.
11. Allow time for the splice sleeve to cure.
12. Return fiber splice to the splice tray, store the sleeve in a splice holder within the
tray, and store excess cable length in accordance with the tray manufacture’s
directions.
After successfully testing the fiber, plug the SC/APC pigtail into the proper opti-
cal port on the Hub.
