7.5 Splicing Fiber Optic Cable
The fiber cable must have SC/APC connectors for the entire run. If it does not, you
can splice a pigtail, which has SC/APC connectors, to the fiber cable.
LGC offers two pigtails: one for single-mode fiber (PN 4013SCAPC-3) and one for
multi-mode fiber (PN 4012SCAPC-3).
LGC Wireless recommends fusion splices because they have the lowest splice loss
and return loss. Mechanical splices have higher losses and higher back reflection than
fusion splices and are not recommended.
Using a fusion splicer involves fusing together two butted and cleaved ends of fiber.
The fusion splicer aligns the fibers and maintains alignment during the fusion pro-
cess. fusion splices have very low loss (typically less than 0.05 dB) and very low
back reflection (return loss). Fusion splices should be organized in a splice tray
designed to store and protect the splices.
Fusion Splicing of Fiber and Pigtail
Before you begin, make sure the fusion splicer is set to the proper mode (that is,
single- or multi-mode).
To fusion 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 cutting back the polyethylene jacket, the kevlar or fiber-
glass strength members, the extruded coating, and the buffer coating in order to
expose the “bare fiber” – cladding plus core.
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.
