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.
TE offers two pigtails:
• one
for single-mode fiber (PN 4013SCAPC-3)
• one for multi-mode fiber (PN 4
012SCAPC-3).
TE recommends Fusion Wideband splices be
cause they have the lowest splice loss and return
loss. Mechanical splices have higher losses and higher back reflection than Fusion Wideband
splices and are not recommended.
Using a Fusion Wideband splicer involves fusing together two butt
ed and cleaved ends of fiber.
The Fusion Wideband splicer aligns the fibers and maintains alignment during the Fusion
Wideband process. Fusion Wideband splices have very low loss (typically less than 0.05 dB) and
very low back reflection (return loss).
Organize Fusion Wideband splices in a splice tr
ay designed to store and protect the splices.
NOTE: The following procedures assume that the system is new from the factory and that it has not
been programmed with bands. If you are replacing components in a pre-installed system with
either new units or units that may already be programmed (for example, re-using units from
another system), refer to “Replacing Fusion Wideband Components” on page 175.
Complete one of the following procedures as appropriate to the system design:
• “Option A: Fusion Wideband Splice the Fiber-Optic Cable to the SC/APC Pigta
il” on page 146
• “Option B: Fusion Wideband Splice the F
iber-Optic Cable to the SC/APC Pigtail” on page 147.
Option A: Fusion Wideband Splice the Fiber-Optic Cable to the SC/APC Pigtail
1 Make sure the Fusion Wideband splicer is set to the proper mode (that is, single- or
multi-mode).
2 Secure both the fiber cable and the SC/APC pigtail in a splice tray
that is installed immediately
adjacent to the Hub.
3 Prepare
the
fiber end by cutting back the polyethylene jacket, the kevlar or fiberglass strength
members, the extruded coating, and the buffer coating in order to expose the “bare fiber”
(cladding plus core).
4 Ensure that suffic
ient slack is maintained that can reach the Fusion Wideband splicer.
5 Clean the unclad fiber core using isopropyl alcohol and l
int-free wipes.
6 Cleave the unclad fiber to the length prescribed by the Fusion Wideband splic
er’s
specification sheets.
7 Repeat Step 4 through Step 6 for the SC/APC pigtail.
8 Pass the splice sleeve onto the fiber strand.
9 Position both fiber ends in the Fusion Wideband splicer and complete the splice in accordance
with the Fusion Wideband splicer’s operation instructions.
