1) 3M Fibrlok II Splice Holder 2539
2) Buffer Stripper
3) Scissors (Snips)
3.0 Tools and Materials required
4.0 Splicing Set-Up
The splicing area should be clean, dry and well lit. A
clean, well organized splicing area will improve splice
efficiency and minimize the risk of contamination of
fibers or splices.
4) Reagent Grade Isopropyl Alcohol
5) Lint-free Wipes
6) Cleaver
4.2 Open buffer tubes, expose and clean the fibers per your
company practice.
Remove the Fibrlok II Splice/Holder from its
protective package.

4.5
Before proceeding, attach the splice/holder to its final location. If there is not enough space to work, then
attach the splice/holder after completing the splice. Clean surface of dirt and debris with alcohol and a
lint-free cloth. To attach, remove the 3M VHB ™ (Very High Bond) Tape release liner (red) and press
the splice/holder base firmly for several seconds onto the surface of its final location.
Lift the buffer clamps at both ends of the
splice/holder and lift the actuation lever to the “up”
position
Note: The 3M Fibrlok II Splice/Holder is designed for 900
μ
m tight buffer and 250
μ
m primary coated
fiber. To splice 900
μ
m loose tube, semi-tight, or release layered fiber remove the 900
μ
m coating within the
last four inches or more from the fiber end to be cleaved.
Note: VHB Tape is not re-positionable.
5.0 Fiber Preparation
4.1
Remove the minimum length of the cable outer jacket
needed to prepare and splice fibers.
5.1
Strip 1.5 to 1.75 inches (38mm to 45mm) of plastic coating
from the fiber using a clean mechanical stripper.
5.2
Clean the bare glass by pulling the fiber through an alcohol
soaked lint-free wipe.
5.3
Note: Do not wipe the fibers more than two times, and limit the time that the bare fiber is exposed to the
atmosphere.
Cleave the fiber to 12.5mm +/- 0.5mm (0.49+/0.02 inches) for both 250
μ
m and 900
μ
m tight buffer
coated fibers.
5.3
Note: Do not clean fibers again after they have been cleaved or allow cleaved ends to contact tools.
