5.0  Fiber Repositioning for 

3M

™

 Fibrlok

™

 II Angle Fiber  

Splice 2529-AS

5.1 

If high loss is observed after a splice has been 
actuated, it is possible that the fiber ends are 
separated. In this case, lift the splice cap and 
reposition fiber ends, as instructed below.

Note:  If the splice has been in service, place the splice 

back into the tool. Insert the fiber holders into the 
tool and push them towards the splice. Recreate 
fiber bows on both sides of the splice and close 
the fiber clamps to maintain the angled cleaved 
fiber keying.

Note:  Do not completely remove fiber from Fibrlok 

splices.

5.2 

Place the two fiber holders into Fibrlok assembly tool 
base and open the guide funnel, middle covers and 
the back clamp on the fiber holder.

5.3 

Insert Fibrlok into the tool and lay the fibers in 
the appropriate channels so there is no twist in the 
fibers. Ensure the fiber holders are fully inserted into 
the tool.

5.4 

Lightly close the fiber clamp on the holder so the 
fiber can move under the clamp.

5.5 

Create a fiber bow and then fully clamp the fiber. 
Repeat with the second fiber. Ensure second bow is 
the same size as first bow.

5.6 

While the splice is in the splice holding cradle, insert 
the short prongs of the 3M

™

 Fibrlok

™

 II Splice cap 

lifter into the two holes on the side of the splice. 
The cap lifter will be at an angle to the splice. The 
long prongs will be resting against the top of the 
splice cap.

5.7 

Slide the bottom of the cap lifter inward until it is in 
a vertical position, lifting the splice slightly out of the 
cradle.
