Cleave the fiber
4
Before cleaving the fiber, make sure the fiber is clean and
properly prepared (See steps 1-3)
.
Cleave the fibers using a high quality cleaving tool that offers
a flat end-face at an angle of less than 1
o from the perpen-
dicular (less than 0.5
o
for small core fiber). To ensure good
splicing, you must also observe the instructions for cleaving
lengths detailed below.
Cleaving lengths (plus V-groove selection)
Use Blue V-grooves
(Clamping on bare fiber)
Use Black V-grooves
(Clamping on primary coating)
Loose secondary coating
> 12 mm
primary coating
> 5 mm
> 5 mm
Primary coating
Tight secondary coating
Primary coating
> 17 mm
> 17 mm

Fiber preparation checklist
Fiber preparation is often
the decisive phase in
successful splicing, so it is
important to ensure that
you can check off on the
