Fiber cleavers: choosing the right model
Cleave quality caps your splice quality — the best six-motor splicer cannot fix a 2° cleave angle. This lesson maps cleaver classes to jobs so you buy capability, not features.
- 1
Field FTTx work → C-10 / C-20 class
16-fiber capability, a few thousand cuts per blade. Light, economical, ideal for drop cable and patch cords.
- 2
Backbone / high-count trays → C-30 class
Higher precision (≤0.5° typical), single-fiber focus, thousands of cuts with a position-rotating blade. The standard partner for TC-600-class splicers.
- 3
Ribbon work → ribbon cleaver
Mass-cleaves 8–16 fiber ribbons flat; pair with TC-600M. Never mass-cleave with a single-fiber cleaver.
- 4
Large-core / specialty fiber → C-90
For 105–400 μm cladding fibers used with LDF-6000D-400; standard cleavers crush large fibers.
- 5
Blade economics
A blade has 12 positions × thousands of cuts. Rotate position per the counter, not "when it feels dull" — log rotations on the tool body.
Field tips from TEKCN engineers
- Cleaver angle failure shows up in the splicer as rejected cleaves — check blade position first, before recalibrating anything else.
- Keep the fiber clamps clean; a grain of gel on the clamp pads tilts the fiber and skews every cleave.
