SKLS3 Fiber Cleaver for Repeatable FTTH Fusion-Splice Preparation
SKLS3 fiber cleaver is a mechanical preparation tool for producing a flat, repeatable end face on stripped optical fibre before fusion splicing, mechanical splicing or connector termination. Its commercial value is not the number of cuts printed on the box; it is the ability to deliver stable cleave geometry across technicians, blade positions and field conditions.
SKLS3 uses one-step press action with automatic blade return and is best suited to high-volume FTTH drop-cable and pigtail preparation where technicians want a compact universal fixture and repeatable operating sequence. LinkFiber can supply the cleaver as a stand-alone tool or as part of a project kit with the matched stripper, cleaning materials, spare blade, carrying case and work instruction.
Best Fit in a Fiber Splicing Workflow
Process step | Required control | Why it affects splice yield |
Strip | Remove jacket, strength members and coating without nicking the glass | A damaged fibre can break during cleaving, loading or service. |
Clean | Use fresh lint-free wipes and suitable high-purity alcohol; allow the fibre to dry | Coating debris or gel contaminates the blade and creates hackle or angled end faces. |
Set length | Place the prepared fibre against the correct scale/stop without axial tension | Prepared length must match the fusion-splicer holder, sleeve process or connector specification. |
Cleave | Close and operate the tool using the model-specific sequence; do not twist or pull the fibre | Side load and vibration can produce lips, chips and inconsistent angles. |
Inspect and splice | Use the splicer image/cleave-angle estimate and monitor splice-loss trend | A single acceptable image does not prove the tool remains stable over a production lot. |
Dispose of scrap | Collect all glass fragments in a closed sharps container | Bare fibre scraps are difficult to see and can penetrate skin or contaminate work areas. |
A fibre cleaver never cuts an intact 2.0 × 3.0 mm drop cable or a jacketed jumper directly. A multi-slot fixture may hold the prepared cable or coated fibre, but the cable jacket, strength members and coating must first be stripped so the blade contacts clean 125 µm glass. This distinction prevents broken blades, poor end faces and unsafe glass fragments.
Model Selection and Configuration Control
Choose SKLS3 when a standardized one-step workflow and fixed prepared-fibre length suit the splice protector, fast connector or splicer holder used by the project.
The existing specification lists a fixed 18 mm prepared-fibre length, 16 indexed blade positions and a supplier-stated total design life of at least 48,000 cleaves. These are purchase specifications to verify on the approved sample; actual blade life depends on glass cleanliness, blade height, indexed position and maintenance.
Before purchasing, confirm coating diameter, cladding diameter, prepared-fibre length, holder type, single or ribbon construction, blade code, spare-blade availability, waste-collection method and the operator sequence. Photographs alone are insufficient because similar housings may contain different holders or adjustment systems.

What the Cleaver Actually Controls
The cleaver creates a controlled fracture in the glass. It does not polish the end face and it cannot by itself guarantee splice loss. The result depends on the blade edge initiating the crack, correct bending stress, stable clamping and a fibre free from coating residue. Fusion-splicer cleave-angle estimates are useful process indicators, but they are not a substitute for inspecting a representative sample and monitoring actual splice performance.
Single-mode and multimode fibres normally share a 125 µm cladding diameter, but coating, bend sensitivity, ribbon geometry and holder requirements vary. G.652.D and G.657.A access fibres can be processed when the holder and stripped length are correct; unusual coatings, fibres above standard cladding diameter or specialty fibres require project testing.
Blade Life, Position Indexing and Adjustment
Published blade life is normally a design estimate derived from multiple indexed edge positions. It should not be treated as a guaranteed number of acceptable cleaves without maintenance. A blade position should be advanced only after cleaning, fibre preparation and loading have been ruled out. Blade height changes fracture geometry and should be adjusted with the supplied tool in small controlled steps, then validated with a cleave sample—not changed to chase one poor splice.
Common Cleaving Failures and Prevention
Observed problem | Likely cause | Corrective action |
High or variable cleave angle | Dirty blade, fibre not seated flat, worn position, excessive side load or wrong blade height | Clean the clamp and blade area, reseat the fibre, index to a qualified position and verify height with the approved procedure. |
Lip, hackle, chip or mirror-zone defect | Contaminated glass, damaged coating strip, blade damage or uncontrolled operating motion | Re-strip and clean the fibre; inspect blade edge and repeat using the model-specific sequence. |
Good cleave but high splice loss | Wrong fibre program, core/cladding mismatch, dirty electrodes, bend in holder or poor alignment | Do not adjust the cleaver blindly; isolate splicer, fibre and cleaver contributions with controlled samples. |
Fibre breaks before cleave | Glass was nicked during stripping or clamped under tension | Inspect stripper condition, avoid bending the bare fibre and reload without axial load. |
Short blade life | Cleaving dirty fibre, repeated use of one position, incorrect height adjustment or abrasive contamination | Use a maintenance log, rotate only after a verified decline and protect the cleaver in its case. |
Prepared length does not fit holder | Wrong scale/fixture or confusion between coating diameter and cable size | Approve the complete strip-and-cleave work instruction using the actual cable, holder and sleeve. |
Pre-shipment Quality and Acceptance Plan
For a B2B order, LinkFiber can qualify the exact cleaver, blade and holder combination against a written inspection plan. A practical lot check uses the buyer’s representative fibre and stripper, performs repeated cleaves across selected units, reviews the end-face image or splicer cleave-angle estimate and records defects, operating feel, scrap collection and accessory completeness.
- Approve one exact model and blade/holder construction before volume production.
- Test a representative sequence rather than reporting only one best cleave.
- Record fibre type, coating diameter, prepared length, blade position and operator.
- Set acceptance limits for angle distribution, visible defects and successful splice rate.
- Verify blade indexing, adjustment tool, waste box or scrap-control method and spare-part supply.
- Check protective packing, label, manual and ordered accessories before shipment.
B2B Buyer Guide: Information Required for an Accurate Quote
Send the fibre or cable type, cladding and coating diameter, single or ribbon count, target prepared-fibre length, fusion-splicer or fast-connector model, expected daily workload, quantity, destination, spare-blade requirement and private-label needs. For tenders, add the inspection method, sampling level, required reports and exact compliance documents.
For medium-sized contractors and distributors, total cost should include blade availability, repeatability, technician training time, fixture compatibility, scrap safety and after-sales adjustment support. A cheaper cleaver that causes repeat splices, wasted sleeves and return visits can cost more than the tool itself.
