1. What Is a One-Step Fiber Cleaver?
A one-step fiber cleaver (also called an automatic fiber cleaver) completes the entire cleaving process — fiber clamping, scoring, and breaking — in a single press action. Unlike traditional two-step or manual cleavers that require separate scoring and snapping motions, a one-step cleaver eliminates operator variability and delivers consistent, repeatable cleave angles critical for low-loss fusion splicing.
For FTTH deployment teams, aerial splice crews, and data center fiber technicians working in confined spaces, one-step cleavers have become the professional standard. The COMWAY CC-03 is the leading value option in this category.
2. COMWAY CC-03 Overview
COMWAY CC-03 — compact one-step automatic fiber cleaver, 85×75×45mm, 135g
The COMWAY CC-03 is a palm-sized, one-step automatic fiber cleaver engineered for professional fiber optic technicians. Manufactured by COMWAY, the CC-03 targets the growing demand for lightweight, high-precision cleavers in FTTH, telecom backbone, and data center environments.

3. Key Features & Technical Specifications
Automatic blade rotation ensures a fresh cutting edge on every cleave
One-Step Operation
The CC-03 completes clamping, scoring, and breaking in a single downward press. No secondary snap action, no manual blade positioning. This dramatically reduces operator error — especially critical during high-volume FTTH rollouts where technician fatigue is a real factor.
Automatic Blade Rotation
After each cleave, the CC-03 automatically indexes the blade to a fresh cutting position. The result: consistent ≤0.5° cleave angles across the full 50,000-cleave blade life — not just when the blade is new.
50,000-Cleave Blade Life
At a typical FTTH deployment rate of 50 cleaves/day, a single blade lasts over 2.7 years before replacement. The COMWAY CC-03 Replacement Blade ($49.99) is a direct drop-in.
Built-in Extra-Large Fiber Scrap Collector
The CC-03’s integrated scrap collector captures every cleaved fiber fragment, keeping your work area safe and compliant with fiber safety protocols.
Ultra-Compact Form Factor
At 85×75×45mm and just 135g, the CC-03 fits in a shirt pocket and operates comfortably inside fiber distribution boxes, splice closures, and aerial splice platforms.

4. Hands-On Performance: Field Test Results
CC-03 in field use — ideal for confined splice closure environments
Cleave Angle Consistency
In controlled testing across 200 consecutive cleaves on 0.9mm coated fiber, the CC-03 maintained a mean cleave angle of 0.3° with zero outliers exceeding 0.5°. This meets IEC 61300-3-35 specification and matches the performance of the Sumitomo FC-8R.

5. Who Should Buy the CC-03?
✅ Ideal for:
- FTTH deployment contractors running high-volume drop cable splicing
- Telecom field technicians working in splice closures and aerial platforms
- Data center fiber teams requiring precision in confined rack environments
- Budget-conscious professionals who need Sumitomo-class performance without the Sumitomo price
⚠️ Consider alternatives if:
- You require ribbon fiber cleaving (the CC-03 is single-core only)
- Your workflow demands cleave angle measurement display (consider the FITEL S327A)
6. CC-03 vs. Sumitomo FC-8R vs. FITEL S326
| Feature | COMWAY CC-03 | Sumitomo FC-8R | FITEL S326 |
|---|---|---|---|
| Operation | One-step auto | One-step auto | One-step auto |
| Blade Life | 50,000 | 48,000 | 48,000 |
| Cleave Angle | ≤0.5° | ≤0.5° | ≤0.5° |
| Weight | 135g | 195g | 180g |
| Price | $149.99 | ~$380–$450 | ~$320–$380 |
| Blade Cost | $49.99 | ~$120 | ~$100 |
The CC-03 matches the core cleaving performance of both premium competitors at 60–65% lower cost.
