What Is the FC-6S Fiber Cleaver?

การ FC-6S Fiber Cleaver is a precision tool used to create clean, smooth, and consistent end faces on optical fibers before fusion splicing. It’s primarily designed for single fiber cleaving (typically 250µm or 900µm fibers), and delivers a cleave angle of less than 0.5°, which is essential for low splice loss.
This compact, portable, and easy-to-use cleaver has become a staple tool in FTTH, LAN, data center, and telecom network deployment.
คุณสมบัติหลัก
High Precision Cleaving
The FC-6S delivers accurate cleaving with minimal angle deviation (<0.5°), which ensures optimal splice quality and low insertion loss.
16-Position Rotatable Blade
The tungsten steel blade is durable and designed for long-term use, offering up to 48,000 cleaves (16 positions × 3 height levels).
Single Fiber Cleaving
It supports standard 125µm cladding optical fibers with 250µm or 900µm coating diameters.
Automatic Fiber Collector (Optional)
Some FC-6S models come with a built-in fiber scrap collector to safely capture fiber shards after cleaving.
Compact and Lightweight
With dimensions of approximately 63mm x 76mm x 63mm and a weight of only 380g, it’s ideal for field and in-house operations.

FC-6S vs Other Fiber Cleavers
There are many fiber cleavers in the market — from basic hand cleavers to premium automatic models like Fujikura CT-50. So where does the FC-6S stand?
Affordability
The FC-6S is highly cost-effective. Compared to high-end models that cost $1,000+, this cleaver is often available at under $100 while delivering acceptable cleaving performance.
ความทนทาน
The tungsten steel blade and sturdy base make it rugged enough for regular use in harsh field conditions.
Compatibility
Works with most fusion splicers, making it a versatile addition to any fiber splicing toolkit.
Manual Operation
Unlike auto-cleavers, the FC-6S requires manual handling, which can introduce variability in inexperienced hands.
Not Ideal for Ribbon Fiber
This cleaver is optimized for single fiber. For ribbon fiber cleaving (6, 12, or more fibers), specialized ribbon cleavers are recommended.
How to Use the FC-6S Fiber Cleaver (Step-by-Step)

- Prepare the Fiber
Strip the protective coating (250µm or 900µm) and clean the fiber with alcohol wipes. - Open the Clamp Arm
Lift the clamp lever to prepare for fiber insertion. - Insert the Fiber
Place the fiber in the V-groove with the correct length using the built-in ruler for accuracy. - Close the Clamp Arm
This secures the fiber in place. - Cleave the Fiber
Gently press down the cleaving blade. The blade will score and snap the fiber cleanly. - Remove Cleaved Fiber
Carefully lift the clamp and retrieve the cleaved fiber. If equipped, the fiber collector will store scrap ends. - Inspect
Use a fiber microscope to verify the cleave quality before fusion splicing.
Maintenance Tips for FC-6S Fiber Cleaver
To ensure long life and reliable performance:
- Rotate the Blade after every 3,000 cleaves. Use all 16 positions evenly.
- Clean the Blade and V-Groove regularly with alcohol swabs.
- Keep the Cleaver Covered when not in use to protect from dust.
- Replace the Blade after 48,000 cleaves or when cleave quality deteriorates.
Who Should Use the FC-6S Fiber Cleaver?
This tool is ideal for:
- FTTH Installers
- Field Technicians
- In-House Fiber Network Maintenance
- ISPs and Contractors on Budget
- Vocational Training Labs
It’s especially useful for professionals who need a balance of cost and functionality without compromising too much on cleave quality.
