Sumitomo FC-6S High Precision Fiber Optic Cleaver
The Sumitomo FC-6S is a traditional benchtop fiber cleaver engineered for technicians who prioritize cleave consistency and long blade life in a simple, reliable form factor. With a typical cleave angle of 0.5° and a blade rated for up to 54,000 cleaves across 24 rotation positions, the FC-6S is a workhorse tool for splice preparation in central offices, MDF/IDF cabinets, and controlled field environments.
Its pre-fitted single fiber adapter and optional off-cut collector make it easy to set up and keep your workspace clean. The field-replaceable blade means minimal downtime — swap it on-site without sending the tool in for service.

Frequently Asked Questions
Q: What is the difference between the FC-6S and FC-6RS?
A: The FC-6S is the standard single-fiber benchtop cleaver. The FC-6RS is a ribbon-capable variant. If you need to cleave ribbon fiber, please contact us to confirm the correct model for your application.
Q: Is the off-cut collector included?
A: The off-cut collector is optional and may not be included in the standard package. Please check the product listing or contact us to confirm what is included with your order.
Q: How do I rotate the blade to a new position?
A: The FC-6S blade has 24 rotation positions. Refer to the instruction manual for the blade rotation procedure. No special tools are required for standard blade rotation.
Q: Is the FC-6S compatible with Sumitomo fusion splicers?
A: Yes. The FC-6S produces cleave lengths (5–20 mm) compatible with Sumitomo's T-400S, Z-2C, and Type-82 series splicers, as well as most third-party fusion splicers.
Q: Can the FC-6S cleave drop cable or 3 mm jacket fiber?
A: The FC-6S is designed for bare fiber (125 µm cladding). For drop cable or jacketed fiber cleaving, a fiber stripper must be used first to expose the bare fiber before cleaving.
Note: Cleave angle is measured at room temperature with a new blade. Actual performance may vary with blade condition, fiber type, and operating technique.
