Sumitomo FC-6S+ High Precision Fiber Optic Cleaver
Frequently Asked Questions
What is the blade life of the Sumitomo FC-6S+?
The FC-6S+ blade delivers up to 54,000 cleaves across 24 blade positions (2,250 cleaves per position). The blade is field-replaceable, so you can extend tool life without returning it for service.
What is the difference between the Sumitomo FC-6 and FC-6S+?
The FC-6S+ is the upgraded model featuring an off-cut collector option and improved blade positioning system compared to the original FC-6. Both models share the same ≤0.5° cleave angle specification and 125μm cladding compatibility, but the FC-6S+ offers enhanced field serviceability.
Is the Sumitomo FC-6S+ compatible with fusion splicers?
Yes. The FC-6S+ produces cleave lengths of 5–20mm, which is compatible with most Sumitomo fusion splicers (including the T-57, T-82, and Z-2C series) as well as other major brands. Always verify the required cleave length for your specific splicer model.
What fiber types does the FC-6S+ support?
The FC-6S+ supports single silica glass fiber with a 125μm cladding diameter — the standard for SMF-28, G.652D, G.657A1/A2, and most FTTH single-mode fibers. It is not designed for ribbon fiber or multi-fiber cleaving.
Does the FC-6S+ come with a warranty?
Yes, every Sumitomo FC-6S+ purchased from opticfibertool.com includes a 12-month warranty.
