Fujikura CB-07 Replacement Blade for CT-08 Fiber Optic Cleaver – 48,000-Cleave Life, Genuine AFL OEM Part
The Fujikura CB-07 is the genuine replacement blade for the Fujikura CT-08 (CT08) precision fiber optic cleaver. With a rated service life of 48,000 fiber cleaves, the CB-07 is the correct blade to restore your CT-08 cleaver’s cutting performance when the blade becomes dull — delivering the clean, low-angle end-faces required for low-loss fusion splices and fast connector terminations.
A worn cleaver blade is one of the most common — and most overlooked — causes of poor splice quality in the field. High cleave angles, lip defects, hackle marks, and fiber end-face chips all increase splice loss and connector insertion loss. Replacing the CB-07 blade at the recommended interval restores the CT-08’s cleave quality to factory specification.

About the Fujikura CT-08 Cleaver
The Fujikura CT-08 is a high-precision fiber optic cleaver widely used in FTTH construction, telecom OSP splicing, and field termination. It is the standard cleaver bundled with many Fujikura fusion splicer kits, including the Fujikura 41S kit. The CT-08 uses a rotating blade system that presents a fresh cutting edge at each blade position — the CB-07 blade is the OEM replacement when all positions have been used and cleave quality begins to degrade.
Why Cleaver Blade Replacement Matters for Splice Quality
- Increasing cleave angle: A dull blade produces higher cleave angles. IEC standards require cleave angles below 0.5° for singlemode fusion splicing — a worn blade frequently exceeds this threshold, causing high splice loss
- Lip and hackle defects: Dull blades produce lip defects and hackle marks, both of which increase splice loss and connector insertion loss
- Fiber end-face chips: A worn blade may chip the fiber end-face rather than producing a clean fracture, causing splice failures and wasted fiber
- Increased fiber breakage: A dull blade requires more scoring force, increasing the risk of fiber breakage during the cleave cycle
Signs Your Fujikura CT-08 Cleaver Needs a New Blade
- The cleaver’s blade position indicator has reached the end of its rotation range
- Cleave angles are increasing — consistently above 0.5°
- Splice loss is increasing on fiber types that previously spliced well
- Lip or hackle defects are visible on fiber end-faces
- Fiber breakage during cleaving is occurring more frequently than expected
CB-07 vs. CB-08: Which Fujikura Cleaver Blade Do You Need?
| Part Number | Compatible Cleaver | Blade Life |
|---|---|---|
| CB-07 (this listing) | Fujikura CT-08 / CT08 | 48,000 cleaves |
| CB-08 | Fujikura CT-50 / CT50 | 48,000 cleaves |
Always verify your cleaver model before ordering. The CT-08 and CT-50 are different cleaver models requiring different blades — the CB-07 and CB-08 are not interchangeable even though they share the same blade life rating.
Frequently Asked Questions
Q: What is the Fujikura CB-07?
A: The Fujikura CB-07 is the genuine OEM replacement blade for the Fujikura CT-08 (CT08) precision fiber optic cleaver. It is rated for 48,000 fiber cleaves.
Q: Which cleaver is the CB-07 compatible with?
A: The CB-07 is compatible with the Fujikura CT-08 / CT08 fiber optic cleaver. It is not compatible with the Fujikura CT-50, which uses the CB-08 blade.
Q: How many cleaves does the CB-07 blade last?
A: The CB-07 blade is rated for 48,000 fiber cleaves.
Q: What is the difference between the CB-07 and CB-08?
A: The CB-07 is for the Fujikura CT-08 cleaver. The CB-08 is for the Fujikura CT-50 cleaver. They are not interchangeable — always verify your cleaver model before ordering.
Q: Is the CB-07 a genuine Fujikura / AFL part?
A: Yes. The CB-07 is a genuine Fujikura / AFL OEM replacement blade.
Q: Is the CT-08 the standard cleaver in the Fujikura 41S splicer kit?
A: Yes. The CT-08 is the standard cleaver bundled with the Fujikura 41S splicer kit. The CB-07 is the correct replacement blade for this configuration.
