Fujikura CB-08 Replacement Blade for CT-50 Fiber Optic Cleaver – 48,000 Cleaves, Genuine AFL

Fujikura CB-08 Replacement Blade for CT-50 Fiber Optic Cleaver – 48,000-Cleave Life, Genuine AFL Part

The Fujikura CB-08 is the genuine replacement blade for the Fujikura CT-50 (CT50) precision fiber optic cleaver. With a rated service life of 48,000 fiber cleaves, the CB-08 is the correct blade to restore your CT-50 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 causes of poor cleave 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-08 blade at the recommended interval restores the CT-50’s cleave quality to factory specification.

Key Specifications

Compatible Cleaver Models

If you are unsure whether the CB-08 is compatible with your specific cleaver model, please contact us before ordering. For the Fujikura CT-08 cleaver, the correct blade is the CB-07.

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-50 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-08 vs. CB-07: Which Fujikura Cleaver Blade Do You Need?

Always verify your cleaver model before ordering. The CT-50 and CT-08 are different cleaver models requiring different blades — the CB-08 and CB-07 are not interchangeable.

Frequently Asked Questions

Q: What is the Fujikura CB-08?
A: The Fujikura CB-08 is the genuine replacement blade for the Fujikura CT-50 (CT50) precision fiber optic cleaver. It is rated for 48,000 fiber cleaves.

Q: Which cleaver is the CB-08 compatible with?
A: The CB-08 is compatible with the Fujikura CT-50 / CT50 fiber optic cleaver. It is not compatible with the Fujikura CT-08, which uses the CB-07 blade.

Q: How many cleaves does the CB-08 blade last?
A: The CB-08 blade is rated for 48,000 fiber cleaves.

Q: How do I know when to replace the CB-08 blade?
A: Replace the blade when the CT-50’s blade position indicator has reached the end of its rotation range, when cleave angles consistently exceed 0.5°, when lip or hackle defects appear on fiber end-faces, or when fiber breakage during cleaving increases.

Q: What is the difference between the CB-08 and CB-07?
A: The CB-08 is for the Fujikura CT-50 cleaver. The CB-07 is for the Fujikura CT-08 cleaver. They are not interchangeable — always verify your cleaver model before ordering.

Q: Is the CB-08 a genuine Fujikura / AFL part?
A: Yes. The CB-08 is a genuine Fujikura / AFL OEM replacement blade.
