Fiber optic connector CBO SFA21BK3 LC single‑piece, blue

CBO SFA21BK3 LC single-piece connector in blue is a compact fibre optic termination component designed for LC interfaces. It provides a single-piece, duplex-compatible form factor that simplifies termination of single fibre cables and supports reliable connections in telecom and data networking environments. The connector is intended for use with patch panels, fibre pigtails and field terminations where a small footprint and consistent LC performance are required.

Advantages

The single-piece construction reduces assembly complexity and improves mechanical stability compared with multi-part designs. Its LC form factor preserves a small footprint and compatibility with standard LC adapters and receptacles. The blue colour provides clear visual identification for multimode or designated network lines, while the connector design ensures consistent optical alignment and repeatable mating performance.

Suitable for

• Field terminations of single fibre cables
• Creating fibre pigtails for splicing
• Installing connections in patch panels and distribution frames
• Telecom and enterprise data network cabling

Key specifications

• Connector type: LC single-piece
• Colour: blue for easy identification
• Form factor: compact, duplex-compatible single-piece design
• Application: single fibre termination and mating
• Compatibility: fits standard LC adapters and receptacles

How to use

Prepare the fibre by stripping and cleaning according to standard fibre handling procedures. Insert the prepared fibre into the connector body following the manufacturer's assembly sequence and secure the fibre as required by the connector design. Verify end-face cleanliness and inspect the ferrule before mating to avoid contamination. After installation, test the connection for insertion loss and return loss using appropriate test equipment to confirm acceptable optical performance.

Usage recommendations

Use appropriate fibre cleaning tools and inspection microscopes to ensure end-face quality. When deploying in installed systems, label and document connector locations and maintain strain relief to prevent fibre movement. For critical links, perform acceptance testing after installation and follow industry best practices for handling and storage of fibre connectors.
