 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.
