Fibre optic connector FC/APC Qoltec 54443 Single-mode Green Silver Yellow

The Qoltec 54443 fibre optic connector FC/APC is designed for single-mode applications and supplied in a pack of 200 pieces. Built with a threaded FC-style body and an 8° angled polished ceramic ferrule, this connector provides repeatable, low-loss connections for fiber optic lines. Available in green, silver and yellow finishes, the connector suits installations where stable, low-reflection joints are required. The pack weight is approximately 1.07 kg, making it convenient for bulk deployment in telecommunications or data network projects.

Advantages

The threaded FC body ensures a mechanically secure and vibration-resistant joint that maintains optical performance during handling. The APC (angled physical contact) ferrule face reduces back-reflection and improves return loss compared with flat polish types. Ceramic ferrule construction gives precise fiber alignment and consistent attenuation characteristics. Supplied in a high-count pack, these connectors support efficient mass termination or replacement without frequent reordering.

Suitable for

• Single-mode fiber optic links in telecommunications
• Data center backbone and long-distance point-to-point connections
• FTTx installations requiring low back-reflection
• Laboratory and field testing where multiple connectors are used

• Ferrule polish: 8° angled polish to minimize back-reflection
• Body finish: Available in green, silver and yellow
• Pack quantity: 200 pieces
• Approximate pack weight: 1.07 kg

How to use

Prepare the fiber end according to standard single-mode termination procedures and ensure the ferrule and mating adapter are clean and free of dust. Insert the fiber into the connector body and secure it following the connector-specific termination method (crimp, adhesive, or pre-assembled procedure as applicable). When mating connectors, screw the FC threaded coupling until fully tightened to achieve a stable optical joint. Verify insertion loss and return loss with appropriate test equipment after termination and before placing the link into service.

Recommendations

Use cleaning tools and lint-free wipes with isopropyl alcohol or manufacturer-recommended cleaning fluid to maintain low attenuation and prevent contamination. Avoid excessive mechanical stress on terminated fibers and store unused connectors in their protective caps or packaging until installation. For links sensitive to back-reflection, always choose APC-polished connectors and verify return loss to confirm performance.
