## Summary description

The Qoltec 54431 fibre optic connector LC/APC is designed for single-mode applications. It comes in green, silver, and yellow colors.

## Long description

The Qoltec fibre optic connector LC/APC 54431 is a single-mode connector designed for high-density installations and professional fibre networks. Supplied in green, silver and yellow versions and packaged in sets of 200 pieces, this connector set supports low attenuation and reliable mating for single-mode optical lines. The compact pack dimensions (20 mm width, 100 mm depth) make storage and handling straightforward on site or in a warehouse. The connector uses a ceramic ferrule with an 8° angled polished face (APC) to reduce back reflections and improve signal quality in applications where low reflectance is important.
Advantages
The LC form factor provides a small footprint suited to high-density patch panels and modules, while the latch locking mechanism secures the connection against accidental disconnection. The APC polishing angle reduces reflected light at the fibre interface, lowering return loss compared with flat-polished interfaces. A uniform ceramic ferrule ensures precise fibre alignment and consistent optical performance across all connectors in the pack.
Suitable for
 Single-mode LAN, WAN and FTTx installations
 High-density patch panels and telecommunication racks
 Cable TV distribution and railway communication systems
 Measurement and testing setups requiring low reflectance
 Bulk deployments where multiple identical connectors are needed
Key specifications
 Connector type: LC with APC angled polish
 Mode: Single-mode
 Pack quantity: 200 pieces
 Available colours: green, silver, yellow
 Ferrule material: ceramic (sintered)
 Polish angle: 8° (APC)
 Package dimensions: 20 mm (width) × 100 mm (depth)
How to use
Prepare and cleave the single-mode optical fibre according to standard fibre preparation procedures, ensuring clean and correctly stripped fibre. Insert the fibre into the connector until it seats against the ferrule, following the connector assembly instructions specific to the LC/APC type. After termination, inspect the end-face and perform an insertion loss and return loss test to confirm acceptable optical performance. Install the assembled connector into compatible LC/APC adapters or patch panels, making sure the keyed features align to maintain the angled polish orientation.
Usage recommendations
Store connectors in their original packaging until use to avoid contamination. Handle end-faces with lint-free wipes and approved cleaning fluid before mating. Use dust caps when connectors are not in service and perform routine cleaning and inspection to maintain low attenuation and low reflectance in single-mode networks.
