Fibre optic connector QOLTEC 54138 — Qoltec 54138

Fibre optic connector QOLTEC 54138 is an SC/UPC simplex adapter designed to join or terminate multimode fiber optic lines. The connector provides a standardized mechanical interface for SC/UPC fiber cables, enabling reliable optical continuity in telecom, data networks and FTTH installations. Its simplex form factor is suitable for single-channel connections where a compact, single-fiber link is required.

Advantages

The SC/UPC termination offers stable alignment and low insertion loss for multimode fibers, while the simplex housing ensures a compact footprint and easy handling during installations. The adapter is compatible with standard SC connectors and supports repeated mating cycles without significant degradation of performance. Its construction is focused on maintaining signal integrity and facilitating straightforward repairs or extensions of fiber links.

Suitable for

• Connecting multimode fiber optic segments in local area networks (LAN)
• FTTH drops and subscriber termination points
• Repairs and extensions of existing fiber links
• Telecom and data centre patching where single-fiber connections are needed

Key specifications

• Connector type: SC/UPC
• Fiber mode: Multimode
• Configuration: Simplex (single fiber)
• Function: Adapter / termination for optical cable joints
• Compatibility: Standard SC fiber connectors

How to use

Ensure both fiber ends are clean and free of dust or debris before insertion. Align the SC/UPC connectors and push them into the adapter until a secure mechanical click is felt. Verify optical continuity with appropriate testing equipment or by checking signal levels on connected devices. For repairs, carefully strip and prepare the fiber according to standard procedures before terminating or mating with the adapter.

Usage recommendations

Use appropriate fiber cleaning tools and visual inspection methods before each connection to minimize insertion loss and back reflection. Store unused connectors in protective caps and avoid excessive bending of fibers near the connector to preserve performance.
