Fibre optic connector QOLTEC 54177 — Qoltec 54177

Fibre optic connector QOLTEC 54177 is a passive optical adapter intended for joining two LC/UPC terminated fibers. It provides a stable mechanical interface that aligns fiber endfaces to enable low-loss signal transmission in fiber optic networks. The Qoltec 54177 model is designed in a female–female configuration and is suitable for use in telecommunications, data centers and other network installations where precise LC/UPC connections are required.

Advantages

The adapter supports LC/UPC-to-LC/UPC mating with a female–female arrangement, ensuring consistent alignment of ferrules and repeatable connections. Being a passive component, it requires no power and contributes minimal insertion loss when properly installed. Its compact form factor allows integration into patch panels, distribution boxes or inline fiber assemblies without occupying significant space.

Suitable for

• Telecommunications backbone and access links
• Data center fiber patching and rack installations
• Fiber optic patch panels and distribution enclosures
• Laboratory and test-bench fiber coupling for LC/UPC connectors

Key specifications

• Connector type: LC/UPC to LC/UPC
• Configuration: female – female
• Function: passive optical adapter for fiber alignment
• Typical application: singlemode and multimode networks using LC/UPC terminations
• Form factor: compact inline adapter suitable for panels and boxes

How to use

Insert LC/UPC-terminated fiber cables into each side of the Qoltec 54177 adapter until they click or seat firmly, ensuring the ferrule endfaces meet the alignment sleeve inside the adapter. Verify clean endfaces before mating to minimise insertion loss and back reflections; use appropriate fiber cleaning tools and visual inspection. When removing cables, gently pull on the connector body rather than the fiber jacket to avoid strain on the termination.

Usage recommendations

To maintain optimum performance, keep LC/UPC endfaces clean and protected when not in use, store the adapter in a dust-free environment, and avoid excessive bending or mechanical stress on connected fibers. Confirm compatibility with your network's singlemode or multimode cabling and perform optical loss checks after installation.
