Fibre optic connector QOLTEC 54178 — QOLTEC 54178

Fibre optic connector QOLTEC 54178 is a ready-made component designed for joining or terminating single-mode optical fibres in communication networks. This compact LC/UPC to LC/UPC female–female connector is intended for installations that require reliable, low-loss optical connections, routine maintenance, repairs, or integration into patch panels and field splices. The product is suitable for adjusting optical power levels in equipment chains and for preserving signal quality across fibre links.

Advantages

The connector provides a standardized LC/UPC interface on both ends in a compact female–female format, enabling straightforward mating with LC/UPC plugs and adapters. Its factory-polished UPC ferrules reduce back-reflection and maintain consistent insertion loss. The ready-made construction saves assembly time compared with field-terminated solutions and offers repeatable performance in distribution frames, patch panels, and pre-terminated assemblies.

Suitable for

• Telecommunication and data centre fibre patching
• Repair and replacement of damaged connectorized fibre links
• Integration into patch panels, adapters, and small footprint splice enclosures
• Maintenance tasks requiring compact LC/UPC female-to-female coupling

Key specifications

• Connector type: LC/UPC to LC/UPC
• Polish type: UPC (ultra physical contact)
• Gender: female — female
• Applicable fibre: single-mode optical fibre
• Form factor: compact duplex LC-style
• Typical use: inline coupling, patching and termination

How to use

Install the connector by mating it with corresponding LC/UPC male plugs or adapters until a secure click is felt. Use the component within existing patch panels or adapter modules designed for LC duplex fittings, or place it inline between two LC-terminated pigtails for temporary or permanent coupling. Ensure fibre ends and mating adapters are clean before connection to prevent increased insertion loss or contamination. Follow standard fibre handling practice: avoid excessive bending, secure cable strain relief, and keep dust caps in place when the connector is not in use.

Usage recommendations

For optimal performance, clean both mating ferrules with appropriate fibre cleaning tools before assembly, verify insertion loss and return loss with suitable test equipment after installation, and store spare connectors in a clean, dry environment. Use this LC/UPC female–female connector in single-mode links where low back-reflection and compact coupling are required.
