Fibre optic connector QOLTEC 54101 – single connector for fiber optic cabling

QOLTEC 54101 is a singleconnector fibre optic pigtail designed to join or terminate singlemode fiber optic cabling. Built to the G.652D standard and equipped with an LC/APC connector, this 3 m pigtail with a 0.9 mm cable diameter provides a compact mechanical junction for optical networks, enabling low-loss signal transmission between fiber strands or to active equipment in installations, repairs and extensions.

Advantages

The LC/APC connector offers angled physical contact to reduce back reflection, improving signal integrity in singlemode links. Compliance with the G.652D standard ensures compatibility with common singlemode fibers and predictable attenuation characteristics. The 0.9 mm buffered cable diameter and 3 m length give a balance of flexibility and reach for terminating fibers in racks, patch panels or field splice points while maintaining a lightweight, compact profile.

Suitable for

• Termination of singlemode fiber in data centre patch panels and optical distribution frames
• Repairing or replacing damaged fiber ends in field installations
• Connecting fiber pigtails to transceivers, adapters and optical equipment using LC/APC interfaces
• Extending optical runs where a preterminated single connector is required

Key specifications

• Fiber type: singlemode (G.652D)
• Connector type: LC/APC (angled physical contact)
• Cable diameter: 0.9 mm buffered fiber
• Cable length: 3 m
• Application: pigtail for termination and splicing

How to use

Strip the outer jacket and prepare the fiber according to standard fiber preparation procedures, cleave to the required length, and secure the buffered pigtail in a splice tray or termination point. Use an appropriate fusion splicer or mechanical splice to join the pigtail to the installed fiber, or insert the LC/APC connector into a compatible adapter or transceiver for direct termination. Handle the LC/APC connector by the body and keep endfaces clean and protected with caps until insertion to avoid contamination and increased insertion loss.

Usage recommendations

Inspect and clean connector endfaces before installation, use dust caps when idle, and perform loss and reflectance testing after splicing or termination to verify optical continuity and insertion loss meet system requirements.
