## Summary description

Fibre optic connector QOLTEC 54134 by QOLTEC is a passive component designed to join or terminate optical fibers. It provides mechanical alignment for fiber ends and supports fibre optic cabling installations and repairs.

## Long description

Fibre optic connector QOLTEC 54134 is a passive duplex adapter designed for connection to singlemode fiber using LC/UPC connectors. It provides precise mechanical alignment for two optical fibers, enabling reliable joining, termination or extension of singlemode links in patch panels, wall outlets or field splices. The adapter accepts LC/UPC duplex plugs and maintains low insertion loss for typical network cabling and repair tasks.
Advantages
This duplex adapter supports LC/UPC terminations for singlemode fiber and is suitable for compact installations where space and alignment precision matter. The design ensures stable coupling between two LC/UPC plugs and helps minimise signal loss and back reflection when used with compatible singlemode components. Its passive construction requires no power and offers a straightforward way to extend or replace fibre connections.
Suitable for
 Connecting two singlemode LC/UPC patch cables
 Extending singlemode fibre links in patch panels or cabinets
 Field repairs and temporary fibre join applications
 Fiber management in data centres and telecom distribution points
Key specifications
 Connector type: LC/UPC duplex
 Fiber type: Singlemode
 Configuration: Duplex coupling for two fibers
 Function: Mechanical alignment and fibre joining/termination
 Insertion loss: Low (typical for precision LC/UPC adapters)
 Interface: Female-to-female adapter for LC/UPC plugs
How to use
Insert compatible LC/UPC plugs from the two fiber cables into the duplex adapter until they click into place, ensuring clean connector endfaces before mating to reduce loss and contamination. Align the adapter in the desired mounting location such as a panel or module opening and secure it if required by the installation. To disconnect, depress the connector latch and withdraw the plug carefully to avoid damaging the ferrule or fibre.
Usage recommendations
Inspect and clean connector endfaces with appropriate fiber cleaning tools before each mating, avoid excessive force when inserting or removing plugs, and use dust caps when the adapter is not in use to protect internal alignment sleeves. Match LC/UPC type and singlemode fiber specifications across all components to ensure optimal performance.
