## Long description

Fibre optic connector QOLTEC 54143 is a single connector designed to terminate and join singlemode fiber lines. Supplied by Qoltec, this compact SC/APC duplex adapter provides a stable mating interface for fiber optic cables used in telecommunications, broadband networks and signal distribution systems. Its format allows quick installation and reliable optical contact where low back reflection and consistent alignment are required.
Advantages
This SC/APC duplex fibre optic connector offers low insertion loss and low return loss suitable for singlemode links. The compact duplex design simplifies routing and space management in patch panels and distribution boxes. The connector is compatible with standard SC/APC ferrule geometry which ensures repeatable mating and dependable physical protection for fiber endfaces.
Suitable for
 Singlemode fiber patching in indoor telecommunication racks and cabinets
 FTTx distribution and customer premises equipment
 Optical signal distribution and testing setups
 Replacement or upgrade of existing SC/APC duplex connections
Key specifications
 Connector type: SC/APC duplex
 Fiber type: singlemode
 Application: fiber termination and interconnection
 Form factor: compact duplex adapter for two fibers
 Performance focus: low insertion loss and low back reflection for singlemode networks
How to use
Prepare the singlemode fiber according to standard termination practice, ensuring a clean, precisely cleaved endface. Align the SC/APC ferrule with the mating adapter and insert until it clicks or seats fully, observing the duplex orientation for correct channel mapping. For best optical performance, inspect and clean connector endfaces before mating and avoid excessive bending near the connector body. When removing, pull the connector straight out to prevent stress on the fiber.
Usage recommendations
Use appropriate fiber cleaning tools and inspection scopes to maintain endface quality. Install the connector in compatible SC/APC ports and follow standard singlemode handling procedures: avoid sharp bends, secure cables to relieve strain, and store unused ports with protective caps.
