## Summary description

QOLTEC 54140 is a fibre optic connector designed for passive optical link connections. The product provides a mechanical interface for joining optical fibers and is suitable for patching, extension, or replacement in fiber networks. Specific optical parameters (singlemode/multimode, insertion loss, connector type) are not specified and should be confirmed before installation.

## Long description

QOLTEC 54140 is a fibre optic connector designed as a passive coupling solution for optical link connections. It provides a mechanical interface for joining optical fibers and is intended for patching, extension, or replacement tasks in fibre networks. Specific optical parameters such as whether it is for singlemode or multimode fiber, exact insertion loss, or detailed connector polishing specifications are not specified and should be confirmed before installation.
Advantages
The connector offers a compact simplex design with SC/APC interfaces that simplifies physical connection between two optical terminations. As a passive adapter, it requires no power and provides a straightforward mechanical alignment for mating ferrules. Its construction supports standard patching workflows and can be used in rack, wallbox, or field environments when compatible connectors are present.
Suitable for
Temporary or permanent fibre patching between two SC/APC terminated cables
Extending existing optical runs by coupling two fibre ends
Replacing a damaged or missing passive coupling in a fiber distribution panel or enclosure
Key specifications
Connector interfaces: SC/APC
Configuration: simplex
Function: passive fibre optic coupling/adapter
Primary use: mechanical alignment and connection of optical ferrules
How to use
Ensure the connector interfaces on both fibre cables are clean and free of dust or debris before making a connection. Align the SC/APC ferrules and insert each cable into the adapter until they seat securely with the expected mechanical click or stop. Verify physical stability and, where possible, test the optical link for continuity and acceptable signal loss using appropriate test equipment. If the singlemode or multimode compatibility is uncertain, confirm fiber types and connector polish to avoid increased insertion loss or back reflection.
Usage recommendations
Use fibre cleaning tools (wipes, cleaning pens) before every connection, avoid excessive bending at the cable entry, and confirm connector compatibility (SC/APC) and fibre type prior to permanent installation. For links carrying critical signals, perform optical loss and return loss measurements after installation.
