## Long description

The EFB Elektronik 53316.3 fibre optic adapter provides a single-mode SC connection in blue designed for reliable mating of optical fibres. Supplied as a single adapter, it enables alignment of SC connectors to maintain low insertion loss and consistent signal performance in single-mode networks. Its format and colour coding match standard SC single-mode installations, making it suitable for patch panels, couplers and equipment interfaces where compact, stable connections are required.
Advantages
The SC single-mode adapter is manufactured to deliver low insertion loss and high return loss stability across standard single-mode fibres. Its blue housing provides visual identification for single-mode links and simplifies cabling management. The adapter's precision alignment sleeve ensures repeatable connections and reduces the need for frequent re-terminations. Sold individually, it allows targeted replacement or expansion without excess inventory.
Suitable for
 Single-mode fibre patch panels and distribution frames
 Connecting SC-terminated patch cords and pigtails
 Telecom and datacom backbone links
 Laboratory test setups and field repairs
Key specifications
 Connector type: SC (single-mode)
 Fibre type: single-mode
 Housing colour: blue (single-mode coding)
 Format: simplex adapter (single coupling)
 Material features: precision alignment sleeve for stable mating
How to use
Insert SC-terminated fibre connectors into each side of the adapter until a positive mechanical click or stop is felt to ensure proper mating. Use clean connectors and inspect endfaces prior to connection to minimize insertion loss and prevent contamination. When replacing an existing adapter, power down active equipment if required by your safety procedures, remove the old adapter and install the new adapter in the panel or housing, then reconnect the SC patch cords. Test the link with appropriate optical test equipment after installation to verify attenuation and continuity.
Usage recommendations
Maintain clean connector endfaces using suitable fibre cleaning tools before each connection, avoid excessive bending of fibre near the adapter, and store unused adapters or dust caps to protect mating surfaces. For best long-term performance, follow standard fibre handling and installation practices and verify connections with an optical power meter or OTDR when integrating into live networks.
