Fibre optic cable LANBERG FO-SASA-SS31-0200-WH 20 m G.657.B3 SC–SC White

LANBERG FO-SASA-SS31-0200-WH is a 20 m single-mode fibre optic cable with G.657.B3 fibre and SC–SC APC connectors. Built as a simplex 9/125 µm cable with LSZH coating and 3.0 mm diameter, it is suitable for optical networking links, data center interconnects, server rack patching and telecom installations where low bend loss and compatibility with standard SC ports are required.

Advantages

The cable uses G.657.B3 single-mode fibre that offers low bend sensitivity and reliable transmission performance in confined routing environments. SC APC connectors provide stable optical contact and reduced back reflection, while the LSZH outer coating reduces smoke and toxic emissions in case of fire. With a small 3.0 mm cable diameter and a minimum bend radius of 5 mm, the cable is compact and flexible for tight routing paths.

Suitable for

• Data center interconnects and patch panels
• Server rack to equipment optical links
• Telecom and access network installations
• Environments requiring tight bend routing and space-saving cabling

How to use

Route the cable between SC-compatible optical ports, ensuring SC APC connectors are clean and free of dust before mating. Avoid excessive tensile loads during installation and maintain the minimum bend radius of 5 mm to preserve optical performance. Secure the cable with appropriate clips or cable management in racks and enclosures to prevent sharp bends or crushing. After installation, perform insertion loss and return loss measurements to verify link performance.

Recommendations

For optimal performance, clean SC APC connector endfaces with approved fibre cleaning tools before connection, avoid repeated tight bends near terminations, and use appropriate strain relief when routing through cabinets and conduits. The LSZH jacket makes this cable suitable for indoor installations where reduced smoke emission is required.
