Fibre optic cable LANBERG FO-SASU-SS21-0030-YE — 3 m, G.657.A1, SC–SC, yellow

LANBERG FO-SASU-SS21-0030-YE is a 3 m single-mode (9/125 µm) simplex fibre optic patch cable designed for short interconnections in racks, patch panels and equipment links. The cable uses ITU-T G.657.A1 bend-insensitive fibre and LSZH sheath in a yellow 3.0 mm jacket. Both ends are terminated with SC connectors, available in APC or UPC polishing options, offering low insertion loss and high return loss for reliable optical links in telecommunications and data centre environments.

Advantages

The G.657.A1 fibre reduces sensitivity to tight bends and routing limitations, allowing installation in confined spaces or densely cabled racks. The LSZH jacket minimizes smoke and toxic emissions in case of fire, meeting safety requirements for indoor deployments. SC–SC terminations provide a common, easy-to-connect interface and the specified insertion loss of < 0.25 dB with return loss > 60 dB ensures low signal degradation for short patching and equipment-to-equipment connections.

Suitable for

• Patch panel to switch or transceiver short links
• Rack-to-rack and intra-rack optical connections
• InfiniBand or fibre channel short optical runs requiring SC terminations
• Environments where bend-insensitive fibre routing is needed (tight bends, cable ducts)

How to use

Use the LANBERG SC–SC single-mode patch cable to connect SC ports on patch panels, transceivers or network devices. Route the cable along cable management channels and avoid sharp bends beyond the specified 10 mm minimum bend radius to maintain optical performance. Ensure connectors are clean and dust-free before insertion; when required, use appropriate dust caps during storage. Select APC or UPC polishing based on equipment compatibility and return loss requirements.

Usage recommendations

For best performance, inspect and clean SC connector endfaces with approved fibre cleaning tools before each installation. Prefer gentle routing inside racks and trays to preserve the bend-insensitive properties of G.657.A1 fibre, and avoid repeated tight bending at the same point. Use LSZH cables for indoor installations where fire safety standards require low-smoke, halogen-free materials.
