Fibre optic InfiniBand cable LANBERG FO-SUSU-MD31-0050-TQ, single-mode duplex, 0.5 m

LANBERG FO-SUSU-MD31-0050-TQ is a fibre optic InfiniBand duplex patch cable designed for high-speed optical links. The cable uses multimode 50/125 µm optical fibres with OM3 performance, SC connectors with UPC polish and a duplex construction. It has a 5 m length, 3.0 mm diameter, LSZH coating and an aqua jacket color, making it suitable for structured cabling in data centres, server racks and network equipment interconnects where reliable short-reach optical connectivity is required.

Advantages

This LANBERG duplex multimode cable provides low insertion loss and high return loss suitable for InfiniBand and other high-bandwidth applications. The SC/UPC connectors ensure consistent end-face geometry for stable optical performance. The LSZH coating reduces smoke and toxic gas emission in case of fire, and the 3.0 mm cable diameter with a 7.5 mm minimum bend radius supports neat routing in cable trays and tight spaces. The cable operates across a wide temperature range and is coloured aqua for easy identification in multimode installations.

Suitable for

• Short-range optical links between InfiniBand switches, HBAs and storage nodes
• Patch connections in data centre racks and fibre panels
• High-bandwidth applications requiring OM3 multimode performance
• Environments where low-smoke zero-halogen cabling is required

How to use

Inspect connector end-faces for contamination before insertion and clean with appropriate fibre cleaning tools if necessary. Align the SC connectors with the corresponding ports on transceivers, switches or patch panels and insert until a positive latch is felt. Route the cable following rack and tray pathways while respecting the minimum bend radius to avoid increased attenuation or mechanical damage. For removal, depress the SC latch and withdraw the connector in a straight motion to prevent stress on the fibre.

Usage recommendations

Use this OM3 multimode duplex cable for short-reach InfiniBand connections and ensure cleaning and handling procedures are followed. Avoid tight bends, excessive tensile load and exposure to harsh chemicals. Store spare cables coiled loosely and protected from dust to maintain connector performance.
