BlueOptics QK734A-BO InfiniBand fibre optic cable 5 m LC OM4

The BlueOptics QK734A-BO InfiniBand fibre optic cable 5 m LC OM4 is a multimode optical link designed for high-speed data transmission in professional network environments. With LC connectors and OM4 grade fibre it provides low attenuation and stable signal integrity for full duplex InfiniBand connections over a 5 metre span. The cable’s 50 µm core diameter is compatible with standard multimode transceivers and is suitable for short to medium reach links within racks and between adjacent equipment in data centers and server rooms.

Advantages

This OM4 multimode cable supports higher bandwidth and improved modal dispersion performance compared with lower-grade multimode fibres, helping maintain signal quality for InfiniBand links. The LC connectors ensure a compact, reliable connection suitable for high-density patch panels and transceiver modules. Its 5 m length offers flexibility for neat cable routing within racks while keeping latency and insertion loss to a minimum.

Suitable for

• InfiniBand host and switch interconnects in data centers
• Short-run multimode connections between servers, storage and network devices
• High-density patch panels and transceiver ports using LC connectors
• Applications requiring full duplex multimode fibre runs with 50 µm core

Key specifications

• Fibre type: OM4 multimode fibre
• Connector type: LC duplex
• Length: 5 metres
• Core diameter: 50 µm
• Mode: full duplex
• Typical use: short to medium reach data center cabling

How to use

Connect one LC connector to the InfiniBand transceiver or port on the host or switch and the matching LC connector to the corresponding port on the remote device, ensuring correct orientation for transmit and receive pairs. Route the cable to avoid sharp bends and mechanical stress; maintain the manufacturer’s minimum bend radius to prevent signal degradation. For rack installations, use cable management accessories to secure the run and label both ends for easy identification during maintenance.

Recommendations

For optimal performance, use OM4-compatible transceivers and keep connections clean by inspecting and, if necessary, cleaning LC end faces before mating. Avoid tight bends and direct mechanical strain; in high-density installations, plan routing to minimize connector strain and crosstalk. Regularly verify link status and perform optical loss testing if troubleshooting signal issues.
