InfiniBand/fibre optic cable BlueOptics 10424-BL 5 m QSFP28 Male/Male

The BlueOptics 10424-BL is a 5 m InfiniBand/fibre optic direct attach solution with QSFP28 male connectors on both ends. Designed for high-speed data transmission, this cable supports 100G applications and provides a compact, single-cable link for short‑range connections inside racks or between adjacent racks. The cable meets MSA-defined QSFP28 breakout and electrical specifications for use with hardware platforms that accept QSFP28 to QSFP28 connections and is suitable for Ethernet, FCoE and InfiniBand workloads when used within the supported reach.

Advantages

The BlueOptics 10424-BL offers a straightforward, low-latency connection with a standard QSFP28 interface and a 5 m length that fits common data‑center topologies. As a passive direct attach option for short distances, it consumes minimal power and has a simple design that reduces failure points. The cable is manufactured to industry MSA guidelines and uses components selected to provide stable performance in high-throughput environments.

Suitable for

• High-performance computing clusters and InfiniBand fabrics
• 100G switches and routers with QSFP28 ports
• Top-of-rack and adjacent-rack interconnects in data centers
• Storage systems and servers requiring short-range 100G links

Key specifications

• Cable type: InfiniBand / fibre optic direct attach (QSFP28 to QSFP28, male/male)
• Length: 5 meters
• Connector standard: QSFP28
• Supported data rates: up to 100 Gbit/s (per cable, depending on equipment)
• Design: passive direct attach suitable for short-distance electrical/optical links

How to use

Insert each QSFP28 male connector firmly into the corresponding QSFP28 ports on the devices to be linked, ensuring the connectors are aligned and latched according to the host hardware instructions. Confirm that connected devices are configured to accept passive direct attach cables and that their firmware or software settings support the intended 100G protocol (Ethernet, FCoE or InfiniBand). After connection, verify link establishment and performance through device management interfaces or monitoring tools.

Recommendations

Use the cable for short-range interconnects inside racks or between adjacent racks; avoid routing the cable through areas with sharp bends, excessive tension or exposure to liquids. Check compatibility lists of your switch, server or storage vendor to confirm full support for passive QSFP28 direct attach connections before installation.
