InfiniBand/fibre optic cable HPE X240 100G QSFP28 1m

The HPE X240 100G QSFP28 1m cable is a one-metre high-speed connectivity solution for data centers and high-performance computing environments. With QSFP28 connectors on both ends and support for 100 Gigabit links, it is designed for short-reach, low-latency connections between switches, network adapters and other QSFP28-capable devices. The cable is intended to provide reliable transmission for InfiniBand and fibre optic network architectures where consistent throughput and signal integrity matter.

Advantages

This 1 m HPE X240 cable offers a compact, direct-attached connection that reduces signal loss and latency compared with longer or multi-component links. The QSFP28 terminations provide compatibility with a wide range of 100G ports, and the cable’s construction is aimed at durability and stable performance in rack and cabinet environments. The product’s design supports high-density deployments, helping to maintain organized cabling and consistent 100 Gigabit performance.

Suitable for (tasks / use cases)

• Direct connections between 100G QSFP28 switches and network interface cards in servers
• Short-reach links within data center racks and between adjacent racks
• High-performance computing clusters using InfiniBand protocols
• Environments requiring low-latency, high-bandwidth links for storage or compute traffic

When it may not be suitable

This cable is designed for short, direct-attached connections and is not intended for long-distance fibre runs or connections that require media conversion or active signal repeaters. It is not appropriate where optical transceivers or single-mode long-haul fibre are required. Additionally, if your infrastructure uses different connector types or lower data rates, a different cable or adapter may be more appropriate.

Key specifications

• Data rate: 100 Gbit/s
• Connector type: QSFP28 to QSFP28, male
• Length: 1 metre
• Supported protocols: InfiniBand and fibre optic 100G links
• Application: short-reach, direct-attached cable for high-density installations

How to use

Install the cable by firmly inserting each QSFP28 connector into the corresponding 100G QSFP28 ports on your switches, adapters or other network devices. Ensure devices are powered down or that hot-swap procedures are followed according to your hardware vendor’s guidance if required. Route the cable to avoid sharp bends and excessive strain; maintain proper airflow in rack configurations. Verify link status and speed in the device management interfaces after connection to confirm a stable 100G link.

What to consider before purchase

• Confirm that both endpoints support QSFP28 100G ports and are compatible with direct-attached copper or equivalent passive/active cable types used
• Verify required cable length and rack/cabinet layout to avoid excess slack or tension
• Check that your network design requires a short-reach direct cable rather than optical transceivers or single-mode fibre

Recommendations

Use this HPE X240 100G QSFP28 1m cable for short, high-bandwidth connections within racks or between adjacent racks. Maintain gentle bend radii, secure cabling to prevent strain, and confirm firmware and port settings on both devices to achieve consistent 100G operation.
