BlueOptics QSFP-100G-C5M-BL InfiniBand optický kábel 5 m QSFP28 konektor samec na konektor samec

The BlueOptics QSFP-100G-C5M-BL InfiniBand fibre optic cable is a 5 m QSFP28-to-QSFP28 solution designed for short-range, high-bandwidth connections in data centers and high-performance computing environments. It supports 100 G data rates and is compatible with hardware platforms that accept QSFP28 direct attach links. The cable is intended for reliable, low-latency links between switches, routers, storage systems and server NICs within racks or between adjacent racks.

Advantages

This cable offers 100 G transmission over a 5 metre length with QSFP28 male connectors on both ends, providing a compact and low-power direct attach solution for short-distance interconnects. The passive twinax design yields low latency and minimal power consumption while meeting MSA-compliant mechanical and electrical requirements. Components and manufacturing follow industry standards to ensure stable performance and a long service life in professional network environments.

Suitable for

• Rack-to-rack interconnects in data centre rows
• Connections between switches, routers and storage arrays
• High-performance computing nodes requiring InfiniBand or 100G Ethernet links
• Short-distance links where low latency and low power are priorities

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Nominal data rate: 100 G (supports Ethernet, Fibre Channel, FCoE, InfiniBand up to 100 G)
• Cable type: passive twinax copper direct attach
• Length: 5 metres
• Conductor gauge: 26 AWG
• Form factor: QSFP-100G direct attach cable for short-range interconnects

How to use

Insert each QSFP28 connector into the corresponding QSFP28 port on the devices to be linked, ensuring the latch engages and the connector is fully seated. Confirm that the connected hardware supports passive direct attach twinax QSFP28 modules and the intended protocol (100G Ethernet, InfiniBand, etc.). After physical installation, verify link status and speed through the device management interface and monitor for correct negotiation and error-free operation.

Recommendations

Avoid excessive bending or kinking of the cable and maintain recommended bend radii for twinax assemblies. Use the 5 m direct attach cable for short, intra-rack or adjacent-rack connections where passive QSFP28 DACs are supported by both endpoints. Verify compatibility with the specific switch, router or storage firmware and test a sample link in your environment if interoperability is critical.
