InfiniBand/fibre optic cable BlueOptics 470-ABOV-BL 1 m QSFP28 Male/Male

The BlueOptics 470-ABOV-BL is a 1 m InfiniBand/fibre optic direct attach cable with QSFP28 male connectors on both ends. Designed for short-reach, high-speed links in racks and between adjacent racks, this cable supports up to 100 Gbps data rates and is suitable for Ethernet, FCoE, Fibre Channel and InfiniBand protocols where a passive QSFP28-to-QSFP28 connection is supported. The cable uses a twinax copper assembly with 30 AWG conductors and follows MSA-compliant QSFP28 mechanical and electrical specifications to ensure interoperability with compatible hardware platforms.

Advantages

This 1 m QSFP28 male-to-male cable provides a simple, low-latency connection for short-distance high-bandwidth applications without active electronics. The passive direct attach design offers low power consumption and reduced points of failure compared with active modules. MSA compliance and the use of industry-standard components contribute to long operational life and broad compatibility with switches, routers and storage systems that accept QSFP28 passive twinax assemblies.

Suitable for

• Short-reach 100G links inside racks and between adjacent racks
• High-bandwidth interconnects for switches and routers supporting QSFP28
• Direct attach connections for storage arrays and server NICs
• Environments using Ethernet, FCoE, Fibre Channel or InfiniBand at up to 100 Gbps

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable length: 1 metre
• Transmission: Passive twinax copper
• Data rate: Up to 100 Gbps (protocol-dependent)
• Wire gauge: 30 AWG
• Compliance: MSA-compliant QSFP28 mechanical/electrical profile

How to use

Verify that both ports on your devices support passive QSFP28 direct attach twinax cables and the intended protocol (Ethernet, FCoE, Fibre Channel or InfiniBand). Power down or follow hot-plug guidelines from your equipment vendor, then insert each QSFP28 connector into the corresponding port until the latch engages. Ensure cables are routed without sharp bends and secured to avoid strain on connectors. If required by your platform, confirm link status and negotiate link speed using the device management interface.

Recommendations

Use this cable for short interconnects where low latency and low power are priorities. Avoid extended runs beyond the specified 1 m length and do not substitute for active optical transceivers when longer distances or optical fiber are required. Inspect connector latches before installation and store the cable in a clean, dry environment when not in use.
