BlueOptics XS+DA00005-BL InfiniBand fibre optic cable 0.5 m SFP28 Male

The BlueOptics XS+DA00005-BL InfiniBand fibre optic cable 0.5 m SFP28 Male is a short-reach, high-speed connection option designed for data centers and rack-level interconnects. This 0.5 metre cable provides a direct-attach solution with SFP28-compatible connectors and supports up to 25 Gbit/s transmission for Ethernet, FCoE, Fibre Channel and InfiniBand applications where a compact, low-latency link is required. The cable is manufactured to industry MSA standards and is suitable for use with hardware platforms that accept SFP28/direct attach twinax connections.

Advantages

The cable delivers reliable connectivity with low power consumption and minimal latency thanks to its passive twinax design and 30 AWG conductors. Manufactured from high-quality components and tested for compatibility with major vendor hardware, it offers consistent signal integrity and an expected long service life. Its compact 0.5 m length reduces cabling clutter in racks and adjacent-rack links while maintaining the 25G signaling performance required for modern networking and storage systems.

Suitable for

• Short-distance rack-to-rack connections in data centers
• Switch-to-switch and switch-to-router links that accept SFP28 DACs
• Storage arrays and server uplinks using 25GBase-CR or InfiniBand protocols
• High-density network environments where low latency and low power are priorities

Key specifications

• Length: 0.5 metre
• Connector type: SFP28 male to SFP28 male compatible
• Data rate: up to 25 Gbit/s
• Cable type: passive twinax copper, 30 AWG
• Supported protocols: Ethernet (25GBase-CR), FCoE, Fibre Channel, InfiniBand
• Compliance: MSA-compliant design and components

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 slot on the devices to be linked. Ensure both devices support passive direct attach twinax cables and the 25GBase-CR or InfiniBand protocol in use. After seating the connectors, verify link status through device management interfaces and confirm negotiated speed and protocol. Avoid sharp bends and excessive strain on the cable during installation and routing inside racks.

Recommendations

For optimal performance, use this 0.5 m cable for adjacent-rack or short in-rack connections where a fixed, low-latency 25G link is required. Confirm hardware compatibility with SFP28 passive DACs and check firmware or vendor documentation if link negotiation issues appear. Store unused cables coiled without tight loops and avoid exposure to extreme temperatures or physical damage.
