BlueOptics XQ+DA0001-BL InfiniBand fibre optic cable 1 m QSFP28 Male Male

The BlueOptics XQ+DA0001-BL InfiniBand fibre optic cable 1 m QSFP28 Male Male is a short-reach high-speed interconnect designed for use in data centres and rack environments. Featuring QSFP28 connectors on both ends and a 1 metre length, the cable supports 100 Gbps class applications such as Ethernet, FCoE and InfiniBand where a reliable, low-latency link is required between adjacent devices. The cable is intended for direct connectivity between switches, routers, storage systems and other compatible hardware that accept QSFP28 interfaces.

Advantages

This 1 m QSFP28-to-QSFP28 cable provides a compact, passive direct-attach solution that minimises latency and power consumption compared with active optical transceivers. It is MSA-compliant and built using high-quality components to ensure compatibility and long service life in professional networking environments. Its short length reduces signal degradation and is suitable for rack-to-rack or within-rack connections where 100G performance is required.

Suitable for

• Direct interconnects between switches and routers within the same rack or adjacent racks
• High-performance storage area networks using Fibre Channel or FCoE at up to 100 Gbps
• Compute clusters and InfiniBand fabrics requiring low-latency links
• Upgrades or replacements of QSFP28 100G links in data centre infrastructure

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Nominal data rate: supports 100 Gbps-class applications (Ethernet, FCoE, Fibre Channel, InfiniBand)
• Length: 1 metre
• Cable type: passive direct attach (twinax copper in equivalent DAC implementations or short-reach direct attach solution)
• Compliance: MSA-compliant QSFP28 interface
• Typical use case: short-reach rack/adjacent-rack connections with low latency and low power

How to use

Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port on the two devices until the latch engages. Verify that both devices recognise the link and that the interfaces are configured for the intended protocol and speed (for example, 100GBase-CR4 or the appropriate InfiniBand/Fibre Channel setting). Ensure rack cabling is routed to avoid undue strain on the connectors and that bend radii are observed for the cable type in use. For passive direct-attach solutions, confirm that the connected hardware supports passive QSFP28 DACs.

Lietošanas ieteikumi

Use the cable for short-distance, high-bandwidth connections inside racks or between adjacent racks, keep it free from mechanical stress and avoid exceeding recommended bend radii. Before deployment, check device compatibility with QSFP28 passive direct-attach cables and validate link speed and protocol in a test environment if required.
