BlueOptics X66240A-2-BL InfiniBand/kuitu-kaapeli 2 m SFP28 musta

The BlueOptics X66240A-2-BL is a 2-meter InfiniBand / fibre optic cable with SFP28 connectors on both ends, designed for short-distance, high-speed links in racks and adjacent rack connections. The cable is presented in black and is intended for reliable data transmission in data centers and networking environments. It is compatible with systems that support SFP28 interfaces and 25GBase-CR electrical applications when used as a direct-attach twinax solution.

Advantages

The cable combines a compact SFP28 connector interface with a 2 m length that fits rack-to-rack and in-rack topologies. As a passive direct-attach option for short distances, it offers low latency and low power consumption. The black jacket provides a durable finish and simple integration into existing cabling layouts. The product is manufactured to industry MSA guidelines and is tested for compatibility with major hardware platforms that accept the corresponding 25GBase-CR SFP28 direct-attach cables.

Suitable for

• Connecting switches and routers within the same rack or adjacent racks
• Short-distance server-to-switch or storage-to-switch links
• InfiniBand and other 25 Gbps-capable environments that use SFP28
• Data center deployments requiring passive direct-attach twinax copper connections

Key specifications

• Connector type: SFP28 on both ends
• Length: 2 meters
• Transmission: supports up to 25 Gbps applications (25GBase-CR compatible)
• Cable type: passive direct-attach twinax copper for short-range electrical signal transfer
• Cable gauge: 30 AWG
• Jacket color: black

How to use

Install the cable by plugging each SFP28 connector firmly into the SFP28 ports of the devices to be linked, ensuring the connectors are oriented correctly and latched. Use this 2 m passive direct-attach twinax cable for short-range links inside racks or between adjacent racks. Verify that the connected hardware supports passive 25GBase-CR / SFP28 direct-attach cables and that firmware or software settings allow operation at 25 Gbps where applicable. Avoid sharp bends and excessive pulling force on the cable to maintain performance and mechanical integrity.

Recommendations

For reliable operation, use the cable within its intended short-distance range and in environments where devices explicitly support passive SFP28 direct-attach twinax cables. Keep the cable away from strong electromagnetic sources and maintain proper rack routing to prevent mechanical stress. If interoperability with specific vendor hardware is required, test a sample connection to confirm compatibility before large-scale deployment.
