InfiniBand/fibre optic cable BlueOptics X66240A-1-BL 1 m SFP28

The BlueOptics X66240A-1-BL is a 1 m InfiniBand/fibre optic cable equipped with SFP28 connectors on both ends. Designed for short-reach, high-speed links in data centers and rack environments, this cable supports 25 Gbit/s data rates and provides a direct connection between switches, servers and storage devices. It is built to meet MSA compatibility requirements and to work with major networking platforms that accept SFP28 direct-attach connections.

Advantages

The cable offers low latency and reliable signal transmission for demanding networking applications. Its 1 m length is suited for connections within or between adjacent racks, reducing clutter and signal loss compared with longer runs. Constructed according to commonly accepted assembly standards, the cable uses SFP28-to-SFP28 terminations for straightforward insertion into compatible ports and is suitable for Ethernet, Fibre Channel, FCoE and InfiniBand environments where 25G performance is required.

Suitable for

• Short-reach connections between switches and servers in a rack
• Interconnects between adjacent racks in data center deployments
• Linking storage arrays, routers and NICs with SFP28 ports
• 25G Ethernet, FCoE, Fibre Channel and InfiniBand links

Key specifications

• Connector type: SFP28 to SFP28
• Length: 1 meter
• Supported data rate: up to 25 Gbit/s
• Cable type: direct-attach twinax copper (passive) suitable for short distances
• Wire gauge: 30 AWG
• MSA-compliant interface

How to use

Install the BlueOptics X66240A-1-BL by inserting each SFP28 plug into the corresponding SFP28 port until the latch clicks. Ensure both connected devices support passive 25G direct-attach twinax copper cables and the selected transmission protocol. Route the cable to avoid sharp bends and mechanical stress; the 1 m length is intended for short, point-to-point links inside racks or between adjacent racks. No external power is required for passive operation. Verify link status on connected devices after insertion and confirm negotiated speed and protocol compatibility in the host system or switch management interface.

Recommendations

Use this 1 m SFP28 direct-attach cable for short-distance, high-speed interconnects where a passive twinax solution is supported. Avoid exceeding the recommended bend radius and maintain secure seating of SFP28 plugs. For cross-vendor environments, confirm compatibility with the end equipment and the supported protocols before deployment.
