InfiniBand/optický kabel BlueOptics X66130-1-BL 1 m SFP28

The BlueOptics X66130-1-BL 1 m InfiniBand/fibre optic cable with SFP28 connectors on both ends is a short-reach interconnect designed for high-speed links in racks and adjacent racks. It supports 25G data rates and is suitable for use where low latency and reliable signal integrity are required. The cable is constructed to meet common MSA-based mechanical and electrical requirements and is compatible with equipment that supports SFP28 25GBase-CR connections.

Advantages

This 1 m cable provides a compact, low-latency connection for switches, storage systems and servers where a direct attach or short optical/fibre solution is needed. Its SFP28 interface on both ends ensures native compatibility with 25G ports that accept SFP28 modules or direct-attach assemblies. The passive twinax or fibre construction minimizes power consumption and system complexity, while the cable's design and component selection aim to deliver long service life and consistent signal performance for demanding data-centre environments.

Suitable for

• Interconnecting top-of-rack switches and aggregation switches across adjacent racks
• Direct connections between servers and storage arrays supporting 25G SFP28
• Short-distance InfiniBand and Ethernet links (25G)
• Test and lab environments requiring reliable 1 m links

Key specifications

• Connector type: SFP28 on both ends
• Cable length: 1 meter
• Supported data rate: up to 25 Gbit/s
• Cable type: passive direct-attach twinax copper / compatible short-reach fibre optic construction (depending on variant)
• Wire gauge (twinax variant): 30 AWG
• Transmission protocols: Ethernet, FCoE, Fibre Channel and InfiniBand at supported data rates
• Design: MSA-compliant mechanical and electrical characteristics

How to use

Install the BlueOptics X66130-1-BL by inserting the SFP28 connector plugs into compatible SFP28 ports on your switches, routers, servers or storage devices. Ensure both ends are fully seated and latched according to the host equipment’s guidance. For passive twinax copper usage, confirm that the connected devices support passive DAC operation and the intended 25G protocol. After physical installation, verify link status and negotiated speed in your network management interface and monitor signal performance to confirm stable operation.

Recommendations

Use this 1 m SFP28 cable for short, direct links inside racks or between adjacent racks where 25G connectivity is required. Avoid excessive bending or tight cable bundles near the connector to preserve signal integrity. For longer runs or where optical isolation is required, select appropriate SFP28 optical transceivers and fibre patch cabling instead.
