InfiniBand/fibre optic cable BlueOptics 10522-BL 5 m SFP28 Male/Male

The BlueOptics 10522-BL is a 5 m InfiniBand/fibre optic cable with SFP28 connectors on both ends, designed for high-speed short-reach connections in racks and between adjacent racks. It supports data transmission rates up to 25 Gbit/s and is compatible with hardware that accepts SFP28 direct-attach or InfiniBand interfaces. The cable is intended for use in data centers, server rooms and networking equipment where low-latency, reliable links are required.

Advantages

The cable combines a compact SFP28-to-SFP28 form factor with a 5 m length suitable for rack-to-rack or intra-rack connections. Its passive twinax construction provides low latency and low power consumption while maintaining signal integrity for 25G applications. Manufactured to MSA-compliant interfaces and assembled with high-quality components, the product targets long service life and broad interoperability across major switch, router and storage platforms that support the corresponding SFP28 or InfiniBand DAC specifications.

Suitable for

• Short-reach server-to-switch and switch-to-switch connections in racks
• 25G Ethernet, FCoE and InfiniBand short-distance links
• High-density data center cabling and top-of-rack deployments
• Storage area network connections and aggregation links

Key specifications

• Connector type: SFP28 male to SFP28 male
• Cable length: 5 meters
• Supported data rate: up to 25 Gbit/s
• Media type: passive twinax copper (Direct Attach Cable)
• Wire gauge: 30 AWG
• MSA-compliant SFP28 electrical and mechanical interface
• Low latency and low power consumption characteristic of passive DACs

How to use

Insert each SFP28 connector into the corresponding SFP28 port on your networking device until the latch engages. Ensure both devices support passive SFP28 direct-attach cables and the selected protocol (25G Ethernet, FCoE or InfiniBand). Route the cable to avoid sharp bends and mechanical stress; maintain the recommended bend radius for twinax cable assemblies. No external power or transceivers are required for passive operation. After insertion, verify link status and negotiated speed on both connected devices according to the vendor's interface diagnostics.

Usage recommendations

Use this 5 m SFP28 DAC for short, fixed connections inside racks or between adjacent racks. Verify device compatibility and firmware support for passive DAC operation before installation. Avoid excessive bending, pulling or repeated unplugging to prolong service life.
