InfiniBand/glasvezelkabel BlueOptics 25G-SFP28-TWX-P-0101-BL 1 m stekker/stekker

The BlueOptics 25G-SFP28-TWX-P-0101-BL is a 1 m InfiniBand/fibre optic solution with SFP28-to-SFP28 male connectors designed for short-range, high-speed links in racks and adjacent rack connections. This passive direct attach twinax cable supports 25GBase-CR electrical transmission at 25 Gbit/s over a 1 metre distance and is compatible with systems that accept SFP28 passive DACs. The cable is intended for use in switches, routers, storage systems and other hardware platforms that support standard SFP28 passive twinax connections and MSA-compliant form factors.

Advantages

This 1 m SFP28 twinax cable provides low latency and low power consumption typical for passive direct attach copper connections. Compliance with common MSA mechanical and electrical standards ensures interoperability with a wide range of network hardware. The construction with high-quality components and 30 AWG conductors delivers stable signal transmission for short-distance 25G applications while keeping installation and maintenance simple.

Suitable for

• Short-range 25G interconnects inside racks and between adjacent racks
• High-density switch-to-switch or switch-to-server connections
• Fibre Channel, Ethernet and InfiniBand links at 25 Gbit/s where passive SFP28 DACs are supported
• Data center and enterprise network environments requiring cost-effective direct attach cabling

Key specifications

• Connector type: SFP28 male to SFP28 male
• Length: 1 metre
• Data rate: up to 25 Gbit/s (25GBase-CR)
• Cable type: passive twinax copper (Direct Attach Cable)
• Wire gauge: 30 AWG
• MSA-compliant mechanical and electrical design
• Typical power consumption: passive (near 0.1 W advantage in system context)

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on the devices to be linked. Ensure both devices explicitly support passive SFP28 DACs and the chosen transmission protocol (Ethernet, Fibre Channel or InfiniBand) at 25G. After insertion, verify link status and negotiated speed in the host device management interface. Route the cable to avoid sharp bends and mechanical strain; the short length is optimized for rack or adjacent-rack runs.

Recommendations

Use this passive 1 m SFP28 twinax cable for short, high-bandwidth links where low latency and low cost are priorities. Confirm device compatibility with passive DACs before deployment and avoid using the cable for distances greater than 1 metre or in environments that require active optical transceivers. For test and validation, check link negotiation and error counters after installation.
