BlueOptics 25G-SFP28-TWX-P-0.5M-BL InfiniBand fibre optic cable 0.5m SFP28 Male/Male

The BlueOptics 25G-SFP28-TWX-P-0.5M-BL is a 0.5 meter high-speed connectivity cable with SFP28 connectors on both ends. It supports 25G data rates and is designed for short-reach connections in rack environments, data centers and high-performance computing setups. The cable follows MSA-compliant form factors for SFP28 interfaces and is intended for direct attach scenarios where low latency and reliable electrical signal transmission are required.

Advantages

This 0.5 m SFP28-to-SFP28 cable provides a compact, low-latency connection suitable for interconnecting switches, routers and storage devices in adjacent rack units. As a passive direct attach solution with twinax construction, it offers low power consumption, minimal signal loss over short distances and a simple design that reduces potential points of failure. Components are selected for compliance with common industry standards to ensure interoperability and consistent performance in supported hardware platforms.

Suitable for

• Short-reach 25G links between rack-mounted switches and servers
• Connections between top-of-rack and adjacent rack equipment
• High-performance computing and clustered storage interconnects
• Data center environments requiring low-latency, low-power links

Key specifications

• Connector type: SFP28 male to SFP28 male
• Length: 0.5 meter
• Supported data rate: up to 25 Gbit/s
• Cable type: passive direct attach twinax copper
• Wire gauge: 30 AWG
• Applications: Ethernet, FCoE, Fibre Channel, InfiniBand (protocol dependent)

How to use

Insert each SFP28 connector firmly into the corresponding SFP28 ports of the devices to be linked, ensuring the latch engages. Use the cable for short-distance electrical connections inside racks or between adjacent racks; do not exceed the specified 0.5 m length for reliable 25G operation. Verify that the connected hardware platform supports passive DAC SFP28 direct attach cables and that the firmware or software settings permit the link. No external power or transceiver modules are required for passive operation.

Recommendations

Avoid sharp bends and excessive pulling force on the cable; maintain a bend radius consistent with 30 AWG twinax construction. Confirm device compatibility and, if possible, test a sample link before large-scale deployment to ensure full functionality with your specific hardware and firmware versions.
