## Summary description

The BlueOptics ET7302-DAC-0.5M-BL is a high-quality InfiniBand/fibre optic cable designed for efficient data transmission. With a length of 0.5 meters and SFP28 male connectors on both ends, it ensures reliable connectivity for high-speed networking applications.

## Long description

The BlueOptics ET7302-DAC-0.5M-BL InfiniBand/fibre optic cable SFP28 0.5m Male/Male is a 0.5 metre direct attach cable (DAC) with SFP28 male connectors on both ends. It is a passive twinax copper cable designed for short-distance, high-speed links within racks and between adjacent racks. The cable supports 25GBase-CR electrical signalling and is suitable for Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 25 Gbit/s on a 0.5 m span. The construction follows MSA-compliant form factors and uses 30 AWG conductors to provide reliable connectivity for switches, routers, storage systems and other hardware that accept SFP28 passive DACs.
Advantages
This 0.5 m SFP28 DAC offers low latency and low power consumption characteristics typical of passive twinax copper assemblies. It is compatible with common hardware platforms that support 25GBase-CR SFP28 direct attach connections and is produced using industry-grade components to ensure long-term operation and reduced failure rates. The short fixed length simplifies rack cabling, reduces signal attenuation compared with longer copper runs, and provides a cost-effective connectivity option for dense rack environments.
Suitable for
High-speed links between adjacent rack units and within rack enclosures
25GBase-CR connections for switches, routers and top-of-rack devices
Storage and server interconnects using SFP28 ports
Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 25 Gbit/s
Key specifications
Connector type: SFP28 male to SFP28 male
Length: 0.5 metres
Cable type: Passive twinax copper (DAC)
Conductor size: 30 AWG
Supported data rate: up to 25 Gbit/s
Compliance: MSA-compliant SFP28 form factor
Typical application: short-reach rack connectivity
How to use
Install the BlueOptics ET7302-DAC-0.5M-BL by inserting each SFP28 connector into compatible SFP28 ports on the devices to be linked, ensuring the connectors are fully seated and the retaining latches engage. Use the cable for direct electrical signalling between adjacent rack devices or within a single rack where a 0.5 m fixed-length passive DAC meets the equipment requirements. Verify that the connected devices support passive 25GBase-CR DAC operation and check port LEDs or management interfaces for link status after insertion.
Usage recommendations
Use this passive DAC for short, fixed-length links where low latency and low power are priorities; avoid bending the cable beyond the manufacturer’s recommended bend radius and do not use the cable for runs exceeding its 0.5 m length rating. Confirm device compatibility with SFP28 passive DACs before deployment and, where available, test a sample in your target hardware to ensure full functionality.
