## Summary description

The BlueOptics UACC-DAC-SFP28-1M-BL is a 1 meter InfiniBand/fibre optic cable with SFP28 connectors. It features male/male connectors and is designed for high-speed data transmission, ensuring reliable connectivity for data centers and networking applications.

## Long description

The BlueOptics UACC-DAC-SFP28-1M-BL is a 1 meter InfiniBand/fibre optic cable with SFP28 male-to-male connectors designed for short-reach, high-speed connections in racks and adjacent rack deployments. It implements the 25GBase-CR direct attach twinax copper concept with SFP28 terminations and is intended for reliable electrical signal transfer over a 1 m distance where supported by host hardware. The cable is suitable for Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 25 Gbit/s when used on compatible ports and platforms.
Advantages
This BlueOptics direct attach cable provides a compact, low-latency physical link with passive twinax construction that requires no external power for the cable itself. The SFP28 to SFP28 male connectors allow simple plug-and-play installation in supported SFP28 ports. As a short-length DAC option, it offers low power consumption and a straightforward physical layer without active transceivers, which reduces complexity and potential points of failure in dense rack environments.
Suitable for
Linking switches and routers within a rack or between adjacent racks
Direct server-to-switch or server-to-storage connections over short distances
High-throughput applications such as 25 Gbit/s Ethernet, FCoE, Fibre Channel and InfiniBand
Key specifications
Cable length: 1 meter
Connector type: SFP28 male to SFP28 male
Data rate: up to 25 Gbit/s
Design: passive direct attach twinax copper (DAC)
Wire gauge: 30 AWG
Typical use: short-reach, rack-mounted network interconnects
How to use
Install the cable by inserting each SFP28 male connector into the appropriate SFP28 port on supported switches, routers, servers or storage devices. Ensure both ports officially support passive DAC connections and the 25GBase-CR electrical interface. Avoid excessive bending near the connector ends and secure the cable to prevent strain on the connectors. Verify link status and negotiated speed in the host device management interface after connection.
Usage recommendations
For reliable operation, use this 1 m passive DAC only between compatible SFP28 ports listed as supporting passive direct attach twinax cables or 25GBase-CR in the equipment documentation. Keep the cable within recommended bend radii, avoid repeated flexing, and check firmware or compatibility notes from your hardware vendor if link negotiation fails.
