## Long description

The BlueOptics ET7302-DAC-1M-BL InfiniBand fibre optic cable SFP28 1m Male Male is a 1 metre direct attach connection designed for high-speed short-reach links in racks and adjacent rack systems. It features SFP28-to-SFP28 connectors and is intended for low-latency, high-bandwidth applications such as 25G Ethernet and InfiniBand-compatible transfers. The cable combines a compact twinax design suitable for dense data-centre deployments with a construction that supports common server, switch and storage platforms that accept passive DAC connections.
Advantages
This 1 m SFP28 cable delivers a reliable electrical direct-attach connection with low latency and minimal power overhead. Its passive twinax construction reduces complexity by avoiding active transceivers, while maintaining compliance with common mechanical and electrical interface standards for short-distance links. The cable's compact form factor and standardized SFP28 connectors make it suitable for tight rack layouts and high-density port configurations.
Suitable for
Short-range connections between switches, routers and servers inside racks
Direct links between adjacent rack units or patch panels
High-bandwidth low-latency fabrics such as 25GBase-CR and compatible InfiniBand deployments
Storage systems and SAN interconnects that support passive DAC cabling
Key specifications
Cable length: 1 m
Connector type: SFP28 to SFP28 (male/male)
Transmission support: up to 25 G per channel (suitable for 25GBase-CR and compatible InfiniBand applications)
Construction: passive twinax copper (30 AWG equivalent twinax conductor)
Colour: black and silver
Weight: approx. 0.08 kg
How to use
Install the BlueOptics ET7302-DAC-1M-BL by inserting the SFP28 connectors into compatible SFP28 ports on the two devices you wish to interconnect. Ensure both devices explicitly support passive direct attach twinax cabling and that the link settings or firmware accept DAC connections. Route the cable to avoid sharp bends and mechanical strain on the connector ends; secure it within the rack to prevent accidental disconnection. No external power or additional transceivers are required for passive operation.
Usage recommendations
Use this cable for short-distance, high-bandwidth connections within the same rack or between adjacent racks. Verify compatibility with the host hardware and, where possible, test a sample link prior to wide deployment to confirm full functionality and link performance in your environment.
