## Summary description

The BlueOptics ET7302-DAC-3M-BL is a 3-meter InfiniBand fibre optic cable with SFP28 connectors. It features male-to-male connections, ensuring high-speed data transmission for networking applications. This cable is ideal for data centers and high-performance computing environments, providing reliable connectivity and low latency.

## Long description

The BlueOptics ET7302-DAC-3M-BL InfiniBand fibre optic cable SFP28 3m Male/Male is a 3-metre direct attach cable designed to provide high-speed, short-reach connectivity between SFP28 ports. It supports up to 25 Gbit/s data rates and is intended for use in rack-mounted equipment such as switches, routers and storage systems. The cable uses SFP28-to-SFP28 connectors and a passive twinax design appropriate for electrical signal transmission over a 3 m distance while meeting MSA-compatible mechanical and electrical requirements.
Advantages
This 3 m SFP28 direct attach cable offers low latency and low power consumption compared with active optical transceivers, making it suitable for dense data-centre topologies and high-performance computing links. The passive twinax construction reduces complexity and potential points of failure, and components are selected to meet common industry MSA standards for SFP28 connectivity. Its compact form factor enables straightforward routing inside racks and between adjacent racks.
Suitable for
Short-reach uplinks between rack servers and top-of-rack switches
Direct links between switches, routers and storage arrays supporting SFP28
High-performance computing interconnects and InfiniBand-capable hardware
Environments requiring low-latency, cost-effective 25G connectivity
Key specifications
Connector type: SFP28 to SFP28 (male/male)
Length: 3 metres
Data rate: up to 25 Gbit/s
Cable type: passive twinax (30 AWG)
Transmission: electrical signals for short-distance links
Compliance: MSA-compatible mechanical and electrical characteristics
How to use
Connect each SFP28 plug to the corresponding SFP28 port on your devices, ensuring both ends are fully seated and latched. Use the cable for short-distance interconnects within or between adjacent racks; avoid routing beyond the specified 3 m length to maintain signal integrity. Verify that the host devices support passive DAC twinax cables and the 25GBase-CR protocol in their firmware or hardware compatibility lists before deployment.
Usage recommendations
For reliable operation, keep the cable free from sharp bends and kinks and maintain bend radii recommended by the device vendors. Use this cable in rack-top or adjacent-rack connections and check device compatibility lists if deploying in heterogeneous hardware environments.
