Product information

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.
