BlueOptics InfiniBand/fibre optic cable 3 m SFP28 Male/Male 470-ACEV-BL

The BlueOptics InfiniBand/fibre optic cable 3 m SFP28 Male/Male 470-ACEV-BL is a 3-metre direct attach cable with SFP28 connectors designed for short-range, high-speed links in racks and between adjacent racks. It supports 25G data rates and is intended for electrical twinax connections where the transmission protocol and hardware support passive SFP28 DACs. The cable is compatible with common networking equipment and is suitable for Ethernet, FCoE, Fibre Channel and InfiniBand applications at up to 25 Gbit/s over a 3 m distance.

Advantages

This SFP28 Male/Male cable provides reliable high-speed connectivity with low latency and low power consumption typical of passive direct attach twinax solutions. Manufactured to MSA-aligned specifications, it uses established quality components to ensure stable signal integrity and extended service life. The 3 m length is optimized for rack-to-rack and intra-rack connections, allowing straightforward installation without additional transceivers or active components.

Suitable for

• Interconnecting switches and routers within the same rack or adjacent racks
• Linking storage arrays and servers for high-throughput data transfer
• Short-distance InfiniBand, Ethernet, FCoE or Fibre Channel links up to 25 Gbit/s

Key specifications

• Connector type: SFP28 Male to SFP28 Male
• Length: 3 metres
• Data rate: up to 25 Gbit/s
• Cable type: passive direct attach twinax (electrical DAC)
• Designed for short-range rack and adjacent-rack connections

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on the network devices until the latch clicks. Ensure both devices support passive SFP28 DACs and the transmission protocol you intend to use. Route the cable to avoid sharp bends and mechanical strain; keep the cable clear of sources of electromagnetic interference. For equipment requiring firmware or software validation of third-party cables, verify compatibility in the device management interface after connection.

Recommendations

For reliable operation, use this 3 m SFP28 DAC in short-distance links inside racks or between adjacent racks. Confirm that connected hardware explicitly supports passive SFP28 direct attach twinax cables and follow vendor guidance for port configuration and link testing.
