Product information

Description

The BlueOptics AT-QSFP28-2CU-BL is a 2-meter direct attach copper (DAC) cable with QSFP28 connectors on both ends, designed for high-speed links in data center and high-performance computing environments. The cable supports InfiniBand-compatible interconnects and provides a short-reach, low-latency connection between QSFP28 ports. Its black jacket and compact form factor allow clean rack routing while maintaining signal integrity for 100Gbps-class connections where DAC is appropriate.

Advantages

This QSFP28 DAC cable offers a reliable, low-latency physical connection with minimal power consumption compared with active optical alternatives. The fixed 2 m length simplifies planning for adjacent switches or server-to-switch links and reduces the need for additional transceivers. The QSFP28-to-QSFP28 mechanical interface is compatible with devices that accept InfiniBand-style QSFP28 copper interconnects, and the robust black jacket helps protect the internal conductors against wear in rack environments.

Suitable for

  • Short-reach server-to-switch connections in data centers
  • Interconnects in high-performance computing (HPC) clusters
  • InfiniBand fabric links requiring QSFP28 copper cabling
  • Top-of-rack and adjacent-rack connections where 2 m length is sufficient

Key specifications

  • Cable type: Direct attach copper (DAC)
  • Length: 2 m
  • Connectors: QSFP28 to QSFP28
  • Typical application: Short-reach high-speed interconnects (InfiniBand-compatible)
  • Weight: 0.2 kg
  • Colour: Black

How to use

Locate the QSFP28 ports on the devices you intend to interconnect and ensure both ports support DAC copper connections. Align the QSFP28 connectors with the port openings and insert the cable until the latch engages; confirm a secure mechanical fit. After connection, verify link status on each device and configure any required interface settings in the switch or host operating system. For removal, release the connector latch before pulling the cable straight out to avoid damaging the port.

Usage recommendations

Use this 2 m DAC cable for short, direct connections inside racks or between adjacent racks. Avoid tight bends near the connector ends and maintain recommended bend radius for copper cables. Do not exceed the specified cable length for expected signal and performance characteristics; if longer runs are required, consider optical transceivers and fibre cabling. Ensure QSFP28 ports are compatible with passive copper DAC cables before deployment.
