Product information

Description

Passive DAC cable CBO QSFP28-DAC-0.5M is a 0.5 meter direct-attach copper cable with QSFP28 connectors designed for short-reach interconnects. The cable provides a low-latency, low-power connection between QSFP28 ports on switches, servers and storage systems. Its short length and passive construction make it a cost-effective alternative to optical transceivers for rack-to-rack and in-rack connections in data center environments.

Advantages

This passive QSFP28 direct-attach copper cable offers predictable signal integrity at high data rates while eliminating the need for transceivers and fiber optics in short-distance links. The fixed 0.5 m length reduces clutter and simplifies cable management in dense racks. The passive design consumes no additional power for signal amplification, and QSFP28 connectors ensure compatibility with equipment using the QSFP28 form factor.

Suitable for

  • Short-reach interconnects between QSFP28 ports in data centers
  • Rack-to-rack and in-rack connections where 0.5 m reach is sufficient
  • High-speed links between switches, servers and storage appliances
  • Environments that require low-latency and reduced power consumption

Key specifications

  • Cable type: passive direct-attach copper (DAC)
  • Connector type: QSFP28 on both ends
  • Length: 0.5 meter
  • Data rate: supports 100Gbps aggregate rates over QSFP28 interfaces
  • Form factor: QSFP28 compatible
  • Typical use: short-reach server, switch and storage interconnects

How to use

Insert each QSFP28 connector into the corresponding QSFP28 port until the latch engages. Ensure ports on both devices are powered down or that hot-plug procedures recommended by the equipment vendor are followed during installation if required. After seating the connectors, verify link status through the host devices or management interface. For removal, release the connector latch and pull the cable straight out to avoid damaging the port.

Usage recommendations

Use this 0.5 m passive QSFP28 DAC for short, direct links inside racks or between adjacent racks. Avoid routing the cable near sources of strong electromagnetic interference, and do not exceed the recommended bend radius. Verify device compatibility with QSFP28 passive DACs and consult hardware documentation for supported link settings.
