Product information

Description

The CBO QSFP28 Direct Attach Copper (DAC) cable 0.5m is a short-reach, high-bandwidth interconnect designed for 100GbE links between QSFP28 ports in switches, routers and servers. This passive copper assembly provides a direct electrical connection without optical transceivers, enabling low-latency and energy-efficient data transfers in dense rack environments. Its 0.5 metre length suits rack-to-rack or top-of-rack connections where predictable performance and compact cabling are required.

Advantages

This QSFP28-DAC-0.5M cable delivers consistent 100GbE throughput with minimal latency and low power consumption compared with active optical solutions. The integrated QSFP28 connectors provide a stable mechanical fit and straightforward plug-and-play installation. The short length reduces signal attenuation and simplifies cable management in data center racks, while the copper medium eliminates the need for separate optical transceivers, lowering overall link cost.

Suitable for

  • Short-reach 100GbE links between QSFP28 ports in network switches and routers
  • Top-of-rack (ToR) and rack-to-rack interconnects in data centers
  • High-performance server uplinks and aggregation ports
  • Low-latency connections for storage and compute clusters

Key specifications

  • Connector type: QSFP28 to QSFP28
  • Cable medium: Direct attach copper (DAC), passive
  • Length: 0.5 m
  • Data rate: Suitable for 100 Gigabit Ethernet links
  • Latency: Low, direct electrical connection
  • Power consumption: Lower than comparable optical transceiver links

How to use

Insert each QSFP28 connector into the corresponding QSFP28 port on your network devices until the latch clicks into place. Ensure ports are powered down or follow hot-swap guidelines from your equipment vendor if installing into live systems. Verify link status in the device management interface and confirm 100GbE negotiation. For removal, depress the connector latch and withdraw the plug straight out to avoid damaging the port.

Usage recommendations

Use this 0.5m DAC cable for short internal links within racks or between adjacent racks. Avoid excessive bending and secure the cable to prevent strain on QSFP28 connectors. Check device compatibility and firmware support for passive DAC assemblies to ensure full functionality.
