Product information

Description

CBO QSFP28-DAC-3M is a 3-meter passive copper direct attach cable (DAC) engineered for 100G QSFP28 ports. It establishes a fixed 100 Gigabit link between compatible switches, routers and servers without the need for separate optical transceivers, making it suitable for short-reach, high-bandwidth interconnects in data center environments. The cable is intended for top-of-rack and rack-to-rack connections where a low-latency, power-efficient, and cost-effective 100G connection is required.

Advantages

The passive copper design provides low latency and minimal power consumption compared with active or optical solutions. A pre-terminated QSFP28 form factor ensures straightforward installation and reliable signal integrity over short distances. The cable reduces overall system cost by eliminating separate transceivers while maintaining full 100G line-rate performance for supported ports and equipment.

Suitable for

  • Top-of-rack 100G switch to server connections
  • Rack-to-rack interconnects within the same data hall
  • High-density switch stacking and spine-leaf fabrics
  • Short-reach aggregation links in data center networks

Key specifications

  • Connector type: QSFP28 to QSFP28
  • Length: 3 meters (passive copper)
  • Maximum data rate: 100 Gbps
  • Signal type: Passive copper twinax
  • Typical use-case range: short-reach intra-rack and adjacent-rack cabling
  • Compatibility: QSFP28 ports supporting passive DACs (check device documentation for compatibility)

How to use

Power down or follow hot-plug guidelines of your equipment before insertion if recommended by the vendor. Align each QSFP28 plug with the port and insert until the latch engages; ensure both ends are fully seated. Monitor the device link and interface statistics to confirm a 100G link is negotiated. If connectivity issues arise, verify port settings, check for port compatibility with passive DACs and inspect the cable and connectors for mechanical damage.

Usage recommendations

Use this 3m passive QSFP28 DAC for short-distance 100G links inside racks or between adjacent racks. Avoid routing the cable near high-heat or high-electromagnetic-interference sources, and follow bend-radius and strain-relief practices specified by the equipment vendor to preserve signal integrity and mechanical life.
