Product information

Description

CBO QSFP28-DAC-1M is a 1-meter passive copper direct attach cable with QSFP28 connectors engineered to support 100Gbps links. The cable is intended for short-range, high-speed interconnects between network devices such as switches, routers and servers. Its passive design provides low latency and plug-and-play installation while the compact form factor helps optimize space in data center topologies and server racks.

Advantages

The passive copper construction delivers reliable 100Gbps throughput with minimal signal processing, reducing power consumption compared with active optical alternatives. QSFP28 connectors ensure compatibility with devices that accept QSFP28 form-factor transceivers and the 1 m length is suitable for direct connections inside racks or between adjacent racks. The cable’s flexibility and small cross-section simplify cabling management and help maintain airflow in dense installations.

Suitable for

  • Short-reach connections between switches and aggregation devices within a rack
  • Direct links from servers to top-of-rack switches
  • High-performance computing clusters requiring low-latency interconnects
  • Data centre patching where cost-efficient 100Gbps links are needed

Key specifications

  • Connector type: QSFP28 to QSFP28
  • Length: 1 meter
  • Media: passive copper twinax
  • Data rate: 100 Gbit/s
  • Form factor: direct attach cable suitable for QSFP28 ports
  • Typical use: short-range, in-rack or adjacent rack connections

How to use

Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port on the network devices until it latches. Ensure that both devices are powered down or follow hot‑plug guidelines from the device manufacturer if connecting live. After physical connection, verify link status through device management interfaces and monitor for expected 100Gbps link negotiation. Route the cable to avoid sharp bends and maintain recommended bend radius for copper twinax to prevent performance degradation.

Usage recommendations

Use this passive DAC for reliable, short-distance 100Gbps links inside racks or between adjacent racks. Avoid extended runs beyond the recommended distance for passive copper and ensure ports explicitly support QSFP28 direct attach cables. For longer distances or electrical noise-sensitive environments, consider active or optical alternatives.
