## Summary description

Passive copper DAC cable CBO QSFP28-DAC-5M, 5 meters, designed for direct connection between QSFP28 ports. Provides a low-latency, power-efficient link for 100GbE and other QSFP28-compatible interconnects in switches, routers and servers. Suitable for short-reach rack-to-rack or intra-rack connections where a fixed-length, cost-effective copper solution is required.

## Long description

Passive copper DAC cable CBO QSFP28-DAC-5M is a 5-metre direct attach cable designed for QSFP28 ports. It provides a low-latency, power-efficient physical link for 100GbE and other QSFP28-compatible applications in data centre switches, routers and servers. With a fixed length of 5 m, this cable is intended for short-reach rack-to-rack or intra-rack connections where a simple, cost-effective copper solution is preferred over optical transceivers and fibre.
Advantages
The passive copper construction offers low power consumption and minimal added latency compared with active modules. The integrated QSFP28 connectors eliminate the need for separate transceivers, simplifying installation and reducing overall equipment costs. A 5-metre fixed length reduces cable management complexity and ensures predictable signal performance for short-reach links. The cable is compatible with typical QSFP28 ports found in modern network switches and servers, providing a reliable physical layer connection for high-bandwidth interconnects.
Suitable for
 Short-reach 100GbE connections between adjacent racks
 Intra-rack uplinks in high-density switch deployments
 Direct server-to-switch or switch-to-switch links within the same rack row
 Applications where low power and low latency are priorities
Key specifications
 Connector type: QSFP28 to QSFP28
 Cable type: Passive copper direct attach
 Length: 5 metres
 Supported link speed: 100GbE (QSFP28)
 Typical use case: Short-reach rack-to-rack or intra-rack interconnects
 Latency: Minimal added latency typical of passive copper DACs
How to use
Install the cable by inserting each QSFP28 connector into the corresponding port until it clicks into place, ensuring orientation is correct and ports are powered down or handling hot‑plug according to your equipment documentation. Verify link status indicators on the connected devices and configure network interfaces as required. For best results, route the cable to avoid tight bends and mechanical stress and maintain proper airflow within the rack.
Usage recommendations
Use this passive DAC for short-reach links up to 5 m where cost-efficiency, low latency and low power consumption are required. Avoid deploying in environments that exceed the recommended bend radius or expose the cable to excessive mechanical strain, and confirm compatibility with the QSFP28 ports on your equipment before installation.
