## Summary description

CBO QSFP28-DAC-5M is a 5 meter direct attach copper (DAC) cable with QSFP28 connectors, compatible with IBM equipment. Designed for short-reach 100Gbps connections between switches, routers or NICs with QSFP28 ports, it provides low-latency, energy-efficient links for data centers and rack-to-rack interconnects. Plug-and-play compatibility simplifies installation and reduces cabling costs.

## Long description

CBO QSFP28-DAC-5M is a 5 meter QSFP28 direct attach copper (DAC) cable designed for short-reach 100Gbps links in data center and enterprise network environments. The cable uses QSFP28 connectors at both ends to connect devices with QSFP28 ports and is compatible with IBM equipment. It delivers low latency and low power consumption for rack-to-rack, switch-to-switch or switch-to-server interconnects, and supports plug-and-play installation to simplify deployment and reduce cabling complexity.
Advantages
The QSFP28 direct attach copper construction provides predictable performance for short distances with lower cost compared to active optical solutions. With a 5 m length it covers common rack and aisle distances while minimizing signal loss and power draw. Compatibility with IBM QSFP28 ports ensures interoperability in mixed-vendor environments where hardware validation is required. The cable’s passive design eliminates the need for external power or configuration and supports near-zero setup time.
Suitable for
 100Gbps short-reach connections between switches and routers
 Rack-to-rack or chassis-to-chassis interconnects in data centers
 Direct attachment to servers or NICs with QSFP28 ports
 High-density aggregation and spine-leaf topologies
Key specifications
 Connector type: QSFP28 to QSFP28
 Transmission medium: copper direct attach
 Maximum data rate: 100 Gbit/s
 Cable length: 5 meters
 Typical use: short-reach, within-rack and between-rack interconnects
 Latency: low, passive electrical link
 Power: passive (no external power required)
How to use
Install the DAC cable by inserting each QSFP28 connector into the corresponding port on the devices to be connected. Ensure both ports are powered and configured as required by the host devices; the cable requires no separate drivers or configuration. Route the cable to avoid tight bends and mechanical stress; maintain the specified bend radius to preserve signal integrity. For best performance verify link state and speed on both ends after connection.
Usage recommendations
Use this QSFP28 DAC cable for short, fixed connections where 100Gbps bandwidth and low latency are needed. Avoid using the cable beyond typical rack/aisle distances and do not expose it to extreme temperatures or continuous flexing. When deploying in high-density environments, label both ends and manage cable bundles to maintain airflow and serviceability.
