## Summary description

CBO CPAC-DAC-40G-3M is a 3-meter direct-attach copper (DAC) cable designed for 40Gbps data connections. It provides a fixed-length, low-latency link for switches, servers and network appliances supporting 40G interfaces. The passive copper assembly offers reliable short-reach connectivity, simplifies rack cabling and reduces power and module costs compared with optical transceivers.

## Long description

CBO CPAC-DAC-40G-3M 40Gbps 3m direct-attach copper is a 3-meter passive direct-attach copper (DAC) cable engineered for 40Gbps short-reach links between switches, servers and network appliances. The fixed-length twin-ax assembly provides low latency and consistent signal performance for data center top-of-rack and adjacent-rack connections. As a copper direct-attach solution, it removes the need for separate optical transceivers and fiber patching for short distances, helping to simplify cabling and reduce power consumption and module costs.
Advantages
The cable delivers a reliable 40Gbps physical connection with minimal insertion loss and low latency appropriate for high-throughput applications. Its passive copper design eliminates the need for active electronics, lowering power usage and heat generation in comparison to optics-based alternatives. The fixed 3 m length ensures predictable signal behaviour and simplifies rack planning, while the robust twin-ax construction supports repeated installation cycles in dense rack environments.
Suitable for
 Top-of-rack switch-to-server connections in data centers
 Inter-switch links within the same rack or adjacent racks
 High-throughput appliance connections requiring 40Gbps interfaces
 Short-reach cabling scenarios where optical transceivers are not required
Key specifications
 Data rate: 40 Gbps
 Length: 3 meters
 Cable type: Passive direct-attach copper (twin-ax)
 Connector type: 40G-compatible direct-attach connectors for QSFP+ style ports
 Use case: Short-reach, rack-level connectivity
How to use
Install the DAC cable by inserting each connector into the corresponding 40G-capable port on your switch, server or network appliance until the latch engages. Ensure both devices support passive direct-attach copper connections at 40Gbps. Route the 3 m cable within the rack to avoid sharp bends and to maintain proper airflow. No additional transceivers, fiber patch cords or power connections are required.
Usage recommendations
For reliable operation, verify port compatibility and firmware support for passive 40G DACs on both ends prior to deployment. Keep bend radius within manufacturer guidance and avoid exposing the cable to excessive mechanical strain or temperatures outside typical data center ranges.
