## Summary description

Passive Direct Attach Copper (DAC) cable CBO AT-SP10TW3, 3 meters long, designed for short-range high-density connections between servers, switches and network devices. This pre-terminated twinax cable provides a cost-effective, low-latency physical link for rack and data-center deployments where fiber is unnecessary. Suitable for 10G/40G class interfaces where passive DAC is supported.

## Long description

The CBO DAC cable AT-SP10TW3 is a 3 meter passive direct-attach copper (twinax) cable designed for short-range, high-density connections between servers, switches and other network devices. Engineered for data-center and rack deployments where fiber is unnecessary, this pre-terminated twinax assembly provides a low-latency physical link suitable for 10G and 40G class interfaces that support passive DAC connections. The cable is intended to simplify connectivity in top-of-rack and middle-of-row installations while maintaining signal integrity over short distances.
Advantages
This passive direct-attach copper cable delivers cost-effective connectivity with minimal power consumption and very low latency compared with active optical transceivers. Being pre-terminated, it reduces installation time and the potential for assembly errors. The twinax construction ensures consistent electrical performance for short-reach links and supports high-density port configurations commonly found in modern server and switch equipment.
Suitable for
 Short-range connections between servers and top-of-rack switches
 High-density data center patching and server clusters
 Rack-to-rack links within the same equipment room where distances do not exceed 3 meters
 10G and 40G interfaces that support passive DAC direct connections
Key specifications
 Length: 3 meters
 Cable type: Passive twinax copper (direct-attach)
 Connector style: Pre-terminated direct-attach ends for compatible 10G/40G ports
 Use case: Short-reach, high-density server and switch interconnects
 Latency: Low, characteristic of passive copper links
How to use
Verify that both network ports on your servers and switches support passive direct-attach copper (DAC) connections and match the interface speed (10G/40G) before installation. Route the 3 m twinax cable within the rack or between adjacent racks, avoiding sharp bends and excessive strain on the connectors. Insert each pre-terminated end firmly into the corresponding port until it seats and latches. After connection, check link indicators on the devices and confirm negotiated speed and link status through the equipment management interfaces.
Usage recommendations
Use this passive DAC cable for short, fixed-length links in environments where fiber optics are not required; avoid installation in runs longer than 3 meters and keep the cable clear of sources of mechanical stress or electromagnetic interference. For reliable long-term operation, follow vendor guidelines for bend radius and connector handling, and perform link verification after installation.
