## Summary description

Direct-attach copper cable (DAC) CBO SFP28-DAC-1M is a 1 m passive twinax cable designed for SFP28 ports. It provides a short-reach, low-latency 25Gbps connection between compatible switches, network interface cards and servers. Suitable for rack-to-rack or within-rack links where cost-effective, energy-efficient cabling is needed.

## Long description

CBO SFP28 passive copper DAC cable SFP28-DAC-1M is a 1 m direct-attach twinax cable for SFP28 ports, engineered for short-reach 25Gbps links. The passive design requires no additional power or active electronics, delivering a low-latency physical connection between compatible switches, network interface cards and servers. This cable is intended for cost- and energy-conscious deployments where reliable, short-distance connectivity is needed within racks or between adjacent racks.
Advantages
The CBO SFP28 passive twinax provides a stable 25Gbps channel with minimal signal processing overhead, offering low latency and consistent performance for high-throughput applications. Its 1 m length minimizes excess cable slack in dense rack environments and simplifies cable management. Being a passive direct-attach solution, it consumes no additional power compared with active modules and reduces total system cost while maintaining interoperability with standard SFP28 ports.
Suitable for
 Rack-to-rack short-distance 25Gbps links in data centers
 Within-rack connections between switches, servers and NICs
 High-throughput, low-latency applications such as virtualization and storage networks
 Cost-sensitive environments that favour energy-efficient cabling
Key specifications
 Connector type: SFP28 direct-attach twinax
 Data rate: 25 Gbps per channel
 Cable type: Passive copper twinax
 Length: 1 meter
 Use case: Short-reach, within-rack and adjacent-rack connections
 Latency: Low, due to passive direct-attach design
How to use
Insert each SFP28 connector into the corresponding SFP28 port on your switch, server or network interface card until it latches. Ensure both ends are connected to compatible SFP28 ports configured for 25Gbps operation. No external power or transceivers are required. Verify link status on the connected devices and confirm that interface settings (speed and duplex where applicable) match the intended 25Gbps operation. Route the cable to avoid sharp bends and excessive tension to maintain signal integrity.
Usage recommendations
For reliable performance, use this passive DAC for short-distance links up to 1 m in rack or adjacent-rack deployments. Avoid tight bends and mechanical stress, and ensure compatibility with your equipment vendor’s SFP28 port support. In high-density deployments, document cable locations and secure cables to prevent accidental disconnection.
