## Summary description

Passive CBO SFP28 direct-attach copper (DAC) cable, 0.5 m length, designed for SFP28 ports supporting 25Gbps connections. Provides a short-range, low-latency link for switches, servers and network appliances without separate transceivers. Ideal for top-of-rack connectivity, data center interconnects and cost-effective short-distance links.

## Long description

Passive CBO SFP28 direct-attach copper (DAC) cable, 0.5 m length, is designed for SFP28 ports that support 25 Gbps connections. This compact, factory-terminated cable provides a short-range physical link between compatible network devices without requiring separate optical transceivers. It is intended for low-latency, high-throughput interconnects in rack-level and data center environments where short-distance, cost-effective cabling is preferred.
Advantages
The passive direct-attach copper design delivers low latency and power-free operation while maintaining reliable 25 Gbps signaling over a half-metre span. Its fixed SFP28 form-factor connectors simplify installation by plugging directly into SFP28 ports on switches, servers and network appliances. The short length reduces clutter and improves airflow in dense rack deployments, and the integrated cable assembly lowers total cost compared with separate transceiver-plus-fiber solutions.
Suitable for
 Top-of-rack switch to server connections
 Short-distance links within data center racks or cabinets
 Interconnects between 25Gbps-capable switches or NICs
 Environments prioritizing low latency and reduced power consumption
Key specifications
 Connector type: SFP28 direct-attach copper
 Data rate: 25 Gbps per lane (supporting 25GbE links)
 Length: 0.5 m
 Cable type: passive copper twinax assembly
 Compatibility: SFP28 ports on switches, servers and NICs that support passive DACs
 Latency: minimal, suitable for latency-sensitive applications
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the two devices to be connected until it latches securely. Ensure both devices support passive SFP28 direct-attach copper cables and are configured for 25GbE operation. No separate transceivers or power sources are required. After connection, verify link status through the device management interface and confirm 25 Gbps negotiated speed. For removal, depress the connector latch and withdraw the cable straight out to avoid stress on the port.
Usage recommendations
Use this 0.5 m passive DAC for short, rack-level connections where cable length is sufficient and passive operation is supported. Avoid routing the cable near high sources of electromagnetic interference and do not exceed recommended bend radius. Check device compatibility lists for passive SFP28 DAC support to ensure proper operation.
