## Summary description

Passive 1 m CBO DAC SFP28-DAC-1M direct attach copper cable for SFP28 ports. Twinax passive design provides a low-latency, short-reach connection at 25 Gbps per lane (SFP28) for switches, NICs and storage devices. Ideal for rack-to-rack or server-to-switch links, simplifies cabling and reduces power compared with optical transceivers.

## Long description

CBO DAC SFP28-DAC-1M is a 1 metre passive twinax copper direct attach cable designed for SFP28 ports. The cable provides a short-reach, low-latency connection supporting 25 Gbps per lane for high-speed links between switches, network interface cards (NICs) and storage devices. Its passive twinax construction offers a straightforward alternative to optical transceivers for short rack-to-rack or server-to-switch connections, with lower complexity and reduced power consumption.
Advantages
The passive twinax design delivers consistent low latency and signal integrity over short distances while eliminating the need for separate optical transceivers and fibers. As a 1 m direct attach solution for SFP28 ports, the cable reduces cabling complexity in dense rack environments and lowers overall power usage compared with active optical or transceiver-based links. The integrated SFP28 connectors ensure plug-and-play compatibility with devices that support SFP28 direct attach copper interfaces.
Suitable for
 Short-reach 25 Gbps connections between servers and top-of-rack switches
 Direct links between NICs and storage arrays within the same rack or adjacent racks
 High-density cabling scenarios where reduced power and simplified setup are priorities
Key specifications
 Connector type: SFP28 form-factor direct attach copper
 Cable type: Passive twinax copper
 Length: 1 metre
 Data rate: 25 Gbps per lane (SFP28)
 Application: Short-reach, rack-to-rack and server-to-switch links
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the two devices to be linked, ensuring that connectors are fully seated and the latches engage. No additional power, transceivers or configuration is required for basic link establishment when devices support SFP28 passive DACs. Verify link status and speed in the device management interface and confirm proper negotiation at 25 Gbps where supported.
Usage recommendations
Use this 1 m passive twinax DAC for short-distance connections within the same rack or between adjacent racks. Avoid sharp bends or excessive pulling force on the cable to maintain signal integrity. For longer distances or where optical isolation is required, consider optical transceivers and fiber cabling instead.
