## Summary description

Direct Attach Copper (DAC) SFP28 cable by CBO, model SFP28-DAC-1M, is a 1-meter passive copper twinax designed for direct connections between 25Gb/s SFP28 ports. It provides a low-latency, cost-effective short-reach link for switches, routers and servers without optics. Ideal for data center top-of-rack and server interconnects where fixed short-distance cabling is required.

## Long description

Direct Attach Copper (DAC) SFP28 cable CBO SFP28-DAC-1M is a 1 meter passive twinax cable engineered for direct connections between 25Gb/s SFP28 ports. Designed for short-reach links in data center top-of-rack and server interconnects, this cable eliminates the need for separate optical transceivers and offers a compact, low-latency physical connection suitable for switches, routers and servers that support SFP28 form factor ports.
Advantages
This passive copper DAC cable provides a cost-effective solution for short-distance 25Gb/s links, ensuring low latency and minimal signal processing compared with optical alternatives. Its fixed 1 m length simplifies cabling planning in dense rack environments, reduces power consumption by avoiding active transceivers, and supports plug-and-play installation with native SFP28 port compatibility. The twinax construction delivers consistent electrical performance for direct attach scenarios.
Suitable for (tasks / use cases)
Top-of-rack connections between switches and servers in data centers
Short-distance interconnects between network switches
Direct server-to-switch links in high-density rack deployments
Environments where low latency and reduced power draw are priorities
Key specifications
Connector type: SFP28 to SFP28 passive twinax
Nominal data rate: 25 Gigabit per second per lane (supporting 25Gb/s link)
Length: 1 meter
Cable type: Passive copper twinax
Latency profile: low-latency direct-attach connection
Typical use range: short-reach, within the same rack or adjacent racks
How to use
Insert each SFP28 connector into the corresponding 25Gb/s SFP28 port on the devices to be connected, ensuring the latch mechanism engages. No additional configuration is required at the physical layer; once seated, the devices typically detect the link automatically and negotiate the appropriate transport settings. Verify link status and speed in the host device management interface and route or switch configuration as needed.
Usage recommendations
Use this 1 m passive DAC cable for intra-rack or adjacent-rack connections only. Avoid bending the cable sharply near the connector and maintain recommended bend radii to preserve signal integrity. Ensure both devices support SFP28 passive DAC operation and check firmware or vendor compatibility lists where available.
