## Long description

The CBO SFP28 Direct Attach Copper (DAC) Passive Cable 3 m SFP28-DAC-3M is a 3‑meter passive copper twinax cable designed for short‑reach 25Gbps connections between SFP28 ports in switches, routers and servers. It provides a direct wired link without separate optical transceivers, offering low latency and predictable performance for top‑of‑rack and server interconnect applications where fixed copper cabling is acceptable.
Advantages
This passive SFP28 DAC cable delivers low latency and stable signal integrity for 25Gbps links while reducing total solution cost by eliminating the need for separate transceivers. The integrated SFP28 connectors simplify installation and reduce component count in rack deployments. Its 3 m length is suitable for common data center layouts and short interconnects, providing a straightforward, energy‑efficient alternative to active copper or optical solutions.
Suitable for
Top‑of‑rack switch to server connections in data centers
Inter‑switch links within the same rack or adjacent racks
Server-to-server direct connections for storage or compute clusters
Key specifications
Interface: SFP28 to SFP28
Data rate: 25 Gbps per lane (supporting 25GbE applications)
Length: 3 meters
Cable type: Passive twinax copper
Typical use: Short‑reach direct attach connections
How to use
Connect one integrated SFP28 connector to the SFP28 port on the first device and the other connector to the SFP28 port on the second device. Ensure both devices support passive SFP28 Direct Attach Copper cables and are configured for matching link speed and duplex. No additional transceivers, fiber patching or power is required; once seated properly, the link should negotiate automatically according to the devices' networking settings.
Usage recommendations
Use this passive DAC cable in rack environments where a fixed copper connection is acceptable and distances do not exceed the cable length. Avoid sharp bends or excessive strain on the cable and ensure connectors are fully seated. For longer distances or hot‑plug scenarios that require extended reach or breakaway protection, consider active copper or optical transceiver solutions.
