## Summary description

Direct Attach Copper (DAC) SFP28 cable by CBO, model SFP28-DAC-1M, 1 meter length. A passive copper twinax cable designed for short-reach 25GbE interconnects between SFP28 ports in switches, servers and NICs. Provides low-latency, power-efficient connectivity for rack-level connections and top-of-rack deployments.

## Long description

BlueOptics SFP28 passive DAC copper cable SFP28-DAC-1M is a 1 metre direct attach twinax cable engineered for short-reach 25GbE connections. The cable terminates in SFP28 form-factor plugs and is intended for use between SFP28 ports on switches, servers and network interface cards. As a passive copper assembly, it provides a low-latency, low-power physical link suitable for rack-level and top-of-rack interconnects where distances are within the cable’s 1 m length.
Advantages
This passive DAC cable offers deterministic latency and minimal signal processing since no active electronics are required in the cable itself. The direct copper twinax construction delivers energy efficiency compared with optical transceivers for short distances and simplifies cabling at the rack level. Its SFP28 connectors ensure compatibility with standard 25GbE SFP28 ports, and the fixed 1 m length keeps connections tidy and predictable in dense installations.
Suitable for
 Short-reach 25GbE links between rack-mounted switches and servers
 Top-of-rack connectivity in data center racks
 Direct links between SFP28-capable NICs and switches
 High-performance computing clusters requiring low-latency interconnects
Key specifications
 Connector type: SFP28 form-factor on both ends
 Cable type: passive copper twinax
 Data rate: designed for 25 Gigabit Ethernet (25GbE)
 Length: 1 metre
 Typical use: short-reach, rack-level interconnects
 Power profile: passive (no in-line electronics)
How to use
Insert each SFP28 connector into the SFP28 port of the devices you wish to connect, ensuring the latch clicks into place for secure seating. Verify link status on each device and configure network settings according to your infrastructure requirements. Because the cable is passive, no additional power or configuration is required at the cable level. Handle the cable by the connectors when seating or removing to avoid strain on the twinax assembly.
Usage recommendations
Use this passive DAC cable for connections within the same rack or between adjacent racks where the 1 m length is sufficient. Avoid routing the cable through sharp bends or tightly wound paths; maintain the manufacturer’s minimum bend radius to preserve signal integrity. Confirm compatibility with the SFP28 ports on your network equipment and consult device documentation for supported passive DAC assemblies if required.
