## Summary description

CBO DAC cable SFP28-DAC-1M is a 1 meter passive copper direct attach cable for SFP28 ports. Designed for short-distance high-speed connections between switches, servers and NICs supporting 25Gbps SFP28 interfaces. Provides low-latency, low-power wired connectivity without additional transceivers, suitable for data centers and rack-to-rack links.

## Long description

CBO DAC cable SFP28-DAC-1M is a 1 meter passive copper direct attach cable that connects SFP28 ports for short-distance 25Gbps links. Intended for rack-to-rack and intra-rack connections in data centers, this BlueOptics cable eliminates the need for separate transceivers and delivers low-latency, low-power wired connectivity between switches, servers and network interface cards that support SFP28. The compact, fixed-length assembly simplifies installation and reduces component count in dense switch environments.
Advantages
The passive copper design provides energy-efficient 25Gbps performance with minimal heat generation and reduced power consumption compared with active optics. Using a direct attach cable removes transceiver modules from the link, lowering overall cost and simplifying inventory management. At 1 meter length the cable is optimized for short-range links inside racks or between adjacent racks, offering predictable signal performance and low latency for latency-sensitive applications.
Suitable for
Short-distance connections between switches and top-of-rack equipment
Server to switch links inside data center racks
High-density network deployments requiring low-latency 25Gbps links
Environments where power efficiency and reduced heat are important
Key specifications
Interface: SFP28 to SFP28 direct attach
Length: 1 meter
Transmission speed: 25 Gbps per lane (SFP28 standard)
Media type: passive copper twinaxial cable
Typical use: short-range, up to rack-to-rack and intra-rack links
Latency: low, suitable for latency-sensitive traffic
Power profile: passive (no active components or external power)
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the two devices to be linked. Ensure ports are powered off or administratively down if required by the host equipment’s installation policy, then enable the interfaces after physical installation. Verify link negotiation and speed settings on both devices and check that the network interface recognizes the direct attach connection as a 25Gbps link. Route the cable to avoid sharp bends and mechanical stress; the fixed 1 m length is intended for close-proximity connections.
Usage recommendations
Use this 1 m passive DAC for intra-rack or adjacent-rack 25Gbps links where a simple, low-power connection is required. Avoid using passive DACs beyond their recommended short-range limits and follow equipment vendor guidance for compatibility with SFP28-based interfaces.
