## Summary description

Passive Direct Attach Copper (DAC) SFP28 cable by CBO, model SFP28-DAC-1M, length 1 meter. Designed for 25Gbps short-reach connections between switches, NICs and servers with SFP28 ports. Offers a compact, low-latency physical connection without optical modules, suitable for data centers and rack-to-rack links where a cost-effective, reliable copper link is required.

## Long description

CBO SFP28 Passive Direct Attach Copper Cable 1m (BlueLAN SFP28-DAC-1M) is a factory-terminated, twin-ax copper twinaxial cable designed for short-reach 25GbE connections between SFP28 ports. The cable provides a direct electrical link without optical transceivers, enabling compact, low-latency interconnects for switches, network interface cards (NICs) and servers in data center topologies and rack-to-rack cabling. The 1 metre length is intended for close-proximity connections in equipment racks and server enclosures, and the robust construction supports reliable signal integrity for 25 Gbit/s links.
Advantages
This passive SFP28 DAC requires no external power or optical modules, which reduces component count and simplifies installation. The direct copper connection delivers low latency and consistent performance at 25Gbps while remaining cost-effective compared with active optical solutions for short distances. The cable assembly is pre-terminated for plug-and-play use with compatible SFP28 ports and is suitable for environments where space is limited and predictable electrical characteristics are needed.
Suitable for
 Short-reach 25 Gigabit Ethernet connections between switches
 Server-to-switch or NIC-to-switch links within racks
 High-density data centre top-of-rack and middle-of-row cabling
 Applications requiring low-latency, short-distance interconnects
Key specifications
 Interface type: SFP28 to SFP28 direct-attach twinax copper
 Nominal data rate: 25 Gbit/s
 Length: 1 metre
 Cable type: Passive twinax copper assembly
 Connector form factor: SFP28 compatible plug
 Typical use: Short-reach rack or chassis interconnects
How to use
Insert each SFP28 plug into the SFP28 port on the two devices to be connected, ensuring the latch engages and the connector is fully seated. No transceiver configuration is required on the cable itself; configure network settings on the connected devices as needed for link negotiation at 25GbE. For best results, route the cable to avoid sharp bends and mechanical strain and confirm link status via the device LEDs or management interface.
Usage recommendations
Use this passive 1m SFP28 DAC for short, direct connections inside racks or between adjacent racks. Avoid exceeding the recommended bend radius and keep the cable away from high-electromagnetic-noise sources. Verify compatibility with the SFP28 ports on your switches and servers before deployment and follow equipment vendor guidance for firmware and supported cable assemblies.
