## Summary description

Passive SFP28 direct attach copper (DAC) cable by CBO, model SFP28-DAC-5M-CN-BL, 5 meters, Male-to-Male connectors, supporting 25 Gbit/s data rates. Designed for short-reach server, switch and storage interconnects, it offers low-latency, power-efficient connectivity between SFP28 ports. Suitable for rack-to-rack or intra-rack connections in data centers.

## Long description

The CBO SFP28 Direct Attach Copper Cable SFP28-DAC-5M-CN-BL is a 5 meter passive copper cable with SFP28 male connectors on both ends, designed for 25 Gbit/s links between compatible SFP28 ports. Intended for short-reach interconnects in data centers, the cable supports rack-to-rack and intra-rack connections between servers, switches and storage devices. Its passive design requires no external power and delivers low latency and low power consumption compared with optical transceivers for equivalent short distances.
Advantages
This direct attach copper cable provides a cost-effective and power-efficient way to connect SFP28 ports at 25 Gbit/s over short distances. The fixed 5 m length simplifies cabling planning for rack and adjacent-rack deployments, while the male-to-male SFP28 connectors ensure direct compatibility with SFP28 cages. The passive copper medium reduces link negotiation complexity and offers predictable latency and signal behavior for latency-sensitive applications.
Suitable for
Short-reach server-to-switch or switch-to-switch links within racks
Storage array connections where 25 Gbit/s performance is required
Top-of-rack and adjacent-rack cabling in data center environments
Environments prioritizing low latency and reduced power consumption
Key specifications
Connector type: SFP28 male to SFP28 male
Length: 5 meters
Data rate: up to 25 Gbit/s
Medium: passive copper twinax cable
Typical application: short-reach interconnects (intra-rack, rack-to-rack)
Latency: low, suitable for latency-sensitive links
Power: passive design with no external power module required
How to use
Install the cable by inserting each SFP28 connector into the corresponding SFP28 port until it latches. Ensure that both devices support SFP28 passive DAC cables and that firmware or vendor compatibility requirements are met. Route the cable to avoid sharp bends and excessive strain; maintain the specified 5 m length without tension. Verify link status through the connected devices' management interfaces and monitor signal and error counters after installation to confirm reliable operation.
Usage recommendations
Use this 5 m passive SFP28 DAC for short-distance links inside racks or between adjacent racks where 25 Gbit/s bandwidth and low latency are required. Avoid using the cable in longer-distance runs or environments with heavy electromagnetic interference; for longer reaches or electrically noisy environments, consider active copper solutions or optical transceivers.
