## Summary description

Passive copper DAC cable CBO QSFP28-DAC-1M is a 1 m direct attach cable supporting 100G connectivity with QSFP28 form factor. Designed for short-reach connections between switches, routers and servers, it provides low-latency, energy-efficient transmission without separate transceivers. Ideal for data center patching, top-of-rack links and high-speed interconnects.

## Long description

Passive copper DAC cable CBO QSFP28-DAC-1M is a 1 m direct attach cable that supports 100G connectivity in a QSFP28 form factor. Designed for short-reach connections in data center environments, this cable enables direct electrical links between QSFP28 ports on switches, routers and servers without the need for separate optical transceivers. The single-cable design reduces component count and simplifies rack cabling for top-of-rack and aggregation links.
Advantages
The cable delivers low-latency, energy-efficient transmission over a short distance with predictable electrical performance. As a passive direct attach solution it eliminates the power draw and configuration overhead of active optical modules, and its compact QSFP28 connector saves port space while maintaining 100G throughput. The standardized QSFP28 form factor ensures compatibility with equipment that supports direct-attach copper connections.
Suitable for
Short-reach connections between top-of-rack switches and servers
High-speed interconnects within a rack or between adjacent racks
Data center patching and aggregation links where 100G electrical interfaces are supported
Key specifications
Cable type: passive direct attach copper (DAC)
Connector type: QSFP28 to QSFP28
Length: 1 metre
Data rate: 100 Gbit/s
Use case: short-reach electrical interconnects
Form factor: QSFP28
How to use
Insert each QSFP28 connector into the corresponding 100G QSFP28 port on your switch, router or server until the latch engages. Ensure both ports support passive DAC copper connections and that the device firmware or configuration allows a fixed electrical link. Route the cable to avoid tight bends and mechanical strain; keep the length within the designed 1 m reach to maintain signal integrity. If replacing an existing transceiver-based link, power down equipment or follow hot-swap procedures recommended by the equipment vendor.
Usage recommendations
Use this 1 m passive QSFP28 DAC for short, fixed links inside racks or between adjacent racks where 100G electrical interfaces are supported. Avoid installation near high electromagnetic interference sources and maintain bend radius recommendations to ensure stable performance.
