## Summary description

Passive Direct Attach Copper (DAC) cable by CBO, model QSFP28-DAC-1M, 1 meter length designed for QSFP28 interfaces. Provides a short-range, low-latency electrical connection between compatible network devices such as switches and routers. Suitable for high-speed 100Gbps links where a fixed, cost-effective copper interconnect is required. Plug-and-play operation and compact form factor simplify rack deployments.

## Long description

The BlueOptics DAC cable QSFP28-DAC-1M is a 1 metre passive direct attach copper (DAC) assembly designed for QSFP28 ports. It provides a short-range, low-latency electrical connection between compatible network devices, supporting 100Gbps links for switch-to-switch, switch-to-router or server-to-switch interconnects. The cable is a fixed form-factor solution that simplifies rack deployments and eliminates the need for separate transceivers where short-distance, cost-effective connections are acceptable.
Advantages
This passive QSFP28 DAC cable offers low latency and predictable performance due to its direct copper connection and absence of active electronics. The compact, integrated design reduces space requirements in dense rack environments and supports plug-and-play installation without additional configuration. As a passive solution it is energy-efficient and typically more cost-effective than optical transceivers and fiber assemblies for short runs.
Suitable for
 Short-range 100Gbps connections between switches and routers within the same rack or adjacent racks
 Server-to-switch uplinks in data centre and enterprise network racks
 High-performance network fabrics where fixed, low-latency links are required
Key specifications
 Connector type: QSFP28 to QSFP28 passive copper
 Cable length: 1 metre
 Data rate: up to 100 Gbps
 Topology: direct attach copper (fixed assembly)
 Latency: low, suitable for latency-sensitive links
 Power: passive (no external power or active components)
 Form factor: compact QSFP28 twinax design for dense rack deployments
How to use
Insert one QSFP28 connector end into the QSFP28 port of the first device and the other end into the QSFP28 port of the second device. Ensure both ports support QSFP28 passive DAC connections and that devices are powered off or that hot-swap procedures recommended by the equipment vendor are followed. After insertion, devices typically recognise the cable automatically and establish a 100Gbps link according to the device network configuration.
Usage recommendations
Use this 1 m passive DAC cable for short, direct connections inside racks or between adjacent racks to minimise latency and cost. Avoid tight bends and mechanical stress at the connector ends, maintain proper airflow around equipment, and verify device compatibility with QSFP28 passive twinax cables before deployment.
