## Summary description

CBO QSFP28-DAC-1M is a 1-meter passive copper DAC cable with QSFP28 connectors supporting 100Gbps links. Designed for short-range high-speed interconnects between network devices such as switches, routers and servers, it offers low-latency, plug-and-play installation and a compact form factor for data center topologies and server racks.

## Long description

CBO QSFP28-DAC-1M is a 1-meter passive copper direct attach cable with QSFP28 connectors engineered to support 100Gbps links. The cable is intended for short-range, high-speed interconnects between network devices such as switches, routers and servers. Its passive design provides low latency and plug-and-play installation while the compact form factor helps optimize space in data center topologies and server racks.
Advantages
The passive copper construction delivers reliable 100Gbps throughput with minimal signal processing, reducing power consumption compared with active optical alternatives. QSFP28 connectors ensure compatibility with devices that accept QSFP28 form-factor transceivers and the 1 m length is suitable for direct connections inside racks or between adjacent racks. The cable’s flexibility and small cross-section simplify cabling management and help maintain airflow in dense installations.
Suitable for
Short-reach connections between switches and aggregation devices within a rack
Direct links from servers to top-of-rack switches
High-performance computing clusters requiring low-latency interconnects
Data centre patching where cost-efficient 100Gbps links are needed
Key specifications
Connector type: QSFP28 to QSFP28
Length: 1 meter
Media: passive copper twinax
Data rate: 100 Gbit/s
Form factor: direct attach cable suitable for QSFP28 ports
Typical use: short-range, in-rack or adjacent rack connections
How to use
Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port on the network devices until it latches. Ensure that both devices are powered down or follow hot‑plug guidelines from the device manufacturer if connecting live. After physical connection, verify link status through device management interfaces and monitor for expected 100Gbps link negotiation. Route the cable to avoid sharp bends and maintain recommended bend radius for copper twinax to prevent performance degradation.
Usage recommendations
Use this passive DAC for reliable, short-distance 100Gbps links inside racks or between adjacent racks. Avoid extended runs beyond the recommended distance for passive copper and ensure ports explicitly support QSFP28 direct attach cables. For longer distances or electrical noise-sensitive environments, consider active or optical alternatives.
