## Summary description

CBO QSFP28-DAC-1M is a 1-meter passive copper Direct Attach Cable (DAC) with QSFP28 connectors supporting 100Gbps links. Designed for short-reach interconnects between switches, routers, and network adapters, it provides low-latency, power-efficient connectivity in data centers and server racks. Ideal for high-speed aggregation, top-of-rack or spine connections where a short, reliable 100Gbps link is required.

## Long description

CBO QSFP28-DAC-1M is a 1‑meter passive copper Direct Attach Cable (DAC) with QSFP28 connectors that supports 100Gbps links. It is designed for short‑reach interconnects between switches, routers and network adapters, providing low latency and low power consumption for data center and server rack environments. The compact, single‑cable design simplifies high‑speed aggregation and top‑of‑rack or spine connections where a reliable 100Gbps link over a short distance is required.
Advantages
The passive copper construction delivers consistent 100Gbps throughput with minimal signal conditioning, reducing power draw compared with active optical modules. A fixed 1 m length simplifies cabling planning and minimizes footprint in dense racks. QSFP28 connectors ensure compatibility with 100Gbps QSFP28 ports and support hot‑plug installation for fast maintenance. The cable's robust shielding and connector design provide stable electrical performance and resistance to electromagnetic interference in typical data center deployments.
Suitable for
 Short‑reach connections between top‑of‑rack switches and aggregation or spine switches
 Direct attach links between servers and network adapters supporting QSFP28 100Gbps
 High‑density server racks where low latency and reduced power consumption are needed
 Temporary or permanent high‑speed links in data center patching and lab environments
Key specifications
 Interface: QSFP28 to QSFP28
 Supported data rate: 100 Gbps
 Cable type: Passive copper Direct Attach Cable (DAC)
 Length: 1 meter
 Form factor: Quad Small Form‑factor Pluggable 28 (QSFP28)
 Typical use case: Short‑reach interconnects within racks and between adjacent racks
How to use
Ensure both devices have compatible QSFP28 ports and support passive copper DACs at 100Gbps. With equipment powered on or off (follow vendor guidance), align the QSFP28 connector latch with the port and insert until the connector clicks into place. Confirm link status via device LEDs or management interface and verify negotiated link speed. To remove, release the latch and pull the connector straight out to avoid damaging the port. Maintain gentle bends and avoid kinking the cable to preserve signal integrity.
Usage recommendations
Install the cable in rack environments with adequate airflow and avoid routing near large sources of electromagnetic interference. Use the 1 m length for direct, short‑reach links; for longer spans select an appropriate active copper or optical solution. Periodically inspect connectors for dust or damage and clean with manufacturer‑approved methods if necessary.
