## Summary description

CBO QSFP28-DAC-3M is a 3-meter direct-attach copper (DAC) cable compatible with IBM QSFP28 ports. It provides a cost-effective, low-latency connection for high-speed network links, server-to-switch or switch-to-switch interconnects in datacenters and racks. Designed for short-reach interconnects, it requires no transceivers and simplifies installation while preserving QSFP28 interface compatibility.

## Long description

CBO QSFP28-DAC-3M is a 3-meter direct-attach copper (DAC) cable compatible with IBM QSFP28 ports. It delivers a low-latency, high-bandwidth connection for short-reach links in data centers and rack environments without requiring separate transceiver modules. The cable preserves the QSFP28 electrical interface and supports straightforward server-to-switch and switch-to-switch interconnects while reducing power consumption and hardware complexity.
Advantages
The DAC cable offers a cost-effective alternative to optical modules for short-distance connections, combining plug-and-play installation with reduced heat and power draw. Its fixed 3 m length minimizes signal loss over short reaches and eliminates the need to manage separate transceivers. Compatibility with QSFP28 ports ensures interoperability with equipment that supports the QSFP28 electrical form factor, allowing reliable 100Gbps-class links when used inside supported systems.
Suitable for
Short-reach 100GbE links inside racks and between adjacent racks
Server-to-switch interconnects in data center topologies
Switch-to-switch uplinks in aggregation and spine-leaf architectures
Environments where power efficiency and low latency are priorities
Key specifications
Connector type: QSFP28 compatible direct-attach copper
Cable length: 3 meters
Media: copper twinax for short-reach interconnects
Optimized for low latency and reduced power consumption compared to optical transceivers
Designed for use with QSFP28 electrical interfaces at 100Gbps-class links
How to use
Insert each QSFP28 connector into the corresponding QSFP28 port on the devices to be interconnected, ensuring the latch engages and the connectors are fully seated. No additional transceiver modules, fiber cabling, or external power are required. Verify link status through the equipment management interface and confirm that both endpoints are configured for the intended speed and link settings. For safe removal, follow the host device’s recommended hot‑swap or power‑down procedures if applicable, then depress the latch and withdraw the connector.
Usage recommendations
Use this 3 m DAC cable for short-distance connections within and between adjacent racks. Avoid bending the cable beyond its minimum bend radius, route it to prevent mechanical strain on the connectors, and operate within the equipment’s specified temperature range. Confirm compatibility with your switches and servers’ QSFP28 ports and firmware to ensure proper negotiation of link speed and features.
