## Summary description

Direct Attach Copper (DAC) cable CBO QSFP28-DAC-1M is a 1-meter passive copper interconnect supporting 100G data rates via QSFP28 interfaces. Designed for short-reach connections between switches, routers, and servers in data centers and high-performance racks. Provides low-latency, power-efficient links and plug-and-play compatibility with QSFP28 ports for reliable 100G connectivity.

## Long description

Direct Attach Copper (DAC) cable CBO QSFP28-DAC-1M is a 1-meter passive copper interconnect engineered for 100G connectivity using QSFP28 interfaces. It offers a straightforward, low-latency link for short-reach connections in data centers and high-density network racks, enabling direct connections between switches, routers and servers without the need for optical transceivers. The cable is designed for plug-and-play operation with QSFP28 ports and prioritizes energy efficiency and stable performance for high-throughput environments.
Advantages
This 1m passive copper DAC provides reliable 100G transmission with minimal latency and reduced power consumption compared with active or optical alternatives. Its compact, single-cable form factor simplifies rack cabling and reduces space usage while delivering consistent signal integrity over short distances. The product is compatible with standard QSFP28 interfaces, ensuring straightforward installation and interoperability in many common data center setups.
Suitable for
Short-reach server-to-switch and switch-to-switch connections in data centers
High-density rack deployments and top-of-rack switching
Low-latency environments such as high-performance computing clusters
Cost- and power-sensitive network infrastructure where optical transceivers are unnecessary
Key specifications
Interface: QSFP28 to QSFP28
Length: 1 meter
Transmission: Passive copper
Data rate: 100 Gigabit Ethernet
Latency: low, suitable for short-reach applications
Form factor: twinaxial cable with QSFP28 connectors
How to use
Connect each QSFP28 connector to the corresponding QSFP28 port on your network devices, ensuring the latch engages and the plug is seated securely. The cable is intended for short-reach connections within racks or between adjacent racks; avoid tight bends and excessive cable strain to maintain signal integrity. No additional configuration is typically required — the link should negotiate automatically at 100G if both endpoints support the standard.
Usage recommendations
Install the cable in clean equipment bays and route it to prevent sharp bends; maintain recommended bend radius for twinax cables. Verify QSFP28 port compatibility and firmware support on connected devices if you encounter link issues. For runs longer than 1 meter or for environments requiring optical isolation, consider appropriate optical transceivers or active DAC alternatives.
