## Summary description

CBO DAC cable QSFP28 SC282801L3M26 3 m is a 3‑metre direct attach copper (DAC) assembly designed for QSFP28 ports. It provides a short‑reach, low‑latency connection between switches, routers or servers with QSFP28 interfaces. Suitable for high‑density rack environments, it simplifies cabling, reduces power and eliminates the need for optical transceivers.

## Long description

The DAC cable CBO QSFP28 SC282801L3M26 3 m is a 3-metre direct attach copper assembly engineered for QSFP28 ports. It establishes a short-reach, low-latency electrical link between network devices with QSFP28 interfaces, such as switches, routers and servers. Designed for high-density rack installations, the cable provides a compact, plug-and-play alternative to optical transceivers and fibres, reducing power consumption and simplifying physical layer management.
Advantages
This DAC cable delivers low-latency performance and reliable signal integrity over short distances, making it suitable for latency-sensitive connections. Its fixed copper construction removes the need for separate transceivers and optical modules, lowering both initial hardware costs and ongoing power draw. The assembly’s form factor is optimized for dense port configurations, helping to maintain clean cable routing and minimise space use in racks and patch panels.
Suitable for
 Short-reach interconnects between QSFP28-enabled switches in data centre racks
 Direct server-to-switch or server-to-router links with QSFP28 ports
 High-density networking environments where space and power efficiency matter
 Applications requiring low-latency, high-bandwidth connections within the same rack or adjacent racks
Key specifications
 Connector type: QSFP28 to QSFP28 direct attach
 Cable type: Direct attach copper (DAC)
 Length: 3 metres
 Application: Short-reach, high-speed electrical interconnect
 Performance: Designed for 100Gbps connectivity over QSFP28 interfaces
 Compatibility: Intended for QSFP28 ports on switches, routers and servers
 Installation: Plug-and-play, no external power or transceivers required
How to use
Power down is not required for most hot-pluggable QSFP28 ports; verify vendor documentation for specific equipment. Align the QSFP28 connectors with the device ports and insert until the retention mechanism engages. Ensure both ends are fully seated and that the cable is routed to avoid sharp bends and mechanical strain. Monitor link status through the connected devices to confirm the physical layer is active and performing as expected.
Usage recommendations
Use this DAC cable for short-distance interconnections within the same rack or adjacent racks to achieve low latency and efficient power use. Avoid exceeding the recommended bend radius, keep the cable away from sources of electromagnetic interference, and consult switch or server compatibility lists to ensure full interoperability.
