## Summary description

CBO DAC cable QSFP28 SC282801L5M26 is a 5-meter direct-attach copper (DAC) twinax cable for QSFP28 ports supporting 100Gbps connections. Designed for short-reach interconnects between switches, servers or routers, it provides low-latency, energy-efficient, and cost-effective connectivity in data centers and enterprise racks where optical transceivers are not required.

## Long description

The DAC cable CBO QSFP28 SC282801L5M26 5 m is a 5‑metre direct-attach copper (DAC) twinax cable compatible with QSFP28 ports and engineered for 100Gbps links. It is intended for short-reach connections inside racks and across adjacent racks where fiber transceivers are unnecessary. The cable provides a low-latency, energy-efficient physical connection between switches, servers, and routers, offering a straightforward cabling option for high-density data centre and enterprise network environments.
Advantages
This direct-attach copper cable delivers native 100Gbps throughput with minimal signal propagation delay and low power consumption compared with active optical solutions. The fixed-configuration twinax design reduces deployment complexity and cost for short-distance interconnects. Its QSFP28 form-factor ensures compatibility with equipment that accepts QSFP28 DACs, enabling simple, plug-and-play connectivity without the need for separate transceivers or optical modules.
Suitable for
Short-reach interconnects within server racks and between adjacent racks in data centres
High-density switch-to-switch or switch-to-server connections requiring 100Gbps bandwidth
Environments where low latency and low power consumption are priorities
Cost-sensitive deployments that prefer copper twinax over optical transceivers for short distances
Key specifications
Connector type: QSFP28 to QSFP28 direct-attach twinax copper
Data rate: 100 Gbps
Length: 5 m
Physical medium: passive copper twinax
Typical application: short-reach rack and adjacent-rack interconnects
Latency: low propagation delay suitable for latency-sensitive applications
Power: passive design with lower power consumption compared to optical transceivers
How to use
Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port on the networking devices until the latch engages. Ensure both ends are seated firmly and that devices are powered according to manufacturer guidelines. The cable is intended for direct attachment and requires no separate transceivers or additional configurations in most standard network environments; however, verify link negotiation and port settings on switches or routers if the link does not establish automatically.
Usage recommendations
Use this 5 m DAC cable for short-distance links where cable routing remains inside racks or between adjacent racks. Avoid sharp bends and excessive mechanical stress; maintain the manufacturer’s minimum bend radius for twinax copper. Confirm compatibility with installed QSFP28 ports and check device documentation for any platform-specific requirements before deployment.
