## Summary description

Direct-attach copper (DAC) cable CBO BlueLAN QSFP28 SC282801L2M30, 2 meters length. Designed for high-speed server, switch and storage interconnects using QSFP28 ports. Passive copper construction provides low-latency, short-reach connectivity for 100Gbps links, simplifying rack-to-rack or within-rack connections while reducing power consumption and cost compared with optical transceivers.

## Long description

The CBO DAC Cable QSFP28 BlueLAN SC282801L2M30 is a 2 m passive direct-attach copper cable engineered for short-reach 100Gbps interconnects. Intended for use with QSFP28 ports, this cable provides a low-latency, high-bandwidth link between servers, switches and storage systems inside a rack or between adjacent racks. Its passive copper construction eliminates the need for optical transceivers, offering a straightforward, cost-effective connectivity option for data center topologies that require reliable, high-speed links over short distances.
Advantages
The cable delivers stable 100Gbps performance with minimal latency and power draw due to its passive design. Its 2-meter length balances flexibility and cable management in dense rack environments. Compatibility with standard QSFP28 interfaces ensures plug-and-play installation without additional drivers or configuration. The copper assembly provides durable physical connection and predictable electrical characteristics for consistent signal integrity in short-reach applications.
Suitable for
Rack-to-rack connections in data center rows
Within-rack server-to-switch or switch-to-switch links
High-throughput storage area network (SAN) paths
Short-reach 100Gbps aggregation and spine-leaf fabrics
Key specifications
Connector type: QSFP28 to QSFP28 compatible
Length: 2 meters
Transmission rate: up to 100 Gbps
Construction: passive direct-attach copper (DAC)
Reach: short-reach, rack-level and adjacent rack connectivity
Latency: low, suitable for latency-sensitive applications
Power: passive design with reduced power consumption compared with active or optical solutions
How to use
Install the cable by inserting QSFP28-compatible ends into the corresponding ports on each device, ensuring connectors are fully seated and latches (if present) engage. Verify link status on connected equipment and check port speed negotiation to confirm operation at 100Gbps. For best signal integrity, route the cable with gentle bends and avoid sharp kinks; maintain proper separation from high-power electrical cabling where possible. No special drivers are required for passive direct-attach copper; device firmware should handle the interface automatically.
Usage recommendations
Use this 2 m passive QSFP28 DAC for short-distance, high-bandwidth interconnects inside racks or between adjacent racks. Choose passive copper when low latency, lower power consumption and lower cost are priorities and when environmental factors (electromagnetic interference, temperature) are within typical data center ranges. Inspect connectors before insertion and replace the cable if physical damage is observed.
