## Summary description

CBO DAC cable QSFP28 BlueLAN SC282801L1M30, 1 m, is a direct attach copper (DAC) assembly for 100Gbps QSFP28 interfaces. Designed for short-reach server-to-switch or switch-to-switch connections, it provides low-latency, low-power, and reliable 100GigE links without transceivers. Ideal for data centers and high-density racks where cost-effective, high-throughput connectivity is required.

## Long description

CBO DAC cable QSFP28 BlueLAN SC282801L1M30 1 m is a direct attach copper assembly engineered for 100Gbps QSFP28 interfaces. It provides a ready-made twinax copper connection for short-reach links between servers, switches or other QSFP28 ports. By integrating the cable and connectors into a single pre-terminated unit, this 1 metre DAC delivers low-latency, low-power connectivity suited to high-density rack environments and data centre topologies where simple, cost-effective 100GigE links are required.
Advantages
This BlueLAN DAC cable reduces system complexity by eliminating the need for separate optical transceivers and fibre patching for short links. Its direct attach copper design keeps power consumption and latency minimal while maintaining full 100Gbps throughput. The compact 1 m length helps manage cable routing and supports high port density in switch and server deployments. The cable is compatible with standard QSFP28 ports and is intended for reliable, repeatable short-range connectivity in dense networking setups.
Suitable for
Short-reach server-to-switch connections within the same rack or adjacent racks
Switch-to-switch links in top-of-rack or leaf-spine architectures
High-density data centre installations requiring low-latency 100Gbps links
Environments where power efficiency and minimal heat generation are important
Key specifications
Interface: QSFP28 to QSFP28 direct attach copper
Rated data rate: 100 Gbps
Cable type: twinax copper, pre-terminated
Length: 1 metre
Designed for short-reach links within racks or between adjacent racks
Low latency and low power consumption compared with optical transceivers
How to use
Insert each QSFP28 connector into the corresponding QSFP28 port on the devices to be linked, ensuring the latch engages. Use the 1 m DAC cable for connections within the same rack or between neighbouring racks where short-reach copper is suitable. Ensure devices are powered down or ports are configured to accept direct-attach copper modules if required by the equipment vendor. Verify link status through network management tools or device LEDs after connection.
Usage recommendations
For reliable operation, avoid tight bends and excessive pulling on the twinax cable and maintain proper airflow around equipment. Confirm compatibility with your switch or server vendor for QSFP28 direct attach copper assemblies and follow vendor guidance for insertion and removal procedures to protect ports and connectors.
