Suitable for data center topologies, server interconnects and high‑speed networking where a reliable, cost‑effective short‑distance link is required.

## Long description

CBO DAC cable QSFP28 SC282801L2M30 2 m — direct attach copper for QSFP28 ports is a 2‑metre direct attach copper (DAC) assembly engineered for short‑reach high‑speed connections between devices with QSFP28 interfaces. The cable provides a fixed electrical interconnect that eliminates the need for separate optical transceivers, offering a deterministic low‑latency link suitable for data center topologies, server-to-switch connections and point-to-point links inside racks or across adjacent racks.
Advantages
The DAC cable delivers low latency and high signal integrity for short-distance 100 Gigabit connections while keeping power consumption and heat generation minimal compared with active optical solutions. As a direct attach copper assembly, it provides a compact, plug-and-play connection that simplifies installation and reduces component count. The integrated QSFP28 connectors are designed for compatibility with standard QSFP28 ports and for reliable electrical performance in typical data center environments.
Suitable for
Short‑reach 100 Gigabit Ethernet connections between switches and routers
Server to top-of-rack or leaf switch interconnects
High‑performance computing cluster node links
Patch and cross‑connect scenarios within data center cabinets
Key specifications
Connector type: QSFP28 direct attach copper (fixed assembly)
Length: 2 m
Supported data rate: 100 Gbps (QSFP28 electrical specification)
Transmission medium: passive copper cable optimized for short‑reach
Latency: low, fixed electrical link suitable for time‑sensitive applications
Power consumption: minimal compared with active optical alternatives
How to use
Insert each QSFP28 connector into the corresponding QSFP28 port on the devices to be linked, ensuring proper orientation and full seating until the connector latch engages. No external power or separate transceivers are required; the cable establishes the electrical connection immediately after mechanical insertion and host negotiation. For removal, depress the latch mechanism and pull the connector straight out to avoid stress on the cable and port.
Usage recommendations
Use the DAC cable for short, direct connections inside racks or between adjacent racks where a cost‑effective, low‑latency 100 Gbps link is required. Verify QSFP28 port compatibility in the connected devices and ensure rack routing avoids sharp bends or tight strain on the cable; maintain the minimum bend radius specified by the equipment vendor to preserve signal integrity.
