## Summary description

CBO BlueLAN QSFP28 DAC cable (model SC282801L3M26) is a 3-meter Direct Attach Copper assembly for QSFP28 interfaces. Designed for short-range, high-speed connections between switches, servers and storage, it provides a cost-effective, low-latency link compatible with QSFP28 ports. Ideal for data center top-of-rack and adjacent-rack connections where a fixed copper twinax solution is preferred.

## Long description

CBO BlueLAN QSFP28 DAC Cable SC282801L3M26 is a 3-meter Direct Attach Copper (DAC) assembly designed for QSFP28 interfaces. It provides a fixed twinax copper connection for short-range, high-speed links between network switches, servers and storage devices. The cable supports low-latency data transmission and is intended for top-of-rack and adjacent-rack connections in data center environments where a cost-effective, high-throughput copper solution is required.
Advantages
The Direct Attach Copper design ensures predictable latency and reliable signal integrity over short distances without the need for optical transceivers. The 3 m length offers flexibility for common rack and cabinet layouts while keeping signal loss minimal. Built to interface with QSFP28 ports, the cable simplifies deployment by enabling a plug-and-play connection that reduces hardware and power costs compared with active or optical alternatives.
Suitable for
 Top-of-rack connections between switches and servers
 Adjacent-rack links inside the same aisle or cabinet
 High-throughput, low-latency interconnects in data centers
 Short-range links in storage area networks (SAN) and HPC clusters
Key specifications
 Interface type: QSFP28 compatible twinax copper
 Cable type: Direct Attach Copper (twinax)
 Length: 3 meters
 Designed use: short-range, high-speed data center interconnects
 Latency profile: low-latency physical connection suitable for 100G links
 Form factor: QSFP28 connector ends for direct port mating
How to use
Insert each QSFP28 connector end into the corresponding QSFP28 ports on the devices to be connected, ensuring secure seating and latch engagement. No separate transceivers or additional power are required; the cable functions as a fixed copper link. Verify device compatibility with QSFP28 passive DAC connections and confirm firmware or port settings if necessary to enable the expected link speed and lane configuration. For initial deployment, test the link status and throughput using standard network diagnostics on connected equipment.
Usage recommendations
Use this 3 m DAC cable for short, direct connections inside racks or between adjacent racks. Avoid sharp bends, kinks or excessive strain on the twinax cable, and maintain recommended bend radius to preserve signal integrity. Keep connectors clean and protect unused ports with dust caps. For distances beyond short-range top-of-rack or adjacent-rack links, consider active copper or optical fiber alternatives.
