CBO DAC Cable BlueLAN QSFP28 SC282801L1M30 1M – Direct Attach Copper, QSFP28, 1 m

CBO BlueLAN QSFP28 SC282801L1M30 1M is a Direct Attach Copper (DAC) cable with QSFP28 connectors and a 1 meter length, designed for short-reach, high-bandwidth interconnects in data center environments. The cable provides a direct copper link between QSFP28-compatible network devices such as switches, routers, servers and storage systems, delivering a low-latency physical connection without the need for separate optical transceivers. Its single-meter length makes it suitable for rack-to-rack and intra-rack connections where space and signal integrity are priorities.

Advantages

The DAC assembly offers low power consumption and minimal latency compared with optical modules because the electrical connection eliminates the need for transceivers. Its factory-terminated QSFP28 connectors ensure consistent signal performance and interoperability with equipment that supports QSFP28 interfaces. The fixed 1 m length reduces cabling clutter and simplifies routing in dense rack configurations while maintaining high data throughput for short-distance links.

Suitable for

• Rack-to-rack high-speed connections within the same row
• Intra-rack server-to-switch interconnects
• Switch-to-storage links in data center topologies
• Short-reach aggregation and leaf-spine fabrics

Key specifications

• Connector type: QSFP28 on both ends
• Cable type: Direct Attach Copper (DAC)
• Length: 1 meter
• Intended reach: short-reach, data center interconnects
• Typical use: 100 Gb/s class QSFP28 links for server, switch, and storage equipment

How to use

Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port on network devices until the connector latch engages. Ensure both ends are compatible with the equipment and powered down or in maintenance mode if recommended by the device manufacturer to avoid hot-plug issues. Route the cable to avoid sharp bends and mechanical strain; a 1 m length is intended for close-proximity connections within racks or between adjacent racks.

Recommendations

Confirm QSFP28 port compatibility and firmware support on both devices before deployment. Maintain bend radius and avoid excessive twisting; store and handle the cable in a clean environment to prevent connector contamination. For longer distances or optical isolation requirements, consider optical transceiver-based solutions instead of a DAC cable.
