## Summary description

CBO BlueLAN QSFP28 DAC cable SC282801L1M30 is a 1-meter Direct Attach Copper (DAC) assembly with QSFP28 connectors. Designed for short-reach high-speed interconnects, it supports QSFP28-compatible network equipment for server, switch, and storage interconnections. Suitable for rack-to-rack connections, it offers a simple, low-latency copper link without separate transceivers.

## Long description

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.
Usage 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.
