## Long description

CBO BlueLAN QSFP28 SC282801L2M30 is a 2 m Direct Attach Copper (DAC) cable engineered for QSFP28 ports. The cable provides a fixed, low-latency copper connection for high-speed networking equipment, enabling short-reach links between switches, routers and servers that support QSFP28 interfaces. Designed as a passive copper interconnect, it eliminates the need for separate optical transceivers and offers plug-and-play installation for rack-to-rack and top-of-rack connections in data centre environments.
Advantages
This 2 m DAC cable delivers deterministic, low-latency performance and maintains signal integrity over short distances typical of data centre and server-room deployments. As a direct-attach solution it reduces component count and power consumption compared with optical modules and active optical cables. The cable’s QSFP28 form-factor compatibility ensures straightforward integration with compatible ports and simple hot-plug operation without additional configuration.
Suitable for
 Short-reach data centre interconnects between racks
 Switch-to-switch connections within the same equipment row
 Server-to-switch uplinks where QSFP28 ports are available
 High-density networking installations requiring compact, low-latency links
Key specifications
 Connector type: QSFP28 direct-attach copper
 Cable length: 2 m
 Cable medium: copper twinax (direct attach)
 Form factor: QSFP28 compatible plug
 Typical use: short-reach, rack-to-rack and intra-rack links
 Latency: low, suitable for high-throughput, low-latency applications
How to use
Install the DAC cable by inserting each QSFP28 plug into the corresponding QSFP28 ports on the two devices until the connector latches. No additional drivers or transceivers are required for standard QSFP28-enabled equipment. Verify link status through the device LEDs or management interface and confirm the negotiated speed and lane configuration. For reliable operation, avoid excessive bending of the cable and ensure the path between devices is free from tight bends or mechanical strain.
Usage recommendations
Use this 2 m DAC cable for short, high-bandwidth links inside racks or between adjacent racks. Maintain bend radii recommended by the manufacturer, avoid routing near high-heat equipment, and verify compatibility with your QSFP28 ports and switch firmware to ensure optimal performance.
