## Long description

Direct Attach Copper (DAC) cable CBO QSFP28-DAC-2M is a 2 m passive twinax assembly designed for QSFP28 ports and compatible with Radware QSFP28 equipment. The cable provides a short-range, high-bandwidth connection between QSFP28 networking devices, enabling low-latency links and simplified rack cabling in data center environments. Its fixed 2 metre length and QSFP28 terminations make it suitable for top-of-rack, middle-of-row and short in-rack connections where fiber transceivers are not required.
Advantages
The CBO QSFP28-DAC-2M offers low insertion loss and predictable electrical performance for 100 Gigabit Ethernet and other QSFP28 applications. As a passive twinax assembly it consumes no additional power, eliminates the need for separate transceivers, and reduces total cost of ownership for short-distance links. The direct-attach design simplifies installation and cable management while delivering stable throughput and reduced latency compared with longer optical links in comparable setups.
Suitable for
 Short-range 100 GbE connections between switches and routers
 Server to switch links in data center racks
 Interconnects in network closets and aggregation layers
 High-density rack deployments where space and cable management matter
Key specifications
 Connector type: QSFP28 to QSFP28 passive twinax
 Length: 2 metres
 Performance: suitable for 100 Gigabit Ethernet and QSFP28 interfaces

How to use
Install the CBO QSFP28-DAC-2M by inserting each QSFP28 connector into the corresponding QSFP28 port on your devices until the latch engages. Ensure both devices are powered and configured for the intended 100 GbE link prior to traffic testing. Avoid excessive bending of the twinax cable near the connector ends and maintain recommended bend radii to preserve signal integrity. For equipment firmware or compatibility restrictions, confirm support for passive DAC cables in the device documentation.
Usage recommendations
Use this 2 m passive DAC cable for short intra-rack and adjacent-rack connections where 100 GbE performance, low latency, and straightforward cable management are required. Keep the cable free from crush and sharp bends, and verify device compatibility with Radware QSFP28 ports before deployment.
