Plug-and-play operation offers simple installation and reduced power compared with optical transceivers.

## Long description

CBO SFP28-DAC-2M-QN-BL is a 2 meter direct-attach twinax copper cable with SFP28 connectors that supports a 25 Gbit/s data rate. It is intended for short-reach, rack-level interconnects between switches, network interface cards (NICs) and servers in data centre environments. The cable provides a low-latency, power-efficient alternative to optical transceivers and is designed for plug-and-play installation without additional configuration.
Advantages
The direct-attach twinax design delivers low latency and consistent signal integrity for 25 Gbit/s links while reducing power consumption compared with active optical solutions. Its fixed 2 m length simplifies rack planning and avoids the need for separate transceivers, lowering overall cost and complexity. SFP28 form-factor connectors ensure compatibility with equipment that supports SFP28 ports and provide a reliable mechanical connection for repeated insertions.
Suitable for (tasks / use cases)
 Short-reach connections between switches within the same rack or adjacent racks
 Direct connection of servers to top-of-rack switches
 NIC-to-switch links for 25 Gbit/s server uplinks
 High-density data centre topologies where low latency and power efficiency are important
Key specifications
 Length: 2 m
 Connector type: SFP28 on both ends
 Peak data rate: 25 Gbit/s
 Cable type: passive twinax copper
 Typical use: short-reach, rack-level interconnect
 Latency: low, suitable for latency-sensitive applications
How to use
Insert each SFP28 connector into the corresponding SFP28 port on your switch, NIC or server until the latch engages. No additional drivers or configuration are required for standard SFP28-compliant equipment; the link should come up automatically when both ends are properly seated and the devices are powered. Ensure that the cable routing avoids sharp bends and mechanical strain near the connector bodies to maintain signal performance and connector longevity.
Usage recommendations
Use this twinax cable for short-distance, high-throughput links inside racks or between adjacent racks. Verify that both devices support SFP28 passive DAC connections and maintain free airflow around the cable to prevent heat accumulation. Replace the cable if there are visible signs of damage or repeated connection issues.
