## Long description

The CBO DAC cable SFP28-DAC-2M is a 2-meter passive copper twinax assembly designed for direct attachment between SFP28 ports. Built for short-range 25GbE or compatible SFP28 connections, this fixed cable provides a low-latency, power-efficient alternative to optical transceivers and patch cables. It is intended for reliable rack-to-rack, switch-to-server or switch-to-switch links in data center and enterprise network topologies where cost and energy efficiency are important.
Advantages
This passive twinax cable offers reduced latency and lower power consumption compared with active optical solutions, while eliminating the need for separate transceivers. The fixed 2 m length simplifies cable management and ensures consistent signal integrity for short-range interconnects. The integrated SFP28 connectors are designed to fit standard SFP28 ports and provide a plug-and-play connection without additional configuration.
Suitable for
 Short-range 25GbE links between switches and servers
 Top-of-rack to aggregation switch connections
 Direct attach links within data center racks
 Environments prioritizing low power and low latency
Key specifications
 Connector type: SFP28 compatible plug on both ends
 Length: 2 meters fixed twinax cable
 Cable medium: Passive copper (twinax)
 Supported interface: 25 Gigabit Ethernet and compatible SFP28 links
 Latency: Low latency suitable for short-range interconnects
 Power: Passive design requires no external power
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the network devices until the latch engages. Ensure both ends are fully seated and that the connected devices are powered and configured for the same link speed and duplex settings. No additional transceivers or cables are required; the cable functions as a direct attach link for supported SFP28 ports. For optimal performance, avoid sharp bends and maintain proper cable routing to prevent kinking.
Usage recommendations
Use this 2 m passive DAC cable for short-distance direct connections inside racks or between adjacent racks. Verify device compatibility with passive SFP28 direct attach copper before deployment and route the cable to minimize mechanical stress and electromagnetic interference.
