## Long description

The CBO DAC cable SFP28-DAC-1M is a 1 metre passive copper twinax cable with SFP28 connectors designed for short-range, high-speed connections between SFP28 ports. Intended for use in data centre and rack-to-rack environments, this direct attach copper (DAC) link provides a low-latency physical connection for servers, switches and storage systems. The cable features a compact design that supports straightforward plug-and-play installation without the need for additional transceivers or configuration changes.
Advantages
This passive copper SFP28 cable delivers a cost-effective, low-power solution for 25GbE and similar high-speed interconnects within short distances. Its twinax construction minimises signal degradation over the 1 metre span and provides consistent latency and throughput for time-sensitive applications. The integrated SFP28 connectors ensure compatibility with standard SFP28 ports, reducing component count and simplifying rack-level cabling. The product’s form factor eases cable management in densely populated racks.
Suitable for
Short-range 25GbE server-to-switch connections
Switch-to-switch or switch-to-storage links within the same rack or adjacent racks
Data centre top-of-rack and end-of-row cabling
Low-latency networking for virtualisation and storage traffic
Key specifications
Cable type: passive copper twinax
Connector type: SFP28 on both ends
Length: 1 metre
Bandwidth support: suitable for 25GbE-class links and compatible high-speed protocols
Latency: low, suitable for time-sensitive interconnects
Application environment: data centre and rack-to-rack installations
How to use
Install the CBO DAC cable by inserting each SFP28 connector into corresponding SFP28 ports on the devices to be linked, ensuring connectors are fully seated and latches engage. No external power, transceivers or additional configuration is required for basic connectivity; host devices should automatically detect the physical link if they support passive DAC modules. Observe standard handling precautions: avoid excessive bending or pulling, and route the cable to prevent strain on connectors.
Usage recommendations
For reliable operation, use this passive DAC cable for links up to 1 metre in length and within the same rack or between adjacent racks. Verify device compatibility with passive SFP28 twinax cables in device documentation, and ensure adequate airflow and cable management in dense installations to maintain signal integrity and system cooling.
