Designed for short-reach 25GbE connections between switches, NICs and servers, it provides a fixed, low-latency link without separate transceivers. The passive design offers power efficiency and simple plug-and-play deployment in data center top-of-rack and server-rack environments.

## Long description

CBO DAC cable SFP28-DAC-5M is a 5-meter passive copper direct attach cable that connects SFP28 ports for short-reach 25GbE links. It provides a fixed electrical connection between compatible switches, network interface cards (NICs) and servers without requiring separate optical transceivers. The cable is intended for data centre top-of-rack and server-rack installations where a cost-effective, low-latency and power-efficient interconnect is required.
Advantages
The passive design reduces power consumption by eliminating active optics and transceivers, while plug-and-play compatibility simplifies installation and reduces configuration time. The fixed copper assembly delivers consistently low latency and predictable performance for short-distance 25GbE connections. With a 5 m length, the cable supports typical rack-to-rack and switch-to-server layouts without extra modules or fibre patching.
Suitable for
Short-reach 25GbE links between top-of-rack switches and aggregation switches
Direct connections between servers and NICs supporting SFP28
Interconnects inside server racks and adjacent racks within data centres
Environments prioritising low latency and reduced power usage
Key specifications
Interface: SFP28 to SFP28 electrical direct attach
Data rate: 25 Gigabit Ethernet
Length: 5 metres
Cable type: Passive copper twinax
Latency: low fixed-latency electrical link
Deployment: designed for short-reach, within-rack and adjacent-rack connections
How to use
Insert each SFP28 connector into the corresponding SFP28 port on your switch, server or NIC until the latch engages. Ensure both ends are fully seated and that the connected devices are powered and configured to use 25GbE links. No additional transceivers, power sources or media converters are required. Verify link status through device LEDs or management interfaces and monitor performance using standard network tools.
Usage recommendations
Use this passive DAC cable for short-distance connectivity within racks or between adjacent racks. Avoid routing the cable near high electromagnetic interference sources and ensure bend radius recommendations are followed to prevent mechanical stress. Check device compatibility lists for SFP28 passive direct attach support before deployment.
