## Summary description

This passive SFP28 DAC cable from CBO (model SFP28-DAC-2M) is a 2 m copper direct-attach cable designed for SFP28 ports supporting 25GbE connectivity. It provides a low-latency, cost-effective short-reach connection between switches, routers and network interface cards. Ideal for rack-to-rack links, server connections and top-of-rack deployments where a reliable, power-efficient link is required.

## Long description

This passive SFP28 DAC cable CBO SFP28-DAC-2M is a 2 m copper direct-attach cable designed for SFP28 ports and 25GbE networks. It provides a short-reach physical connection between compatible switches, routers and network interface cards without active electronics in the link. The cable is intended for low-latency, power-efficient links in rack environments where cost-effectiveness and reliable point-to-point connectivity are required.
Advantages
The passive construction reduces power consumption and heatsink requirements compared with active optical transceivers, while maintaining predictable latency and signal integrity over short distances. Being a direct-attach copper solution, the cable delivers straightforward plug-and-play deployment, minimal configuration and lower acquisition cost relative to fibre transceivers and separate optics. Its fixed 2 m length simplifies planning for rack-to-rack or within-rack connections.
Suitable for
 Top-of-rack switch to server links
 Rack-to-rack interconnects within the same equipment room
 Direct connections between network interface cards and SFP28 ports
 Short-reach 25GbE uplinks and aggregation ports
Key specifications
 Connector type: SFP28 copper direct-attach
 Cable length: 2 metres
 Supported data rate: 25 Gbps per lane (25GbE)
 Cable medium: Twinax copper
 Latency: Low, suitable for short-reach applications
 Power: Passive (no active components in the cable)
 Typical deployment: Short-distance, within-rack or adjacent racks
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the devices to be connected, ensuring the latch engages. No additional configuration is required on most switches and servers; the link will negotiate 25GbE if both ends support the speed. Route the cable to avoid sharp bends and mechanical strain, and verify link status via device LEDs or management interfaces after installation. For hot-plug operations, follow your equipment manufacturer's guidelines.
Usage recommendations
Use this passive SFP28 DAC cable for short, fixed-length connections where low latency and energy efficiency are priorities. Verify port compatibility with SFP28 direct-attach copper cables on both ends before installation and avoid exceeding the recommended bend radius to maintain consistent performance.
