## Summary description

CBO SFP28-DAC-2M is a 2‑metre direct-attach copper (DAC) cable for SFP28 ports supporting 25Gbps links. Designed as a low-latency, low-power connection between switches, servers or NICs, it provides a fixed copper connection compatible with Zyxel SFP28 interfaces. Ideal for short‑reach rack connections, it simplifies cabling and reduces latency and power compared with optical modules.

## Long description

CBO SFP28-DAC-2M is a 2-metre direct-attach copper (DAC) cable engineered for SFP28 ports and 25Gbps links. It provides a fixed copper connection between compatible network devices such as switches, servers and NICs, offering a low-latency and low-power alternative to optical transceivers for short-reach rack interconnects. The cable is compatible with Zyxel SFP28 interfaces and is intended for short-distance connections inside racks and between adjacent equipment where a reliable, cost-effective copper link is required.
Advantages
The direct-attach copper design delivers minimal link latency and reduced power consumption compared with active optical solutions, making it suitable for high-density, performance-sensitive environments. As a passive fixed-format cable, it eliminates the need for separate transceivers and fiber patching for short links, simplifying installation and ongoing maintenance. Its 2 metre length balances reach and signal integrity for typical rack-to-rack or server-to-switch connections.
Suitable for
 Short-reach connections between switches and servers inside racks
 High-density top-of-rack and spine-leaf deployments
 Direct attachment to SFP28 ports on NICs and line cards
 Environments prioritising low latency and low power consumption
Key specifications
 Form factor: SFP28 direct-attach copper
 Nominal length: 2 metres
 Data rate: 25 Gbps per lane
 Cable type: Twinax copper assembly (passive)
 Typical application: Short-reach rack and chassis interconnects
How to use
Install the DAC cable by inserting each SFP28 connector into the corresponding SFP28 port on the network devices until the retention latch engages. Ensure both ports are powered and configured for 25Gbps operation. No additional optics or transceivers are required. Verify link status and port statistics on connected devices to confirm a stable 25Gbps connection. For hot-plug operations, follow the equipment manufacturer's guidance on inserting and removing connectors to avoid port damage.
Usage recommendations
Use this 2 m direct-attach cable for short, fixed connections within racks or between adjacent racks. Avoid sharp bends and maintain manufacturer-recommended bend radii. For longer distances or runs requiring flexible reconfiguration, consider appropriate optical transceivers and fiber cabling instead.
