## Summary description

CBO SFP28-DAC-2M is a 2 meter passive SFP28 direct attach (DAC) twinax cable for 25Gbps links. Designed for short-reach server, switch and router interconnects, it provides a low-latency, cost-effective alternative to optical transceivers. Compatible with SFP28 ports supporting passive DACs, it simplifies cabling in data centers and rack-to-rack connections.

## Long description

The SFP28 Direct Attach Cable CBO SFP28-DAC-2M is a 2 metre passive twinax cable engineered for 25Gbps connections between SFP28 ports. Intended for short-reach interconnects in racks and data centres, this cable provides a direct electrical connection that reduces latency and simplifies physical layer setup compared with optical transceivers. It is suitable for point-to-point links between servers, switches and routers where SFP28 passive DACs are supported.
Advantages
This passive SFP28 twinax cable delivers low latency and consistent signal integrity for 25Gbps links while requiring no additional power or optical modules. The fixed 2 m length offers predictable cable management in rack and top-of-rack deployments. Passive construction keeps cost and energy consumption lower than active or optical alternatives, and the direct-attach form factor reduces the number of components needed for short-distance connections.
Suitable for
Short-reach server-to-switch and switch-to-switch connections in data centres
Top-of-rack and rack-to-rack 25GbE interconnects
High-density networking environments where low latency is required
Key specifications
Interface type: SFP28 direct attach twinax
Data rate: 25 Gbps per channel
Length: 2 metres
Construction: Passive twinax copper cable
Typical use: Short-reach electrical interconnects for networking equipment
How to use
Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on your network devices until the connector latches. Ensure both devices support passive SFP28 DAC modules and that ports are powered down or follow hot-swap guidance from the equipment vendor when connecting. After physical installation, verify link status and speed through your device management interface and adjust interface settings as required for 25GbE operation.
Usage recommendations
For reliable performance, avoid sharp bends and excessive tensile stress on the cable; maintain minimum bend radius specified by the vendor. Use this 2 m passive DAC for short interconnects inside racks or between adjacent racks; for longer runs or when optical isolation is needed, consider optical transceivers and fibre cabling.
