Ideal for short-reach interconnects in racks and data centers, offering plug-and-play simplicity and reduced power consumption compared to active modules.

## Long description

Passive copper DAC cable CBO SFP28-DAC-2M is a 2 meter direct-attach cable designed for SFP28-to-SFP28 connections. It provides a low-latency, low-power physical link suitable for 25GbE or compatible SFP28 ports in switches, servers and storage systems. The cable is intended for short-reach interconnects within rack environments and data center topologies where cost-efficiency and plug-and-play installation are required.
Advantages
This passive SFP28 DAC offers reduced power consumption compared with active optical modules and eliminates the need for separate transceivers by integrating the copper twinax assembly. The 2 m length balances flexibility and signal integrity for typical rack-to-rack or device-to-device distances. Installation is straightforward with hot-pluggable SFP28 connectors and compatibility with standard SFP28 cages on network equipment.
Suitable for
25 Gigabit Ethernet uplinks and server-to-switch links
Short-reach interconnects inside racks and between adjacent racks
High-density top-of-rack or leaf-spine network deployments
Server and storage connectivity in data center and virtualized environments
Key specifications
Cable type: passive twinax copper direct-attach cable
Connector type: SFP28 to SFP28
Nominal length: 2 m
Supported data rate: suitable for 25GbE and SFP28-compatible rates
Latency: low, inherent to passive copper interconnects
Power consumption: minimal compared with active optics
Form factor: fixed, molded connectors for hot-pluggable use
How to use
Insert each SFP28 connector into the SFP28 port of the two devices to be connected, ensuring the latch clicks into place. The cable supports plug-and-play operation with no additional configuration required on compliant network equipment. Verify link status and speed on connected devices' management interfaces and ensure both ports are enabled and configured for the intended data rate. For reliable operation, avoid sharp bends and keep the cable secured within the rack to prevent strain on the connectors.
Usage recommendations
Use this 2 m passive DAC for connections within a single rack or between adjacent racks; for longer distances or where electromagnetic isolation is required, consider optical transceivers and fiber cabling. Maintain proper bend radius, avoid kinking, and inspect connector contacts for debris before insertion.
