Suitable for rack-to-rack or top-of-rack connections in data centres and enterprise networks.

## Long description

Passive SFP28 DAC cable CBO SFP28-DAC-0.5M is a 0.5 metre Direct Attach Copper assembly designed for 25Gbps SFP28 ports. It provides a fixed copper connection between compatible switches, routers or network interface cards (NICs) without the need for separate optical transceivers. The cable is intended for short-reach interconnects such as rack-to-rack or top-of-rack links in data centres and enterprise networks, delivering low latency and reduced power consumption compared with active or optical modules.
Advantages
The direct-attach copper design offers predictable electrical performance and minimal signal conversion, reducing latency and energy use. At 0.5 m length the assembly minimises insertion loss and provides a reliable, low-cost connection that is simple to install and maintain. Passive construction eliminates onboard electronics, contributing to lower heat generation and straightforward compatibility with SFP28 ports that support passive DACs.
Suitable for
 Short-reach 25Gbps connections between adjacent racks
 Top-of-rack switching to aggregation switches
 Direct server-to-switch links using SFP28 ports
 Environments prioritising low latency and low power
Key specifications
 Connector type: SFP28 copper direct-attach
 Data rate: up to 25 Gbps per lane
 Length: 0.5 metre
 Cable type: passive twinax copper assembly
 Typical applications: short-reach server and switch interconnects
 Power consumption: passive, no active electronics
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the devices to be linked until the latch clicks into place. Ensure both devices support passive direct-attach copper assemblies and that ports are configured for 25Gbps operation. No external power or transceiver configuration is required. For removal, press the connector latch and withdraw the cable straight out to avoid damaging the port.
Usage recommendations
For reliable performance, use this 0.5 m passive SFP28 DAC in short-reach scenarios only; avoid using it beyond intended rack-to-rack distances. Verify switch and NIC compatibility with passive DACs and consult device documentation for supported firmware or port settings before installation.
