## Summary description

Passive SFP28 Direct Attach Copper (DAC) cable by CBO, model SFP28-DAC-5M-SO-BL, 5 meters long with male-to-male SFP28 connectors and 25 Gbit/s data rate. Designed for short-reach high-speed connections between switches, routers or network interface cards, it provides low-latency, energy-efficient connectivity and simple plug-and-play installation in data centers and server racks.

## Long description

CBO SFP28 Direct Attach Copper Cable SFP28-DAC-5M-SO-BL is a 5 metre passive twinax cable with male-to-male SFP28 connectors and a 25 Gbit/s maximum data rate. It is intended for short-reach, high-bandwidth links in data centre and server rack environments where low latency and energy-efficient operation are required. The cable supports direct connections between SFP28 ports on switches, routers and network interface cards without the need for separate optical transceivers.
Advantages
This SFP28 DAC provides a cost-effective, low-power connection for 25 Gigabit Ethernet links over short distances. Its passive twinax construction reduces latency and power consumption compared with active optical or transceiver-based solutions, while the integrated male-to-male SFP28 plugs enable straightforward hot-plug installation. The 5 m length offers flexible routing within racks and across adjacent rack aisles, maintaining signal integrity for typical data centre layouts.
Suitable for
 Short-reach 25 Gigabit Ethernet links between switches
 Direct connections from servers to top-of-rack switches
 Interconnects between routers and network interface cards (NICs)
 High-density spine-and-leaf data centre deployments
 Environments prioritising low latency and reduced power consumption
Key specifications
 Connector type: SFP28 male-to-male
 Length: 5 metres
 Data rate: up to 25 Gbit/s
 Media: passive copper twinax
 Latency: low, suitable for short-reach high-speed links
 Compatibility: designed for SFP28 ports supporting direct-attach copper
 Installation: plug-and-play, hot-pluggable
How to use
Insert each male SFP28 connector into the corresponding SFP28 port on your network devices until the retention latch engages. Ensure both devices are powered and configured to use a 25 Gigabit Ethernet link; most modern switches and NICs will auto-negotiate the connection when a compatible passive DAC is attached. Route the cable to avoid sharp bends and heavy compression; maintain bend radius recommendations from your hardware vendor to preserve signal integrity.
Usage recommendations
Use this passive 5 m SFP28 DAC for intra-rack or adjacent-rack connections where the distance does not exceed 5 metres. Verify device compatibility with SFP28 direct-attach copper cables before deployment and keep the cable away from sources of strong electromagnetic interference. For longer runs or different physical layouts consider active DACs or optical transceivers with fibre cabling.
