SFP28 DAC cable CBO SFP28-DAC-5M-NG-BL — 5 m, male-to-male, 25 Gbit/s

Direct Attach Copper (DAC) SFP28 cable CBO SFP28-DAC-5M-NG-BL is a 5 m, male-to-male high-speed interconnect supporting 25 Gbit/s. Designed for short-range links between servers, switches and storage in data centres and rack environments, this copper twinax assembly provides low latency and reduced power consumption compared with optical transceivers. The cable is intended for use with SFP28-compliant ports to enable reliable 25GbE or compatible connectivity over a single, pre-terminated cable.

Advantages

The cable delivers native 25 Gbit/s performance with minimal insertion loss and consistent signal integrity across its 5 m length. As a passive copper direct attach solution it reduces the need for separate transceivers and optical modules, lowering both hardware and operational power costs. Its male-to-male SFP28 connectors ensure straightforward plug-and-play installation and stable mechanical connection in dense rack deployments.

Suitable for

• Short-range 25GbE links between servers and top-of-rack switches
• Interconnects in data centre racks and equipment cabinets
• High-density switch-to-switch connections within the same rack or adjacent racks
• Storage array connections requiring low-latency, high-throughput links

Key specifications

• Length: 5 metres
• Connector type: SFP28 male-to-male
• Rated data rate: 25 Gbit/s
• Cable type: Direct Attach Copper (twinax)
• Use case: short-range, rack-level interconnects
• Latency: low, suitable for latency-sensitive applications

How to use

Install the cable by inserting each SFP28 male connector into the corresponding SFP28 port on your network devices until it clicks into place. Ensure both ports support 25GbE or compatible SFP28 interfaces and that devices are powered down or configured according to vendor guidelines if hot-plug restrictions apply. After connection, verify link status and negotiate speed in the device management interface; most systems will detect the DAC and establish a 25 Gbit/s link automatically.

Recommendations

Use this DAC cable for short, intra-rack or adjacent-rack connections where 5 m reach is adequate. Avoid tight bends and excessive pulling forces; maintain the cable bend radius recommended for twinax assemblies. For longer distances or where optical isolation is required, consider appropriate optical transceivers and fibre cabling instead.
