## Summary description

Copper SFP28 direct attach (DAC) twinax cable by CBO, model SFP28-DAC-3M-EE-BL. Length 3 meters, male-to-male connectors, supporting 25 Gbit/s links for short-reach 25GbE or compatible network ports. Designed for low-latency, energy-efficient connections between switches, NICs and servers in data center racks where a fixed, cost-effective high-speed link is required.

## Long description

The BlueOptics SFP28 Twinax Direct Attach Cable SFP28-DAC-3M-EE-BL is a 3 meter copper twinax cable with male-to-male SFP28 connectors designed for short-reach 25 Gbit/s links. It provides a fixed, low-latency connection option for data center equipment such as switches, network interface cards (NICs) and servers where a cost-effective, energy-efficient high-speed link is required. The cable is intended for direct connection between compatible 25GbE ports without the need for optical transceivers or patch panels.
Advantages
This SFP28 twinax DAC offers a low-power, low-latency physical connection that reduces both heat and power consumption compared with active optical solutions. The integrated male-to-male SFP28 connectors simplify installation and eliminate the need for separate transceivers, lowering total hardware cost. With a fixed 3 m length, the cable provides predictable signal integrity for short-reach links inside racks or between adjacent racks and is suitable for environments that prioritise straightforward, high-bandwidth connectivity.
Suitable for
Direct connections between 25GbE-capable switches
Server to NIC links in rack-mounted systems
Short-reach interconnects in data center top-of-rack and leaf-spine deployments
Cost-sensitive high-speed links where optical transceivers are not required
Key specifications
Connector type: Male SFP28 to Male SFP28
Cable type: Copper twinax
Nominal data rate: 25 Gbit/s
Length: 3 meters
Intended reach: Short-reach, within or between adjacent racks
Latency: Low, suitable for latency-sensitive applications
Power: Passive/low-power direct attach design
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the devices to be connected, ensuring correct orientation and a secure latch engagement. Use the cable for direct device-to-device links where both ports support 25GbE and SFP28 form factor. Avoid excessive bending or mechanical strain on the cable near the connectors and route the cable to prevent sharp edges or pinch points. Verify link status on connected devices and consult device documentation for any port configuration or firmware requirements.
Usage recommendations
For reliable operation, confirm compatibility of the SFP28 ports with passive twinax DACs and use this 3 m cable for short interconnects within racks or between adjacent racks. Maintain bend radius within manufacturer guidelines, avoid prolonged exposure to high temperatures, and replace the cable if connector latches or the cable jacket show damage. Use in environments where reduced power consumption and low latency are priorities.
