## Long description

DIGITUS DN-81242 is a 2 m passive Direct-Attach Copper (DAC) twinax cable with SFP28 connectors designed for short-reach 25G interconnects. The assembly provides a shielded twinax copper cable with pluggable SFP28 ends, compatible with SFF-8402 and SFF-8432 connector specifications, and is intended for use in data centers and high-speed networking environments where short-distance, low-latency links are required.
Advantages
This passive DAC cable supports data rates up to 25.88243 Gbps while operating from a +3.3V supply and follows the SFF-8402 electrical interface. Its AWG 30 twinax construction and shielded design minimize signal loss and electromagnetic interference for short links. The hot-pluggable SFP28 20-pin footprint simplifies installation and replacement, and the cable is rated for an operating temperature range of 0 to 70°C.
Suitable for
 Short-reach connections between two SFP28 ports (switch-to-switch)
 Connections from servers to switches in data centers
 High-performance computing and storage array interconnects
 Telecommunication systems requiring 25G links

How to use
Insert each SFP28 connector into the corresponding SFP28 port on the devices to be connected, ensuring the latches engage securely. Use the cable for short-distance links—typically 1–2 m—to achieve the best performance; the product supports maximum lengths commonly up to 5 m for passive DAC. No additional configuration is required at the cable level; devices may need standard interface configuration on the network equipment.
Usage recommendations
Use this passive DAC cable for direct short links inside racks or between adjacent racks. Avoid sharp bends and excessive mechanical strain on the cable and connectors, and operate within the specified 0–70 °C temperature range. For longer distances or where signal conditioning is required, consider active optical or active copper alternatives.
