## Summary description

The Intellinet QSFP+ 40G Passive DAC Twinax Cable is a 3m direct attach copper cable designed for high-speed data transmission. It features QSFP+ connectors and is MSA-compliant for maximum compatibility. Ideal for connecting switches and servers in data centers.

## Long description

The Intellinet QSFP+ 40G Passive DAC Twinax Cable is a 3 m direct attach copper cable designed for high-speed short-range connections in data centers and server rooms. With QSFP+ connectors on both ends and MSA compliance, the cable provides a low-power, low-latency link between switches, routers, servers and storage for applications such as Top-of-Rack, adjacent-rack connections and 40GbE switch stacking.
Advantages
This passive QSFP+ 40G DAC Twinax cable consumes under 0.15 W, allowing near-zero power use and minimal heat generation during operation. Its twinax copper construction and integrated QSFP+ terminations eliminate the need for separate transceivers, reducing procurement costs and simplifying deployment. The cable supports data rates up to 40 Gbps with lower latency compared to RJ45 twisted-pair patch cables. Passive design and rugged construction make it convenient for hot swapping and reuse without the cleaning and inspection required for fiber connectors. Note that the passive DAC reaches its practical transmission limit at around 7 m.
Suitable for
Top-of-Rack (ToR) switch-to-server connections
Adjacent-rack links and short interconnects
40GbE switch stacking and spine-leaf aggregation within racks
High-bandwidth server-to-storage short-range links

How to use
Insert the QSFP+ connector of one cable end into the QSFP+ port of the first device (switch, router or server) and the other end into the corresponding QSFP+ port of the second device. Ensure ports are powered down or follow your site’s hot-swap procedure if connecting between active devices. Verify link status on both devices after connection; the cable requires no additional transceivers or configuration to establish a physical 40G link when used with compatible equipment.
Usage recommendations
Use this passive 3 m QSFP+ DAC Twinax cable for short-range high-bandwidth interconnects inside racks or between adjacent racks. Avoid using passive DACs for links longer than their supported range (practical limit ~7 m). Confirm MSA compatibility with your switch or router vendor and follow standard ESD and handling procedures when connecting or disconnecting the cable.
