## Summary description

The Intellinet QSFP+ 40G Passive DAC Twinax Cable is designed for high-speed data transmission. Measuring 0.5 meters, it features QSFP+ connectors on both ends, ensuring compatibility with various devices. This MSA-compliant cable utilizes direct attach copper technology and AWG 30 for optimal performance and minimal signal loss. Ideal for data centers and networking applications, it provides a reliable and efficient solution for connecting equipment.

## Long description

The Intellinet QSFP+ 40G Passive DAC Twinax Cable (0.5 m) is a short-reach direct attach copper solution with QSFP+ connectors at both ends. MSA-compliant and built with AWG 30 twinax, it is intended for high-speed 40 Gbps connections between switches, routers, servers and storage in data centers and rack environments. The passive design eliminates the need for separate transceivers and is optimized for low power consumption and minimal signal loss over short distances.
Advantages
This passive QSFP+ 40G DAC cable consumes virtually no power (under 0.15 W), produces no operational heat, and supports operation in wide temperature ranges up to 70°C (158°F). Its simple twinax construction reduces purchase and deployment costs compared with fiber optic systems since no separate transceivers are required. The cable offers lower latency than RJ45 twisted-pair patch cables and supports hot swapping for fast equipment changes. Note that the passive DAC design is intended for short-distance links and reaches its practical limit at approximately 7 m (23 ft.).
Suitable for
Top-of-Rack (ToR) connections between switches and servers
Adjacent-rack or short inter-rack links
40GbE switch stacking and uplinks
Server-to-storage short-reach connections in data centers

How to use
Plug the QSFP+ connectors directly into compatible QSFP+ ports on switches, routers, servers or storage devices. Ensure both endpoints are powered down or support hot swapping per your equipment documentation before insertion if required. Verify device compatibility with MSA-compliant QSFP+ ports and confirm that the 0.5 m length and passive DAC mode meet your distance and thermal requirements. No additional transceivers or configuration are generally necessary for standard direct attach use.
Usage recommendations
Use this passive DAC cable for short-distance, high-bandwidth links in data center and rack environments. Confirm compatibility with your vendor equipment (MSA-compliant QSFP+ ports) and avoid using passive DACs where link distance requirements exceed their practical limit (~7 m). For longer reaches or optical isolation, consider fiber optic solutions with appropriate transceivers.
