Why choose it

With its passive design, this cable offers an energy-efficient and cost-effective solution for very short reaches, eliminating the need for transceivers on both ends. It provides reliable performance with minimal latency, making it ideal for top-of-rack to server connections. The robust twinax construction ensures excellent signal integrity over the specified distance, while the low power draw contributes to overall energy savings in the data centre.

Ideal use cases

• Connecting servers to top-of-rack switches in data centres
• Interconnecting network devices within a rack
• Storage area network (SAN) links
• High-performance computing clusters

Good to know

This cable is designed for 10 Gigabit Ethernet, Fibre Channel, and InfiniBand networks. It is also backward compatible with lower speeds, offering flexibility in mixed-speed environments. The passive DAC design means no additional power is required, and the hot-pluggable SFP+ connectors allow for quick installation and replacement. With universal compatibility, it works seamlessly across major networking hardware vendors.
