Product Features
Technical Overview
This cable operates as a 40GBASE-CR4 compliant passive direct-attach copper (DAC) solution, utilizing twinaxial cable construction to support 40 Gigabit Ethernet speeds. The passive design means it does not require external power, relying on the host device's electrical signaling for data transmission, which simplifies deployment and reduces power consumption compared to active optical cables.
The QSFP+ connectors provide a hot-pluggable interface that supports high-density port configurations. With a reach of 1.6 ft, this cable is ideal for top-of-rack switching, server-to-switch connections, and inter-chassis links where minimal cable management and reduced signal attenuation are priorities.
Key Product Advantages
This DAC cable delivers several practical benefits for network infrastructure, focusing on reliability, compatibility, and ease of use in high-speed environments.
