The Cisco 40GBASE-CR4 QSFP+ (Quad Small Form-Factor Pluggable Plus) Direct Attach Copper (DAC) cables are designed for very short distances and offer a highly cost-effective way to establish a 40-Gigabit link between QSFP+ ports of Cisco switches within racks and across adjacent racks. These cables provide a low-latency, high-bandwidth connection and are available in various lengths, including passive options from 0.5 to 5 meters and active copper options for 7 to 10 meters. They are hot-swappable, meaning they can be plugged into a 40-Gigabit Ethernet Cisco QSFP+ port without having to power down the system. The cables are compliant with the IEEE 802.3ba 40GBASE-CR4 standard and the SFF-8436 MSA.
