Description
The Cisco QSFP-H40G-CU4M is a 40 Gigabit Ethernet (40 Gbps) QSFP+ Direct Attach Copper (DAC) cable designed for short-distance connections within a rack or between adjacent racks. It uses four copper twinax cables to transmit data and supports the 40GBASE-CR4 standard.
DACs are a cost-effective solution for short-distance connections compared to fiber optic cables. They are also easier to install and require less power. However, DACs have a shorter reach than fiber optic cables.
