Cisco QSFP-H40G-CU3M

The Cisco QSFP-H40G-CU3M is a high-speed, 40 Gigabit Ethernet (GbE) copper cable designed for use with Cisco networking equipment. It is a Quad Small Form-factor Pluggable (QSFP) cable, which means it has four independent data transmission channels. The "CU" in the model name stands for copper, indicating that it is a copper-based cable rather than a fiber optic cable. The "3M" indicates that the cable is 3 meters in length. This cable is commonly used for short-range, high-speed data transmission within data centers or between networking devices.
