Cisco QSFP-H40G-CU4M

The Cisco QSFP-H40G-CU4M is a high-speed, 40 Gigabit Ethernet (GbE) copper cable assembly. It is a Quad Small Form-factor Pluggable (QSFP) transceiver module that supports data rates of up to 40 Gbps over copper cables. The "CU" in the model name stands for copper, indicating that it is designed for use with copper cables rather than optical fibers. The "4M" indicates that the cable length is 4 meters. This Cisco QSFP module is commonly used in data centers and high-performance computing environments for short-range, high-bandwidth connectivity between network switches, routers, and servers.
