The Cisco QSFP-4SFP10G-CU5M is a 40GBASE-CR4 to 4x 10GBASE-CU QSFP+ to four SFP+ copper direct-attach breakout cable. This passive copper splitter cable is suitable for very short distances and offers a highly cost-effective way to connect within racks and across adjacent racks. It connects a 40G QSFP+ port of a Cisco switch on one end to four 10G SFP+ ports of a Cisco switch on the other end. The cable is 5 meters long and operates over passive copper, which requires no additional power to ensure quality connectivity. It is designed to meet the Multi-Source Agreement (MSA) standards for form factor and performance, ensuring compatibility with a wide range of Cisco networking equipment including Nexus and Catalyst series switches.
