The Cisco QSFP-4SFP10G-CU is a 40G to 4x10G passive Twinax copper DAC breakout cable, designed to split a single QSFP+ 40Gbps connection into four individual SFP+ 10Gbps links. Ideal for data centers and high-performance networks, this direct-attached breakout cable enables efficient, cost-effective short-range connectivity between switches, routers, and servers. Supporting passive design, it requires no additional transceivers, reducing power consumption and operational costs. Typically used for distances up to 5 meters, the QSFP-4SFP10G-CU provides low-latency, high-speed data transfer, making it suitable for environments needing both 40G and 10G connectivity in a flexible, space-saving solution.
