The Cisco QSFP-4X10G-AC7M is a direct attach breakout copper cable manufactured by Cisco. It features a QSFP form factor on one end and breaks out to four SFP+ connectors on the other, supporting transmission speeds of up to 40 Gbps over its total length of 7 meters.
This passive twinaxial cable enables point-to-multipoint connections within racks or across adjacent cabinets in high-density data center environments. The single-port QSFP interface connects directly into switches with quad-lane interfaces, while the four individual SFP+ ends support separate 10 Gigabit Ethernet ports for downstream devices.
