Overview
The QSFP-4X10G-AC7M cable assembly bridges the gap between 40 Gigabit Ethernet (40GbE) and 10 Gigabit Ethernet (10GbE) devices within a data center. It accomplishes this by featuring a QSFP+ connector on one end for connection to a 40GbE port and four SFP+ connectors on the other end for connecting to four 10GbE devices. This cable utilizes copper wires with active electronics to transmit data at speeds of up to 40 GB/s overall.
Due to its copper construction, the QSFP-4X10G-AC7M is most suitable for short distances, typically limited to 7 meters (around 23 feet). This makes it ideal for cost-effective connections within a single rack or between nearby racks. These assemblies are popular for their ease of use, low power consumption, and affordability compared to fiber-optic options for short distances. However, keep in mind that copper cables are more susceptible to signal interference and cannot match the reach of fiber. When choosing a QSFP-4X10G-AC7M cable, ensure compatibility with your devices, and remember that it's a great option for short-range data center connections.
