Overview
The QSFP-4SFP10G-CU5M cable, also known as a QSFP+ to SFP+ DAC (Direct Attach Copper) cable, 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 separate 10GbE devices. Unlike fiber optic options, this cable utilizes passive copper wires to transmit data, making it a more cost-effective solution for shorter distances, typically around 5 meters (16.4 feet). This range makes it ideal for connections within a single rack or between nearby racks. The QSFP-4SFP10G-CU5M is popular for its ease of use, low power consumption, and affordability. However, keep in mind that copper cables are more susceptible to interference and have limited reach compared to fiber-optic options. Get it at Crystal Computers.
