Description
DAC QSFP-40G-CU3M is an ideal solution for short-distance transmission (up to 7m) between data center racks, and can effectively save costs compared to a combination of modules and patch cord
DAC QSFP-40G-CU3M Product Overview
This high speed direct attach cable is a cost-effective solution that provides high bandwidth and transmission rates over short distances. QSFP+ (Quad Small Form-factor Pluggable Plus) Cable Assemblies are suitable for very short distances and offer a highly cost-effective way to establish a 40-Gigabit link between QSFP+ ports of QSFP+ switches within racks and across adjacent racks. QSFP+ cables are used for 40 GbE and Infiniband standards.
A direct attach cable, short for DAC cable, is a type of factory terminated twinax cable that connects directly into transceivers and can be brought in several lengths for short distances of up to 15 meters. These cables consist of fixed lengths of shielded copper coaxial or fiber optic cable with single pluggable transceivers at either end, that have varying gauge values between 24AWG and 30AWG. The DAC cable may be capable of interconnection up to 15 meters using a twinaxial copper cable and reaches 100 meters over an active optical cable at 10Gbps, 40Gbps or higher.
