DAC QSFP-40G-CU1M offers low power consumption and low latency, making it an ideal solution for short-distance transmission (up to 7m) between data center racks, saving costs compared to a combination of modules and jumpers

DAC QSFP-40G-CU1M Product Overview

This passive Twinax copper cable supports 40 Gigabit Ethernet applications connected through QSFP+ (Mini-GBIC) ports. This copper QSFP+ cable is hot-swappable, making upgrades and replacements seamless by minimizing network disruptions.
Designed for high-speed performance, this low-power, low-latency QSFP+ cable is a cost-effective alternative to fiber-optic cable assemblies, supporting short-distance applications such as point-to-point in-rack network switch or server connections.
