Description
DAC QSFP-40G-CU7M high-speed cable offers low power consumption and low latency, making it 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 cords
DAC QSFP-40G-CU7M Product Overview
DAC QSFP-40G-CU7M is a Cisco, Huawei compatible direct-attach copper QSFP+ cable, which is designed, programmed and tested to work with brand compatible switches and routers and complies with MSA industry standards.
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.
