With the rapid rise of the Internet of Things, cloud computing, artificial intelligence, and big data applications, the data transmission rate of servers, routers, switches and data storage devices is also increasing, and data centers will also face high bandwidth, high reliability and low latency. challenges, especially for data transmission up to 400G.

To achieve high data transmission, this requires cost-effective, stable and reliable data transmission cables and connectors. At the same time, the DAC high-speed cable has the advantages of high simplicity, flexibility and low power consumption, and is a cost-effective solution for realizing short-distance high-speed transmission in the data center.

This article will introduce the 400G DAC high-speed cable for you.

Among various types of DAC cables, compared with SFP series (including SFP+, SFP28, SFP56), QSFP series (including QSFP+, QSFP28, QSFP56, QSFP-DD) are 4-channel data transmission, and the data capacity is larger, from 40G to 400G , QSFP-DD like 400G is very suitable for data center applications such as servers, routers, switches and data storage with current ultra-high data transmission.

Although the data rate of the SFP series is relatively low, due to the more use of LEONIzell dielectric technology, the bending performance is better in indoor wiring, and the insertion loss is 10% lower than the industry average.

The 400G QSFP-DD DAC has a data rate of up to 425Gbps, adopts 8-channel 53Gb/s PAM4 modulation, and meets the requirements of 400G Ethernet and InfiniBand EDR. Various wire gauges are available from 28AWG to 30AWG. The length is 0.5 to 2.5 meters, with the advantages of low insertion loss and low crosstalk.

It is mainly used in switches, servers and routers, data center networks, storage area networks, storage area networks, high performance computing, telecom and wireless infrastructure, medical diagnostics and networking test and measurement equipment.
