40G low-cost device interconnection solution -QSFP+ DAC high-speed cable

High-speed cables are fixed components that support high-speed data transmission. High-speed cables are widely used in short-distance data centers due to their cost and energy saving advantages. It can be connected to switches, servers, routers, network interface cards (nics), host bus adapters (Hbas) that provide high density and high data throughput.

40G QSFP+DAC high-speed cables can be divided into 40G QSFP+ to QSFP+DAC and 40G QSFP+ to 4xSFP+DAC.

Our 40G QSFP+ DAC high-speed cable complies with QSFP MSA, IEEE802.3ba, infiniband QDR specifications, and ROHS certification. It has a total bandwidth of 40Gb/s, an operating voltage of 3.3V, a power consumption of <1.5W, an EMI resistant metal housing, and cable diameters ranging from 30 AWG to 24 AWG.

40G QSFP+ high-speed cable (DAC) uses copper cable as transmission medium, both passive and active. 40G QSFP+ passive high-speed cables do not require power supply. The transmission distance is less than 5M, and the power consumption is low, but the transmission distance is also short. A 40G QSFP+ active high-speed cable has a longer transmission range.

To meet the growing demand for high-speed data, many data centers are migrating from 10GB to 40GB or even 100GB. High-speed cable DAC is the most popular solution for 40G network cabling due to its low cost.
