Product Description

★Description

A low-cost solution for short-distance connection within and between data center cabinets,400G QSFP-DD  DAC Direct Attach Cable (DT-DAC-400G-QSFP-DD),DAYTAI QSFP-DD passive copper cable assembly feature eight differential copper pairs,providing four data transmission channels at speeds up to 56Gbps(PAM4) per channel,and meets 400G Ethernet and InfiniBand Enhanced Data Rate(EDR) requirements.Available in a broad rang of wire gages-from 28AWG through 30AWG-this 400G copper cable assembly features low insertion loss and low cross talk. QSFP-DD uses PAM4 signals for transmission, which doubles the rate. However, there are more stringent requirements for cable insertion loss. For detailed requirements, please see High Speed Characteristics.Compatible With the Brand:Cisco,Juniper,Brocade,Arista,Mellanox,HPE, Force10,Huawei...Etc is Optional,Length: 0.5m,1m,1.5m,2m, 3m...is Optional.
