400G QSFP-DD Passive Direct Attach Copper Twinax Cable FYDA-OS456-**MB**
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. Remark: Above “**”refers to the corresponding meters. “**”refers to the optional cable diameter.
