800G QSFP-DD to 2x400G QSFP-DD Passive High Speed Direct Attach Copper Cable 0.5M

 

Description

QSFP-DD_2QSFP112 passive copper cable assembly feature sixteen differential copper pairs, providing eight data transmission channels at speeds up to 100Gbps(PAM4) per channel, and meets 2X400G Ethernet and InfiniBand Next Data Rate(NDR) requirements. Available in 26AWG and 30AWG wire gauges, this 800G copper cable assembly features low insertion loss and low crosstalk.
QSFP-DD_2QSFP112 passive copper cable 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.
