400G OSFP_4X100G QSFP56 passive copper cable assembly feature sixteen differential copper pairs, providing eight data transmission channels at speeds up to 56Gbps(PAM4) per channel, and meets 4X100G Ethernet and InfiniBand High Data Rate(HDR) requirements. Available in 26AWG and 30AWG wire gauges, this 400G OSFP_4X100G QSFP56 copper cable assembly features low insertion loss and low crosstalk. 400G OSFP_4X100G QSFP56 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.
