400G QSFP-DD to 4X100G QSFP56 Passive Direct Attach Copper Twinax Cable 2.5M
General Description
QSFP-DD_4XQSFP56 passive copper cable assembly feature sixteen differential copper pairs, providing eight data transmission channels at speeds up to 56Gbps(PAM4) per channel, and meets 400G Ethernet requirements. Available in a broad rang of wire gauges-from 30AWG through 28AWG-this 400G copper cable assembly features low insertion loss and low cross talk.
QSFP-DD_4XQSFP56 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.
