Description
The 200G QSFP56 Passive Direct Attach Copper (DAC) Cable is a high-speed twinax copper interconnect designed for 200Gbps Ethernet and InfiniBand 4x HDR applications. Featuring QSFP56 connectors on both ends, it uses four high-speed PAM4 channels with up to 56Gbps per channel to deliver 200G-class connectivity with low power consumption and low latency. Its optimized copper construction helps reduce insertion loss and crosstalk for reliable signal integrity at high data rates. Available in 26 AWG and 30 AWG configurations with lengths up to 5m, the cable provides flexible short-distance connectivity for data centers, HPC environments, networking, and telecommunications applications.
