JTOPTICS QSFP56 passive copper cable assembly feature eight differential copper pairs, providing four data transmission channels at speeds up to 56Gbps (PAM4) per channel, and meets 200G Ethernet and InfiniBand Enhanced Data Rate (EDR) requirements. Available in a broad range of wire gages-from 26AWG through 30AWG-this 200G copper cable assembly features low insertion loss and low cross talk. QSFP56 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. 200G QSFP56 DAC cables are suitable for very short links and offer a cost-effective way to establish a 200-Gigabit link between QSFP-200G ports of switches/routers within racks and across adjacent racks.Hot-pluggable QSFP56 form factorData rate up to 212.5Gbps4x 53Gb/s PAM4 modulationQSFP56 MSA compliantOperating case temperature of 0-70°CSingle 3.3V supply voltageBit Error Rate (BER) bette..
