400G DAC

400G QSFP-DD PAM4 DAC

Compatible with IEEE 802.3bj and IEEE 802.3cd
Supports aggregate data rates of 400Gbps(PAM4)
Optimized construction to minimize insertion loss and cross talk 
Pull-to-release slide latch design
Straight and break out assembly configurations available
Customized cable braid termination limits EMI radiation   
Customizable EEPROM mapping for cable signature
 
  • USource QSFP-DD passive copper cable assembly feature eight differential copper pairs,providing four data transmission channels at speeds up to 56Gbps(PAM4) per channel, and meets 400G Ethernet and InfiniBand Enhanced Data Rate(EDR) requirements. QSFP-DD uses PAM4 signals for transmission, which doubles the rate. 
    400G QSFP-DD Direct Attach Cables are available with 28 AWG. Standard lengths are 0.5m, 1m, 2m, 2.5m.
    400G QSFP-DD to 2x200G QSFP56 Breakout Direct Attach Cables are also available with lengths from 0.5 meter to 2 meter.
