The Compatible 400G QSFP-DD to 4x 100G QSFP56 Active Optical Breakout Cable (AOC) provides a high-density, high-speed solution for connecting 400G networking switches to four individual 100G QSFP56 ports. Utilizing 8x50G PAM4 modulation on the 400G QSFP-DD end and splitting into 2x50G PAM4 channels across four separate 100G QSFP56 ends, this active optical breakout cable ensures seamless data distribution across modern data center architectures.

Designed for low latency and reduced power consumption, this breakout AOC offers an ideal alternative to copper cables for medium-range interconnects, delivering power-efficient 400G to 100G Ethernet connectivity across enterprise networks and high-performance computing environments.

Key Features

  • 400G to 4x100G Breakout Architecture: Splitting a single 400G QSFP-DD port into four 100G QSFP56 endpoints for efficient port utilization.
  • Advanced Modulation Technology: Leverages 8x50G PAM4 on the QSFP-DD connector end and 2x50G PAM4 on each QSFP56 connector end.
  • Low Power & High Performance: Features energy-efficient operation with power consumption of ≤10W for QSFP-DD and ≤3W for each QSFP56 transceiver end.
  • Durable & Flexible Design: Built with a Low Smoke Zero Halogen (LSZH) cable jacket and a tight 30mm minimum bend radius for easy routing in high-density racks.
  • Data Center Ready: Fully compliant with 400G/100G Ethernet industry standards for switch-to-switch and switch-to-server interconnects.
