SYNOXX 400G QSFP-DD 400G PAM4 to 2x200G QSFP56 200G PAM4 Passive Copper Breakout Cable

The SYNOXX EDQD400-2QPx is a passive copper breakout cable assembly that connects one 400G QSFP-DD port to two 200G QSFP56 ports. It is designed for high-speed networking environments where a single 400G interface needs to be split into two separate 200G links.

This cable uses PAM4 signaling and optimized copper construction to help reduce insertion loss and crosstalk. It also features a pull-to-release slide latch design, customizable EEPROM mapping, and cable braid termination to help limit EMI radiation.

The EDQD400-2QPx is a strong choice for modern data centers, AI/HPC environments, storage networks, cloud infrastructure, and high-speed aggregation links.
