400G QSFP-DD DAC enables high-bandwidth 400G links and supports 400G Ethernet rate. It is high-speed, cost-effective alternatives to fiber optics in 400G Ethernet applications. The 400G QSFP-DD DAC cable contains 16 high-speed copper pairs, each operating at data rates of up to 53Gb/s, which are suitable for very short links and offer a cost-effective and power-efficient way to establish a 400-Gigabit link between QSFP-400G ports of switches/routers within racks and across adjacent racks.

The 400G OSFP AOC is a 400 Gb/s parallel active optical cable, which transmits parallel 8×50 Gb/s PAM4 signals over multi-mode fiber (MMF) OM3 cables up to 100m.
