Infraeo Inc.'s low-power 400G QSFP-DD active electrical cable series includes two variants: 8x50G QSFP-DD-to-OSFP 4x100G and 8x50G QSFP-DD-to-QSFP112 4x100G active electrical cable (or, active direct attached cable). This product series enables the AI clusters to adopt H100 GPU and Bluefield DPU accelerators with the 50G PAM4-based 400G ethernet networking. By converting the 8x50G PAM4 into 4x100G PAM4 through a power DSP technology, the 8x50G QSFP-DD AEC series can be connected to any combinations of 100G PAM4 network interfaces through the parallel Twinax copper breakout cables. AI cluster infrastructure users may reuse their existing 400G networking infrastructure or use 400G.
Judge’s Comment: “This is a well-engineered AEC with an integrated gearbox and low power consumption.”
