A 51.2Tb/s switch requires 512 lanes operating at 106Gb/s PAM-4. Such a massive integration of electrical SERDES is restrained by three factors: First, a large switch die size (>25"25mm2) substantially lowers yield and prohibitively increases cost. Second, a large-size package suffers more than 10dB insertion loss from combined TX and RX traces. Considering practical equalization capabilities of a long-reach system (>30dB), 10dB package loss significantly limits the available channel reach. Lastly, channel reflection and
