Transmitter-Aware Fast FFE Coefficients Distribution for PAM4 Links in Sub-Microsecond Optical Switching Networks
We experimentally demonstrate a fast and energy-efficient FFE coefficient distribution method in dynamic 50 GBaud PAM4 optical circuit switch (OCS) based data center networks. Results show convergence latency < <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$4.5 ~\text{ns}, 46 \%$</tex> power savings via tap count optimization, negligible ROP impact, and +/-0.3 dB TDECQ tolerance. ©2025 The Author(s)
