We demonstrate a scalable and reconfigurable optical TDL for multichannel equalization and correlation of 20-Gbaud QPSK signals using nonlinear wave mixing and a Kerr frequency comb. The two/three-tap OTDL is demonstrated to simultaneously equalize a first signal and to search two/three-symbol patterns on another channel.
