We propose a dual-channel nonlinear optical sampling gate using a shared highly nonlinear fiber for synchronized monitoring of high-speed optical communication waveforms. Common nonlinear gating suppresses channel-to-channel mismatch and enables software-synchronized waveform reconstruction with low-bandwidth detection, providing a compact route toward multi-lane timing-skew and signal-quality monitoring in datacenter optical interconnects.
