Signal-to-noise ratio monitoring of optical data using narrowband RF analysis at the half-clock frequency

A novel technique for monitoring the in-band SNR of an optical data channel is demonstrated. The technique utilizes an inherent symmetry present the RF spectrum at half the data clock frequency, is highly sensitive and potentially low-cost.
