We demonstrate a chromatic dispersion monitoring technique for systems using dual-drive Mach-Zehnder modulators. A RF monitoring tone, at switched frequencies, is phase-modulated onto the optical signal with the existing modulator. Better monitoring sensitivity and range is achieved compared to conventional systems employing an amplitude-modulated tone.
