We measure the system impacts due to the amplitude of group-delay (GD) ripple in single and cascaded chirped fiber Bragg gratings (CFBGs). Signals with smaller pulse width result in smaller performance variation at the same data rate. A 65-ps peak-to-peak GD ripple induces 0.9, 1.7, and 2.7 dB maximum penalties for 10, 20, and 40-Gb/s, respectively. We also find that cascading gratings with random...
We show that the clock signal can be regenerated, or suffer fading, through a dispersive fiber link for NRZ or RZ data, respectively. The clock regenerating and fading effects can be used to monitor the accumulated chromatic dispersion for unambiguous windows of +/-900 ps/nm for NRZ systems and +/-640 ps/nm for RZ systems at 10 Gbit/s. We also demonstrate dynamic dispersion compensation for both NRZ...
