Electronic dispersion precompensation for 10.709 Gbit/s NRZ-OOK using InP and LiNbO 3 Mach-Zehnder modulators

It is shown that electronic precompensation using InP and LiNbO3 dual-drive Mach-Zehnder modulators effectively reduces the degradation caused by chromatic dispersion for 10.709 Gbit/s on-off-keying modulation. Transmission results for a recirculating loop experiment with nonzero dispersion shifted fibre and a straight-line experiment with non-dispersion-shifted fibre achieve a dispersion tolerance of about 4 ns/nm with precompensation.
