We discuss the use of a coherent digital receiver for the compensation of linear transmission impairments and polarization demultiplexing in a transmission system compatible with a future 100-Gb/s… (More)
111-Gb/s transmission combined with 2 times 43-Gb/s and 8 times 10.7-Gb/s on a 50-GHz grid over 1,040-km field fiber and two ROADMs is demonstrated, showing the feasibility of 100G overlaying… (More)
In this paper we describe the boundary conditions for upgrading existing 10 G optical transport networks with 40 G and 100 G channels and the operational issues in multi-rate optical networks.
We demonstrate the transmission of 111-Gb/s POLMUX-RZ-DQPSK over an 1140 km EDFA-only link in the presence of 10times10.7-Gb/s OOK neighbours and show the impact of channel spacing on the cross-talk.
We present 10-Gb/s transmission with a directly modulated laser (DML) avoiding inline dispersion compensating by electronic precompensation. To apply this technique of electronic dispersion… (More)
We demonstrate transmission of a 111-Gb/s coherent polarization-multiplexed return-to-zero differential quadrature phase-shift keying signal over 1040-km field-deployed fiber together with different… (More)
We present a transmitter setup for optical duobinary transmission with reduced complexity resulting from a simple precoder and from using a standard single-arm Mach-Zehnder modulator. With this… (More)
We demonstrate joint polarization carrier phase estimation for XPM-limited channels with significant improvements over standard methods, demonstrated on measurements of 43 Gb/s NRZ-CP-QPSK with 10.7… (More)
In this paper, we experimentally investigate the tolerance of 111-Gb/s polarization multiplexed-return to zero-differential quadrature phase-shift keying (POLMUX-RZ-DQPSK) to the different nonlinear… (More)
In DWDM field experiments over 1047 km of standard fiber and in simulations we analyze the impact of crosstalk on a 43 Gb/s RZ-DQPSK channel both by 10.7 Gb/s OOK and 43 Gb/s RZ-DQPSK neighbors at 50… (More)
