For the first time, 80/40 Gbit/s/lambda Star-16QAM WDM transmission with/without polarization multiplexing has been demonstrated over 720/1200 km SSMF on a 50 GHz frequency grid applying enhanced techniques for electronic distortion equalization.
Key issues related to the modeling of electro-optic transmitters are discussed in this paper. These topics include limitations resulting from the transmitter frequency response and driving electronics. Simulation results illustrate the importance of realistic modeling in high-speed systems.
Key issues related to the design of electro-optic transmitters and receivers are discussed in this paper. These topics include limitations in 100G transmission systems resulting from the frequency response of devices and non-linear effects. Numerical simulations illustrate the importance of realistic modeling in such high-speed systems.
