We use a global optimization algorithm to find the optimum fiber launch powers and dispersion map of single-channel RZ-DPSK and RZ-DQPSK systems at data rates ranging from 5 Gbit/s to 130 Gbit/s.
We present a novel, fast method for optimizing the performance of a system. It is used to optimize the dispersion map and signal power in a DQPSK 111Gb/s link.
We propose a novel technique that allows simultaneous detection of two modulated optical sub-carriers. A proof-of-principle experiment is described and subsequently the performance at high data rates… (More)
We propose a novel technique that allows direct detection of multicarrier signals without using DSP at the receiver. Performance at 55.5 Gb/s, back-to-back and after 1040 km of dispersion… (More)
Using a global optimization algorithm, we maximize the reach of DPSK and DQPSK systems including PMD and nonlinear phase noise at data rates ranging from 5 Gbit/s to 230 Gbit/s.
Digital Subcarrier Multiplexing (DSM) allows simple direct detection of spectrally efficient multicarrier signals. We show through simulations that, by using DSM, the quality of DWDM transmission… (More)
High order modulation formats have been recently used to increase the capacity as well as the reach distance of high-speed optical transmission systems. This paper will review five modulations… (More)
Advanced modulation formats using higher-order amplitude- and phase-modulation have been recently used to achieve record capacity in long-haul optical transmission systems. In this work, we evaluate… (More)
Digital Subcarrier Multiplexing (DSM) allows simple direct detection of multi-carrier signals. We show, by means of simulations, that linear equalization is more effective in increasing the… (More)
