TL;DR: Using the analytical solution an upper bound on the number of taps required to compensate chromatic dispersion is obtained, with simulation revealing an improved bound of 2.2 taps per 1000ps/nm for 10.7GBaud data.

TL;DR: In this article, a theoretical analysis of the dual-polarization constant modulus algorithm is presented, where the control surfaces several different equalizer algorithms are derived, including the decision-directed, trained, and the radially directed equalizer for both polarization division multiplexed quadriphase shift keyed (PDM-QPSK) and 16 level quadrature amplitude modulation (PDm-16-QAM).

TL;DR: In this paper, 16 researchers, each a world-leading expert in their respective subfields, contribute a section to this invited review article, summarizing their views on state-of-the-art and future developments in optical communications.

TL;DR: Results of a 42.8Gbit/s nonlinear transmission experiment, using polarization multiplexed QPSK data at 10.7GBaud, with 4 bits per symbol is presented, which allows the digital coherent receiver to be compensated digitally after transmission over 6400km of standard single mode fiber.

TL;DR: In this article, the authors investigated blind equalization and carrier phase recovery in a simulated 14 Gbaud 16-QAM optical coherent system and showed that the RDE algorithm can compensate up to 1000 ps/nm of CD in the system with performances comparable to the decision-directed equalizer.
