To provide higher capacity networks, 40-Gb/s transmission systems are under active development and their cost is on the way to be competitive with one of 410 Gb/s. However, lower tolerance linear nonlinear fiber impairments remains a major drawback for field deployment. address issue impairments, coherent detection multilevel formats polarization division multiplexing appears as promising solution by reducing symbol rate 10 Gbaud. Indeed, such based have already demonstrated an improved...
Mode-division multiplexing is demonstrated over five modes for the first time. Five data streams are modulated at 100Gb/s with PDM-QPSK modulation format, multiplexed altogether, transported 40km few-mode fiber, demultiplexed, and successfully recovered.
Imbalances between the four sampling channels of a coherent detector with polarization diversity can rapidly degrade system performance. One these imbalances, namely receiver skew, becomes increasingly important when higher symbol rates, modulation orders, and low roll-off pulse shapes are used. Here, we evaluate performance skew compensation based on complex-valued multiple-input multiple-output 4 × 2 adaptive equalizer that is tolerant to large residual chromatic dispersion. In addition,...
