Next Generation Transmission Fiber for Coherent Systems
Optical Communication Fiber optics optical communications
2010/6/9
The impact of fibre parameters on coherent system performance is presented. Not unlike intensity transmission, low loss, large effective area and high local dispersion are preferred for optimizing coh...
Nonlinear Penalty Reduction Induced by PMD in 112 Gbit/s WDM PDM-QPSK Coherent Systems
Nonlinear Penalty PMD WDM PDM-QPSK Coherent Systems
2009/7/20
We show by simulation that when linear PMD is fully compensated by the receiver, the presence of DGD along the link reduces the amount of residual nonlinear penalty in 112 Gbit/s PDM-QPSK coherent sys...
The signal and local oscillator acquire identical nonlinear phase shifts during propagation in a self-homodyne coherent system. We exploit this to achieve cancellation of the phase distortion caused b...
Compensation of fibre impairments in digital coherent systems

Coherent detection combined with digital signal processing (DSP) is a symbiotic relationship. Not only does DSP relax the requirements on the coherent receiver but it permits digital compensation of f...
