Chromatic dispersion compensation in coherent transmission system using digital filters
Tianhua Xu,Gunnar Jacobsen,Sergei Popov,Jien Li,Evgeny Vanin,Ke Wang,Ari T. Friberg,Yimo Zhang +7 more
TL;DR: A comparative analysis of three popular digital filters for chromatic dispersion compensation: a time-domain least mean square adaptive filter, aTime-domain fiber dispersion finite impulse response filter, and a frequency-domain blind look-up filter.
Journal ArticleDOI
Analytical estimation of phase noise influence in coherent transmission system with digital dispersion equalization
TL;DR: A novel investigation on the enhancement of phase noise in coherent optical transmission system due to electronic chromatic dispersion compensation is presented and the performance of differential QPSK demodulation system is compared.
Journal ArticleDOI
Influence of birefringence dispersion on a distributed stress sensor using birefringent optical fiber
TL;DR: In this article, a distributed stress sensor with a white-light scanning interferometer is used to detect stress distribution by analyzing polarization mode coupling caused by forces exerted on PMFs (polarization maintaining fibers).
Journal ArticleDOI
Receiver implemented RF pilot tone phase noise mitigation in coherent optical nPSK and nQAM systems
TL;DR: It is found that equalization enhanced phase noise--which appears as correlated pure phase noise, amplitude noise and time jitter-cannot be efficiently mitigated by the use of an (optically or electrically generated) RF pilot tone.
Journal ArticleDOI
EEPN and CD study for coherent optical nPSK and nQAM systems with RF pilot based phase noise compensation
TL;DR: A detailed study comparing two filters for the CD compensation namely the fixed frequency domain equalizer (FDE) filter and the adaptive least-mean-square (LMS) filter provides important novel physical insight into the equalization enhanced phase noise (EEPN) influence on the system bit-error-rate versus optical signal-to-noise-ratio (OSNR) performance.
