Simultaneous chromatic dispersion, polarization-mode-dispersion and OSNR monitoring at 40Gbit/s.
A novel method for independent and simultaneous monitoring of chromatic dispersion (CD), first-order PMD and OSNR in 40Gbit/s systems is proposed and demonstrated. This is performed using in-band tone monitoring of 5GHz, optically down-converted to a low intermediate-frequency (IF) of 10kHz. The measurement provides a large monitoring range with good accuracies for CD (4742+/-100ps/nm), differe...
متن کاملEvaluation of Polarization Mode Dispersion and Chromatic Dispersion using Quantum Interferometry
The use of quantum correlations between photons to measure polarization mode dispersion (PMD) and chromatic dispersion is investigated. Two types of apparatus are discussed which use coincidence counting of entangled photon pairs to allow sub-femtosecond resolution for measurement of both PMD and chromatic dispersion, as well as separation of even-order and odd-order chromatic effects in the PM...
متن کاملAdaptive Electronic Dispersion Compensator for Chromatic and Polarization-Mode Dispersions in Optical Communication Systems
The widely-used LMS algorithm for coefficient updates in adaptive (feedforward/decision-feedback) equalizers is found to be suboptimal for ASE-dominant systems but various coefficient-dithering approaches suffer from slow adaptation rate without guarantee of convergence. In view of the non-Gaussian nature of optical noise after the square-law optoelectronic conversion, we propose to apply the h...
متن کاملPolarization mode dispersion compensation of chirped Bragg gratings used as chromatic dispersion compensators
Compensation of Polarization Mode Dispersion (PMD) induced by a chirped Bragg grating is performed using a short length of highly birefringent fiber. A recirculating loop experiment demonstrates complete PMD compensation of the chirped Bragg grating. This simple method can be extended to deterministic PMD compensation of any components. Introduction: Pulse broadening induced by PMD is now an im...
متن کاملCompensation of Polarization Mode Dispersion
The topic of thesis is “Compensation of Polarization Mode Dispersion (PMD)” in Fiber optics communication and its impact on high speed data transmission. The work can be divided into three parts which deals with major aspects of PMD: characteristics, transmission and compensation. Polarization-mode dispersion (PMD), in single-mode optical fibers, is a phenomenon that a limit the bit-rate-distan...
