Monitoring And Suppression Of Chromatic Dispersion Using Electronic Equalizer In Fiber Optic Communication Link
Dispersion phenomenon limits the performance of an optical fiber communication link very often, which causes the optical pulse to broaden as they travel through the fiber. These expanded pulses may overlap with each other at the output giving rise to Intersymbolic Interference (ISI). Dispersion posses a great hindrance to achieve high data rates and longer links in fiber optic communication sys...
متن کاملSimultaneous 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...

هدف اصلی این تحقیق مقایسه و تمایز بین روشها و استراتژیهای خاص برای درک مطلب بهتر در زبان مادری و زبان دوم بوده است. در قدم اول میزان توانایی افراد در درک مطلب فارسی و انگلیسی اندازه گیری و سپس رده بندی شد. همچنین از دانش آموزان خواسته شد که در مورد روشها و استراتژیهایی که برای درک مطلب بهتر به کار برده بودند توضیح دهند. نتیجه این مرحله از تحقیق نشان داد که دانشجویان برای درک مطلب مطلوب در زبان ...
15 صفحه اولMonitoring Nonlinear Profiles Using Wavelets
In many manufacturing processes, the quality of a product is characterized by a non-linear relationship between a dependent variable and one or more independent variables. Using nonlinear regression for monitoring nonlinear profiles have been proposed in the literature of profile monitoring which is faced with two problems 1) the distribution of regression coefficients in small samples is unkno...
متن کاملChromatic Dispersion Monitoring of Optical OFDM Signals in Flexible Optical Networks
A chromatic dispersion monitoring scheme for flexible optical OFDM networks is presented. Coded label subcarriers are added to the signal spectrum and dispersion monitoring is performed via direct detection, followed by electronic correlation procedures.
