In this paper cross-phase modulation (XPM) and its impact on multispan NRZ-modulated wavelength division multiplexing (WDM) systems is examined. An analytical model is presented to assess the signal degradation. The impairments due to XPM are related to a Q-factor. The presented formulas are examined for different dispersion compensation schemes and also mixed-fiber systems. The analytical mode...

Since a dispersion interferometer is insensitive to mechanical vibrations, a vibration compensation system is not necessary. The CO2 laser dispersion interferometer with phase modulations on the Large Helical Device utilizes the new phase extraction method which uses modulation amplitudes and can improve a disadvantage of the original dispersion interferometer: measurement errors caused by vari...

We investigate dual concentric core and microstructure fiber geometries for dispersion compensation. Dispersion values as large as -59 000 ps/(nm km) are achieved, over a broad wavelength range with full width at half maximum exceeding 100 nm. The trade-off between large dispersion and mode area is studied. Geometries with an effective mode area of 30 microm2 and dispersion -19 000 ps/(nm km) a...

This paper review of the chromatic dispersion compensation in optical fiber communication system. In optical communication system to compensate dispersion Fiber Bragg grating (FBG) is one amongst the applicable and necessary components. During this the appliance of chirped FBG was studied as a dispersion compensator in optical communication systems. This paper studied the various types of simul...

We simulate a 2000-km 10-Gb/s single-channel NRZ system with different polarization mode dispersion compensation (PMDC) techniques and compare the effectiveness of compensation with linear and nonlinear signal propagation. Significant differences are found between the results of PMDC with and without nonlinearity for all the compensation techniques that are examined. An analysis of PMDC based o...

The wavelength demultiplexer, using cascaded optical fiber gratings and circulators, was proposed and developed for application to optically amplified wavelength-division multiplexing (WDM) submarine cable systems with 100GHz channel spacing. Our proposed demultiplexer cannot only achieve high wavelength selectivity, small excess loss and effective allocation of dispersion compensation fibers f...
