However traditional dispersion compensator only can compensate the channels which have same dispersion.

Polarization mode dispersion(PMD)in fiber Bragg gratings(FBG) is investigated with the emphasis on the PMD of chirped FBG dispersion compensators.

10 GHz optical pulses generated by a deeply directly modulated laser(DML)enter a LiNbO3 electroopitc phase modulator to enhance the negative chirp and enlarge pulse width,and pass through dispersion compensation fibers(DCF) to compress chirps.

On the basis of the causes of fiber dispersion and its effects on optical transmission systems,this article introduces some dispersion compensation technologies with the focus on the most commonly used dispersion compensation fiber(DCF) technology.

It is difficult to realize in conventional dispersion compensation fiber(DCF).

The tunable dispersion compensator is composed of 2×2 optical switches,dispersion compensating fiber etc.

Theory of three cladding dispersion compensating fiber with negative dispersion slope was analyzed, and the effects of all parameters on the fiber′s characteristics were given.

In this letter,the waveguide structure of Dispersion Compensation Fiber(DCF) is designed and a kind of high-performance DCF fabricated.

Different from the traditional schemes, a new scheme of using None Zero Dispersion Shift Fibre (NZ-DSF) and Dispersion Compensate Fibre (DCF) is proposed to weak the n.

Theoretical analysis and numerical simulation of an all-fiber pulse compressor composed of Dispersion-Compensation Fiber(DCF),Dispersion-Shifted Fiber(DSF) using distributed Raman amplification and Nonlinear Optical Loop Mirror(NOLM) are performed in this paper.

Aiming at two kinds of covert QoS attack faced for optical amplifier,the optimized scheme for WDM system based on dispersion compensation fiber(DCF) is introduced,and the optimum dispersion compensation efficiency and optimum installation positions are obtained.

Utilizing phase modulator and dispersion compensation fiber(DCF) link,a non-return-zero(NRZ) data format is converted to return-zero(RZ) data format with tunable duty ratio.

The dispersion of the next high-nonlinear fiber(HNLF) was compensated by dividing the fiber into small segments equally,inserting segments of dispersion compensation fiber(DCF) at regular intervals,the quasi-phase matching was realized and a gain spectrum that was relatively uniform over a wide spectral range was obtained.
