Abstract:

Dense Wavelength Division Multiplexing (DWDM)is a technique that has been developed to improve the channel range and bandwidth of optical fibre transmission systems. Multiple information channels of varying wavelengths are sent on a single fibre The phenomenon of an input signal spreading out as it flows down the fibre is referred to as optical fibre dispersion. Chromatic, modal and polarisation mode dispersion are all examples of dispersion in fibre optic cable. To compensate for such dispersion, this paper introduces two techniques: Dispersion Compensation Fibre (DCF) and fibre Bragg Grating

Abstract:

Since the data traffic is increasing day by day so there is a need of high capacity long distance optical links.As the data transmission increases over a long distance,signal gets deteriorated.This is because of the pulse widening known as dispersion and it should be compensated for better results.Different compensation techniques are available like FBG, EDC and DCF. Hence, in this paper we have used DCF as dispersion compensator at a bit rate of 100Gbps over a distance of 120km.ThreeDCF schemes i.e. pre,post and symmetric are proposed and investigated at different input power levels (1-10dBm)

Abstract:

In case of long distance communication, high bit rate and large bandwidth are always the primary requirements. The major limiting factor i.e. Attenuation can be reduced by using optical amplifier. But still one more limiting factor is there, which is known as Dispersion, which degrades the quality of optical communication. Hence,in this present investigation, Fiber-optic scattering or Dispersion and its impact on optical transmission are inspected. The most frequently utilized,Fiber Bragg Grating (FBG) method is examined in this article. Three techniques (pre-compensation, post-compensation an

Abstract:

A polynomial nonlinear filter (PNLF)-based electrical dispersion pre-compensation (pre-EDC) scheme assisted with Gerchberg–Saxton (GS) algorithm is proposed to compensate the chromatic dispersion (CD) for intensity-modulation and direct-detection (IM/DD) optical transmission systems, where PNLF is utilized to fit the nonlinear transfer function of the iterative GS algorithm-based pre-EDC scheme to realize a low-complexity non-iterative CD pre-compensation. The capability of PNLF to fit the nonlinear iterative process enables the PNLF-based pre-EDC scheme to compensate for CD-induced linear dis

Abstract:

To address chromatic dispersion (CD) and nonlinear impairments in coherent optical four-level pulse amplitude modulation (PAM4) systems, we propose a magnitude-assisted decision feedback equalizer (MA-DFE). The proposed scheme utilizes signal amplitude information to construct the error function, which is robust to carrier phase noise. Therefore, no additional carrier phase recovery operation is required during digital signal processing (DSP). Under conditions without CD pre-compensation, MA-DFE achieves 80 Gb/s single-wavelength transmission over a 25 km standard single-mode fiber (SSMF) in t

AbstractIn this paper, the major aim is to enhance the bandwidth and therefore increase the capacity of the optical fibre communication system by reducing the dispersion in the fibre. Dispersion compensation is necessary to reduce losses and cost of the system. In this paper, we are basically focusing on reducing or decreasing chromatic dispersion. Chromatic dispersion is a type of dispersion in which pulse broadening occurs due to delay in different spectral components. We here make use of dispersion compensated fibre (DCF) for reducing the dispersion in the WDM system. Here, we basically use

Chromatic dispersion is one of the key limitations to increasing the transmission distance-rate product for short-reach communication systems relying on intensity modulation and direct detection. The available optical dispersion-compensation techniques have lost favor due to their high impact on the link loss budget. Alternative digital techniques are commonly power-hungry and introduce latency. In this work, we compare different digital, optical and joint hybrid approaches to provide equalization and dispersion compensation for short-reach optical transmission links.

Abstract Chromatic dispersion and nonlinear impairments pose challenges in high-capacity optical transmission systems, leading to signal distortions, channel interference and diminished the transmission performances.
