“…This may occur even when the optical signal with different frequencies travels through the same light path. However, the impact of the material dispersion can be minimized by using a WDM transmitter with a narrow wavelength spectrum [44]. This enables the wavelength components that are present within the narrow band.…”

Fiber optic communication system offers high-speed, long-distance connectivity and integrates with effective data transmission for modern world applications. The primary challenges in optical communication lead to the detrimental impact of dispersion, which introduces more signal distortion and lowers the quality of data transmission. This research aim is to enhance the performance and reliability of the optical system design by addressing dispersion challenges. This review explores the fundamental analysis of dispersion, such as chromatic, polarization mode, and modal dispersion, and the factors that influence the presence of dispersion characteristics. This research also provides a detailed analysis of dispersion compensation techniques and their necessity for maintaining the integrity of optical communication. Furthermore, the proposed review analyses the passive and active compensation techniques and highlights their significance and limitations. Active dispersion compensation, such as dispersion compensating modules and Digital signal processing methods, are investigated for dynamic optical networks and their adaptability. However, the passive dispersion compensation techniques, such as fiber Bragg gratings and dispersion-compensating fibers, are examined in detail, listing their ability for dispersion mitigation effects. Finally, this comprehensive review provides key insights into the developments and prospects in dispersion compensation techniques

“…It becomes elevated in the DWDM technique by introducing cross-talk between consecutive channels [4]. For dispersion compensation, dispersion compensating fibre (DCF) is one of the efficient techniques, offering uniform dispersion compensation to multiple spectral components and upgradability to already installed links [5,6]. However, in addition to dispersion compensation, data communication development demands throughput increment in DWDM networks [7], for which multiple bands use or band swapping becomes an admirable approach.…”

A 100 km long dense wavelength division multiplexed optical network design with a capacity of 1.28 Tbps is proposed in this paper. The novelty of this work is the use of a dispersion compensating fibre as a Raman amplifier in the S-band for a high-capacity dense wavelength division multiplexing network. The transmission is accomplished auspiciously in the wavelength range from 196 THz to 202. 35THz. The coupling of a Raman amplifier made the realisation of the S-band possible in the network, as the erbium-doped fibre amplifier is competent for amplification in C-and L-bands only. Further, a pump coupler is used for multiple pumping to enlarge the gain spectrum for a high-capacity optical network. The performance analysis of the network is carried out systematically in terms of bit error rate (BER), eye diagram, Q-factor, and optical signal to noise ratio (OSNR). The results demonstrate that the proposed set-up shows adequately low BER, sufficient Q-factor values, wide eye-opening, and commendable OSNR for all receiving channels.

“…To overcome dispersion issue, the most efficient technique that is Dispersion Compensation Fiber (DCF) is introduced having negative dispersion coefficient to compensate the effect of positive dispersion in an optical fiber communication link [9]. However, DCF technique increases insignificant nonlinear effects but it is low cost, simplicity, highly reliable and easy to upgrade of already installed links of single mode fiber (SMF) in an optical network [10]- [16].…”

In this paper, a single channel optical system is proposed with dispersion compensation fiber techniques. Dispersion compensation method restricts the pulse broadening consequence of transmitted pulse in optical systems. To overcome dispersion trouble; dispersion compensation scheme modeled for investigate the performance of optical system. The proposed model is designed for 10Gbps with nonreturn-to-zero (NRZ) modulation format with erbium doped fiber amplifier (EDFA) over a length of 15km single mode fiber (SMF) and 3km dispersion compensation fiber (DCF). The performance of designed model is analyzed in terms of output power (dBm), gain (dB), noise figure (dB), Q-factor, BER and Eye-diagrams by varying the fiber length (km), input power (dBm) and attenuation constant (dB/km). The simulation is carried out in Opti-System7.0 simulator.
