“…Although FBGs have been extensively used for different purposes, utilizing them to improve the optical transmission link performance has revolutionized the telecommunication industry [12][13][14][15][16][17]. Hence, nowadays, researchers are using cascaded FBG structures in optical communication systems to enhance its performance by reducing the spectral width of the laser source, thus reducing the dispersion [18,19]. Therefore, it is noteworthy to study the spectral attributes of a cascaded FBG structure and its impact on the optical communication system.…”

In this paper, an optical communication system constructed with cascaded fiber Bragg gratings or FBGs of varying lengths capable of operating in the C-band is presented. Here, initially, a passive optical device formed with four cascaded FBGs of varying lengths is proposed and analysed. Subsequently, the proposed device is kept in the optical communication system to reduce the spectral widthof the source, thereby enhancing the system's performance. Analytical formulation based on the transfer matrix method (TMM) of an optical device is incorporated. The effect of such a device on the system performance at various operating distances is discussed. Further, the system performance is studied with the apodized FBGs in the passive optical device. At the end, we investigated the effect of incorporating the cascaded FBG structure in the system utilizing four-level pulse amplitude modulation or PAM-4 modulation . As per the simulation results, the proposed device has given a maximum reflectivity of 98.39% and a minimum FWHM of 0.175 nm for uniform FBGs. But with the apodized FBGs, an FWHM of 0.07 nm with a reflectivity of 59.81% has been achieved. Simulation results reveal that the system formed with the proposed device has given better performance up to a distance of 105 km compared to the absence of the device. At the maximum operating distance of the system with apodized FBGs, the Q-factor and bit error rate (BER) are recorded as 6.712 and 9.5321×10-12, respectively. Apart from the Q-factor and BER estimation, eye height is also used to estimate the system performance at various operating distances.

“…The performance of such a system up to a distance of 100 km had been analyzed in terms of bit error rate (BER) and Q-factor. Similarly, the performance of an optical communication system can be improved with a cascaded Tanh apodized FBGs combined with the maximum time-division multiplexing transmission technique is mentioned in [19].…”

The aim of this work is to propose a model for enhancing chromatic dispersion compensation in standard single mode optical fibers (SSMFs). The proposed model consists of a single stage Apodized Uniform Fiber Bragg Gratings (AUFBG) in a post-compensation scheme. It is based on the Maximum Time Division Multiplexing (MTDM) technique. The performance of the proposed model is evaluated through the quality factor (Q-factor) and Bit Error Rate (BER) in four cases, in a comparative study. In case one, the system performance is evaluated without using UFBG. The other cases study the effect of the proposed model with using different connections schemes and the most common apodization functions. For simulation, the proposed model is connected in a 10 Gbps WDM 70 km link under ordinary operating parameters. The simulation and evaluation process is conducted by Optisystem 7.0. In the pre-compensation scheme, the best results are obtained as a maximum Q-factor of 9.2 and a minimum BER of 3.25 × 10–20, using a tanh apodization function. The proposed model realizes an improvement over the related work by at least ~ 68%.
