“…3 c. The results clearly showed the satisfactory performance of the proposed amplifier, which can operate up to -15 dBm without a saturation effect. Finally, the results of our design exhibited a wider gain bandwidth and larger gain level compared with the findings in [9,10,11,12,13,14,15,16,17,18]. Table 1 summarizes the results of the performance evaluation of our work and previous studies.…”

A Widely flatness gain bandwidth with double pass parallel hybrid fiber amplifier is experimentally demonstrated in this study. The proposed design combines serial erbium–Raman fiber amplifier in one branch and Raman fiber amplifier in the second branch. Multiple Raman pump units with a maximum power of 800 mW (250 mW of 1410 nm, 225 mW of 1480 nm, and 325 mW of 1495 nm) are utilized. Pump recycling technique is applied to achieve acceptable pumping efficiency. A maximum flatness gain bandwidth of 80 nm (1525–1605 nm) and average gain level of 22.5 dB are obtained at a small input signal power of -25 dBm and optimum pump power values. By comparison, a wider flatness gain of 90 nm (1520–1610 nm) and average gain level of 11.5 dB are achieved at a large input signal power of -5 dBm.

“…In 1970 and by 1980 the concept was first published for WDM [21] systems and the work was to achieve its laboratory. Two signals only were established at the first of WDM systems [10,22]. The most WDM systems can operate in single-mode fiber, for modern systems about 160 signals can handle and can thus expand to a 100 Gbit/s system over a single fiber, which has a core diameter of 9 µm.…”

“…Input power (dBm), length of optical fiber (km), and coefficient of attenuation (dB/km) were entered. Where each Q-Factor (dB) and was calculated an eye diagram [9][10]. There are several types of FBGs, such as chirped FBGs that provide different wavelengths (frequencies) so that they are very suitable for use as dispersal compensation elements for one wavelength of several waves.…”

Nowadays the technological advancement of the information transmission is developing very rapidly and it becomes necessary to achieve a high speed in the transmission of data as well as higher data rate. Developments in optical communication systems address these needs. However, despite all the features and advantages of optical communication systems, the dispersion is still the main challenges. In this paper and to this end, fiber Bragg grating (FBG) is used in order to overcome the dispersion issue in the wavelength division multiplexing (WDM) transmission system. The WDM transmission system is simulated using the advanced tools of Optisystem 13. The simulation program was used at a speed of 15 Gbits/s with 50Km optical fiber length based on the different input design parameters such as input signal power, optical fiber length and attenuation coefficient. In addition, the output performance parameters are discussed in terms of quality factor (Q-factor) and eye diagram. Moreover, a comparison between the proposed design and previous related works is presented.

“…However, two major limitations still exist, namely, phase mismatch between amplified signals after these two branches due to the long signal propagation in DCF and possible absence of dispersion compensation in EDF. Another DCF fiber is connected serially to the EDFA branch in PHFA to overcome these two limitations [15,16,17]. The PHFA design with multiple Raman pump power units (800 mW of 1480 nm and 300 mW of 1495 nm) was reported by [15].…”

“…The flatness gain bandwidth and the average gain slightly increased to 65 nm and 16 dB, respectively. Thirty-two input channels were examined in the PHFA design under the same parameters presented by [16] and the system showed acceptable amplification performance in terms of dispersion issue and phase matching [17]. Low and limited flatness gain levels were the main degradation products in previous studies.…”
