“…Similar work has been performed before with other types of optical amplifiers. 10 Our research is focused on the limitations and advantages of using high order digital modulation formats for long haul optical signal transmission using the simulation tool OptSim utilizing the frequency domain method. Non-returned to zero (NRZ) on-off keying (OOK) is one of the most popular modulation methods for long-distance transmission because of its simplicity in design.…”

Here, the amplification performance of distributed Raman amplifier in a dense wavelength division multiplexed (DWDM) system is analyzed. We aim to compare the performance of distributed Raman amplifier using different digital modulation formats accordant with the bit error rate (BER) and Q factor through simulations. The various pumping methods like forward pumping, backward pumping, and bidirectional pumping for different pump powers have been compared by varying the modulation formats.Binary phase shift Keying (BPSK), differential phase shift keying (DPSK), carrier suppressed DPSK (DPSK-CS), and quadrature phase shift keying (QPSK) with RZ and NRZ are analyzed as their spectral efficiency is found to be better than OOK systems. Our simulation results indicate that the bit error rates are much lesser for Raman Amplifier systems with QPSK-NRZ modulation format having SNR improvement of almost 6 dB.

The main goal of designing a multistage fiber amplifier is to achieve higher performance for long-haul optical transmission systems. In this paper, multistage triple-pass (TP) TDFAs are represented. Three types of TP-TDFA are modeled, optimized, and compared in the S-band for next-generation fiber optical communication systems. First, to examine the performance of these 3 types of TP-TDFAs, signal power, pump power, thulium-doped fiber (TDF) length, and thulium ion concentration were optimized in the input signal at the 1469 nm wavelength, which gives the highest gain value in the S-band, respectively. Second, the input signals in the 1444–1499 nm band gap were amplified by using these specified optimized values in all designs. Gain and noise figure values of all three types were obtained and analyzed by plotting separately for easy comparison. At the end of the study, all results were evaluated and all types were compared to determine the best TP-TDFA.
