AbstractIn this work we have investigated semiconductor optical amplifier (SOA), erbium-doped fiber amplifier (EDFA) and RAMAN Amplifier separately under 64 channels WDM system at 10 Gbps data rate. A comparison is made based upon the values of Q- factor, bit error rate (BER), and power received for different values of laser (present at the transmitter) power. The eye diagram for the three optical amplifiers has also been analyzed. Also the performance factors (Q- factor, BER, and power received) are evaluated for different values of fiber length. In general it is observed that with respect to the power received for a particular laser power (at the transmitter) and up to a fiber length of about 120 km Semiconductor optical amplifier (SOA) gives the best result among all the three amplifiers. With respect to the quality (Q) – factor the RAMAN Amplifier gives slightly better result for a given laser power and for a short fiber length (up to a fiber length of 50 km). For long distance (fiber length greater than 160 km) the Q – factor for all the three optical amplifier saturates and become equal. In terms of Bit Error Rate, RAMAN amplifier is best as it gives minimum BER at a given laser power but up to the fiber length of 70 km EDFA provides minimum BER.

AbstractThe aim of this paper is to analyze the performance of RAMAN amplifier (RAMAN), Erbium-doped fiber amplifiers (EDFA) and semiconductor optical amplifier (SOA) amplifiers separately at 10 Gbps data rate for 32-channel WDM system for a fiber length of 40 km to 280 km. Depending upon the results, the performance of the three amplifiers has been compared. It is observed that RAMAN amplifier provides a better result in terms of Q factor up to a fiber distance of approximately 20 km and in terms of bit error rate (BER) up to a distance of approximately 40 km among all the three amplifiers. EDFA starts providing better Q factor after a fiber distance of approximately 20 km and better BER after a fiber distance of approximately 40 km among all the three amplifiers. But power received is minimum in case of RAMAN amplifier. In terms of power received, SOA provides better result up to a fiber distance of approximately 120 km and after that EDFA provides a better result in terms of power received among all the three amplifiers. All these parameters (Q factor, BER and power received) are also analyzed for different values of laser power. Finally, the eye diagram has also been analyzed.

AbstractThe objective of current work is to design and analyzed 96×10 Gbps DWDM system taking EDFA, SOA, and RAMAN amplifier as an inline amplifiers up to a fiber length of 300 km. The performance of EDFA, SOA, and RAMAN amplifier is measured on the basis of power received, Q-factor, probability of error and BER for various values of fiber distance. In this paper it has been proved that for 96 channels DWDM system at 10 Gbps bit rate, EDFA reveals superior performance as far as the amount of power received is concerned. The value of quality factor (Q-factor) for RAMAN amplifier is almost identical to that of the Q-factor for EDFA and is higher than the Q-factor for SOA till a fiber length of roughly 80 km thereafter SOA reveals somewhat better Q-factor than EDFA and RAMAN amplifier. As far as BER is concerned EDFA and RAMAN amplifier show roughly identical and somewhat lower BER than SOA till a fiber length of roughly 80 km, afterwards SOA reveal somewhat lesser BER till the fiber length of 210 km. In relation to the probability of error P(E), It is analyzed that P(E) remains more or less same for the entire set of optical amplifiers(OAs) but beyond the fiber length of 240 km EDFA shows somewhat lower P(E) than the other two OAs. At the end the Eye diagrams for the three OAs are also figure out.

The Impact

A simple analytical expression is derived to calculate the Bit-Error Rate in lightwave systems with optical amplifiers. According to this expression the Bit-Error Rate can be estimated by the signal power and the ASE spectrum density before the receiver. The theoretical calculation agrees with the experiment very well, so it can provide a method to judge the quality of the optical channel in the optical communication system with optical amplifiers. Futhermore, the impact of the ASE noise on the receiver sensitivity is discussed. It is important to select proper receivers in practical systems.

AbstractIn the evolvement of current passive optical networks (PONs), there is ever increasing bandwidth demand due to dynamic service requirements. This introduces challenge for the choice of multiplexing technique and physical layer bounds like fiber length, data rate, and number of users are critical over a suitable architecture. In this article, hybrid wave division multiplexing-time division multiplexing PON is analyzed using variable length of fiber with data rates up to 40 Gbps over a maximum of 128 end users. Comparative study using different frequency spacing’s has shown that it has negligible effect on the Q-factor performance parameter. Further in the work, variable data rates required for different services is successfully transmitted up to 30 km to 128 number of users for an acceptable level of bit error rate.

Abstract In this paper, we have simulated an optical 32 channel WDM system with 10 Gbps data rate for various hybrid amplifiers at varying lengths. Stand-alone EDFA gives better performance than other individual amplifiers but when hybrid with Raman amplifier, the performance of the WDM system is enhanced. A lot of researchers are working on the hybrid amplifiers like EDFA and Raman. In this research paper we have also included latest amplifier such as Ytterbium and Praseodymium amplifiers and the performance of the various hybrid combinations is compared. So, different hybrid amplifiers such as Raman-EDFA, EDFA-Yb, Raman-Yb, EDFA-Pr and Raman-Pr have been analyzed for performance parameters like quality factor, bit error rate, eye height and channel power. The analysis shows that EDFA-Pr has maximum Q-factor of 15.4883 at 80 km. EDFA-Pr has a maximum eye opening of 0.00534 at 80 km of length but at 120 km transmission distance EDFA-Yb shows maximum eye opening of 0.00154. Below 100 km of transmission distance, EDFA-Pr shows minimum BER value ranging from 10–54 to 10–20 but as the length is increased above 100 km EDFA-Yb shows better performance with values ranging from 10–16 to 10–09.

AbstractThis paper aims to analyze the performance of FBG 60 channel wavelength-division multiplexing system using different optical amplifiers namely RAMAN, erbium-doped fiber amplifier (EDFA) and semiconductor optical amplifier (SOA) separately at 10 Gbps data rate up to a fiber length of 280 km. Based upon the results, the performance of the three amplifiers has been compared on the basis of multiple performance parameters. It is seen that EDFA simulates good results in terms of bit error rate (BER) up to a fiber distance of approximately 80 km and Q factor up to a distance of approximately 90 km among all the three amplifiers. However, power received is least in EDFA. RAMAN amplifier provides a better Q factor after the fiber distance of approximately 90 km and a better BER after the fiber distance of approximately 80 km compared to the other three amplifiers. SOA shows better results in terms of power received up to a fiber distance of approximately 100 km. RAMAN amplifier provides better output power after a distance of 100 km. Eye diagrams and power spectrums of the network with different optical amplifiers has also been analyzed.
