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.

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.

Different Types

In this paper a hybrid amplifier EDFA-RAMAN DWDM transmission system is proposed and demonstrated. A new hybrid two-stage optical fiber amplifier for dense wavelength division multiplexing (DWDM) network is observed. The hybrid amplifier is cascaded erbium- doped fiber amplifiers (EDFA) & Raman amplifier which provide a nearly flat gain over 80 nm. The hybrid amplifier has been modeled using an Optic-System version 14 on a DWDM transmission. In this paper we compare Q-factor at different input power i.e. at 0db and at 10 db. Here two different types of apodized function (Uniform & Gaussian) are selected as fiber Bragg grating parameters and system performance is analyzed. Performance of the system is analyzed by using BER analyzer.

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.

AbstractOptical amplifiers are developed to boost up the performance of the communication systems. Amplifiers such as erbium doped fiber amplifier (EDFA), RAMAN and semiconductor optical amplifier (SOA) are used for this purpose. It is mandatory to use optical amplifiers for signal transmission to long distances. In this paper, the hybrid optical amplifier EDFA-RAMAN-EDFA is proposed to enhance the signal quality received at receiver end and to initiate the efficient transmission of 8 × 10 Gbps transmission speed for wavelength division multiplexed (WDM) system. The proposed mechanism is evaluated with respect to various parameters such as quality factor, eye-height, and bit error rate (BER) and eye diagram considering various values of transmission distance ranging from 100 to 200 km. The analysis shows that the proposed mechanism has better quality factor value and minimum BER value than the traditional approach. Wider eye opening for proposed technique represents that the distortions produced in the system are least.
