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.

Abstract A “black box” model is described for simulating the dynamic forces transmitted to the vehicle hub by a tire running over an obstacle at high speeds. The tire is reduced to a damped one-degree-of-freedom oscillating system. The five parameters required can be obtained from a test at a given speed. The model input is composed of a series of empirical relationships between the obstacle dimensions and the displacement of the oscillating system. These relationships can be derived from a small number of static tests or by means of static models of the tire itself. The model can constitute the first part of a broader model for description of the tire and vehicle suspension system, as well as indicating the influence of tire parameters on dynamic behavior at low and medium frequencies (0–150 Hz).

According to the analytical expression for modal gain of few-mode erbium-doped fiber amplifiers (FM-EDFAs), we propose a method of measuring the absorption loss coefficients of few-mode signals in few-mode erbium-doped fibers (FM-EDFs) by extrapolating the mode–gain curve dependent on the average population inversion. The absorption loss coefficient of an FM-EDF was measured in our experimental platform and used to estimate the effective erbium-ion doping concentration. The feasibility of the extrapolation method was verified by simulation and comparison with the transmission method. Furthermore, the FM-EDFAs with high modal gain and low differential mode gain (DMG) could be optimized by adjusting the FM-EDF’s length and pump power. The analysis process presented here is very useful for the efficient design of FM-EDFAs from a practical point of view.
