Erbium doped fiber amplifiers (EDFA) are most commonly used in optical networks for the most assorted applications. The fast power transient effect of the cascaded erbium-doped fiber amplifiers (EDFA) in 45 channels optical ring network is investigated. The power transient effect of EDFA’s are observed when channels are added and dropped. It is shown that, for low channel adding/dropping frequency closed to EDFA transient rate, the transmission performances of the surviving channels are impaired severely. And also ring laser configuration technique has been reported to mitigate the effect of power transients. Optsim simulation was utilized for simulation of the designed DWDM OADM ring network.

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.
