This paper focuses on the modeling of the power budget of remotely pumped long haul optical fiber communication system (OFCS) incorporated with an Erbium doped fiber amplifier in the pre-length (Pre-EDFA) and distributed Raman amplifier (DRA). Signal loss in the post- and pre-length as well as signal gain by the Pre-EDFA and DRA are simulated to determine the maximum achievable transmission distance of a remotely pumped long haul OFCS incorporated with pre-EDFA and DRA. Design parameters of pre-EDFA are optimized using the numerical simulation of EDFA rate equation model in order to optimize the pre-EDFA. DRA mathematical model is solved numerically to analyze the signal propagation characteristics through the pre-length due to DRA. The results obtained frorn the numerical simulation of EDFA and DRA mathematical model are used in the modeling of the power budget of remotely pumped long haul OFCS incorporated with pre-EDFA and DRA. The developed model can be used to design and analyze the performance of a long haul OFCS link and to optimize the system performance. ©Anita Publications. All rights reserved.
