Performance Improvement by Pre-Amplifying with Erbium, Ytterbium Doped Devices Link Extenders of Fiber to the Home

This paper analyzes the performance of hybrid gigabit passive optical network (GPON) and wireless communication (FSO) system using EDFA and EYDWA as pre-amplification configuration to compensate the losses due to the fiber cable and the free space channel for 2.5 Gb/s of data. The performance for both amplifiers has been compared on the basis of distance, FSO range and number of users, however the results of simulation show enhancement offered by EYDWA as compared as EDFA amplifier. This amplifier was able to reach transmission distance over 245 Km optical fiber and 1Km range FSO with best BER value around 10-9 and good eye diagram. Whereas, the fiber distance has been limited to 64 Km by using EDFA amplifier.
