Original Abstract

Currently used Passive optical networks (PON) are based on bidirectional transmission. The wavelength for downstream traffic is 1490 nm and the wavelength for upstream traffic is 1310 nm. Optical fiber amplifiers (OFA) can amplify wavelength around 1550 nm. Hence, Semiconductor optical amplifiers (SOA) have been chosen for the simulation. SOAs amplify in both directions, but the spectral width is around 200 nm. Therefore, two different amplifiers have to be used for each direction. The best position of amplifiers in the net-work has been investigated, because of the saturation at high output power. A bandpass filter placed behind amplifiers has been used to improve the output signal.
