Abstract: First a simple all-optical logic device, called Mach Zhender Inferometer is composed by using a Semiconductor Optical Amplifier (SOA) and an optical coupler. This device is used for generating the logical functions (AND, XOR) and a multiplexer and an Encoder are obtained using this device in Optical Tree Architecture. A fiber communication system is employed using Giga Ethernet Passive Optical Network (GE-PON) architecture. In this architecture an optical fiber is employed directly from a central office to the home. 1: 8 splitters are used as a PON element which establishes communication between central offices to different users. In this chapter GEPON architecture has investigated for different lengths from a central office to the PON in the terms of BER. For 10 Gbit/s systems the plots between the BER and transmission distance is plotted and it is seen that as the distance increases beyond the 15 Km the BER is increased very sharply.
