The aim of this work is to present a customized simulation tool for analysis and design of Sagnac loop TOAD's. Basically, we present a fast and versatile tool to emulate the behavior of some key design parameters like those found on non-linear elements, splitters, fiber delay line among others. After proper optimization, we use two different wavelengths for the control and signal hyperbolic secant pulses. Additionally, a band-pass filter is used to guarantee the transmission of signal pulses only. Furthermore, we analyze a bit to bit all optical demultiplexer, where one channel is extracted from a 64 bit frame at 10 Gbps transmission rate, and extend the implementation to work at 100 Gbps. SNR better than 22 dB are achieved with control pulse energy on the order of 200fJ and SOA bias current of 150 mA. A degradation of SNR of about 17 dB was verified for a variation of splitter coupling factor around 20%.
