This piece of research tends to study the behavior of optical systems by doing a simulation on different sketches of optical network designs. The goal is to model a typical fiber network in order to study the transmission penalty under two different data encoding techniques. Optical data transmitted through optical networks undergo multiple impairments contributed to create what’s literally called transmission penalty. Many power margin allocators affect the way optical pulses being transmitted and received, which leads designers to think previously in compensating the losses. The most dominant factors are dispersion, system margin, and encoding techniques. Typical systems have the components of optical devices that can easily simulated using computer softwares in modern studies, in this paper OPTIWAVE system software is the key processor to study optical power in such systems, it’s similar to Simulink library in Matlab except of its concentrated tools in the subject of optics. Encoding techniques such as Non return to zero and Return to zero built devices are the focal point in this experimental paper.
