Over the years, optical communication systems have been seen as one of the attractive solutions to the increasing high data rate in telecommunication systems. There also has been a tremendous increase in usage of transferring information like Internet and multimedia applications. The scientific research in optic and/or photonic area is in continuous evolution. While students formation in this field is, in many cases, insufficient and, often, too much theorist. The purpose of my thesis is to allow to approach, particularly Telecommunications Engineering students, to the optic communications world. First of all, already from the simple accademic courses, it can be a launch pad to create more and more people interest in this field. For a long time term, there will be a great number of potential researchers in order to increase the technological progress. This can now seem only a banality. However, during my university studies, I observed that the practical study is becoming very important to learn targets, obviously accompanied by good theoretical bases. Overall, this thesis illustrates a student lab practice with a previous theoretical explanation. Students job is based on the one system of measure of Syncronous Digital Hierarchy (SDH) pseudo-real and high speed traffic. This traffic is produced to a high-performance and expesive device. The device made up of Tecktronix, labeled with ST2400A. In reality, it is an electric/optic transceiver of traffic SDH at 2.5 Gb/s. The receiver is able to monitor diretctly system performances. Through this system of measures BER, eye-diagram, jitter, control of bias, to different distance (25 and 50 km) are calculated and other factors typical of the optic communications.
