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. |
