Abstract –The use of LANs such as campus networks has become the features of the world
that we live-in. In this paper, a detailed studying is presented for designing and analyzing computer
networks for University of Technology campus into 19 buildings.
A Star-Ring topology was proposed and implemented using an Optiysystem software simulation.
This software was used because it can simulate the design system with a much more realistic modeling to
reduce cost and time of practical work and achieve high accuracy of the designed system before
implementation. All the data used to build this optical LAN are in accordance with real existing data.
The results appear with the range, the qualification depends on the result of design simulation for
good quality result and which are targeted to all design.
