Design of Data Networks

• 26 hrs lectures
• 26 hrs pc labs

Upon completion of the course the student will have an overview of the types and topology of the networks, about the transmission paths of coaxial cables, optical fibers, structured cabling. The student will be able to create project documentation in the design of data networks using AutoCAD Electrical.

The goal of the subject is to teach students to have an overview about the types and network topologies, transmission paths type coaxial cables, optical fibers, structured cabling and teach them create a projected documentation at design of the data network using AutoCAD Electrical system.

The subject knowledge on the secondary school level is required.
