Supervisor:

Department of Telecommunications Engineering

Synopsis:

The communication systems are presented in wide area network context. The optical technology in backbone networks is dominant segment of the subject. The transmission and multiplexing of the digital signals are primary part of the subject, the reliability, distribution of clock, management, monitoring and design of the network are secondary part of the subject. The students can use theoretic knowledge in practice while working on the model project of transmission network.

Requirements:

The credit shall require 100% attendance and treatment of laboratory projects and submission of individual project. Evaluation of the exam consists of approximately 20% of the exercises, 30% individual project, 50% for their own exam.
