2. COURSE DESCRIPTION

The course of Optical Communications has a fundamental importance in the academic preparation of an engineer in Electronics and Telecommunications. In fact, the course will let the students know the most suitable technology in terms of capacity and speed of transmission which has revolutionized the global telecommunications. The course includes the study of passive and active elements of optical communication systems, appiications, network fiber optic submarine cables that land in Ecuador, DWDM technology, and the Ecuador fiber-optic backbone. It includes a technical visit to the facilities of the Salinas Terminal Station of the Pan-American Submarine Cable and to the Control Center of the National Telecommunications Corporation of Ecuador (CNT) Fiber Optic Backbone.
