Supervisor:

Department of Electromagnetic Field

Synopsis:

The main aim of this subject is to introduce with measurement techniques and measurement methods for optical fibers. The subject includes methodologies for measurement of constructive and transition parameters of optical communication systems such as numerical aperture, attenuation, dispersion etc. The measurements of principal characteristics of active and passive elements of optical systems are involved as well.

Requirements:

An active attendance of laboratory exercises together with elaborated measurements has to be fulfilled to reach the ungraded assessment. http://moodle.kme.fel.cvut.cz
