Desenvolvimento de um WebLab para estudo e caracterização de sistemas WDM

Abstract

The advent of the Internet and the development of Information and Communication Technologies (ICT s)generated new spaces for communication and collaboration between groups of people in geographically distinct regions. The association of Web technology with instrument automation and control by computer has made possible the development of the so called Remote Laboratories or WebLabs - distributed environments that allow to access and control experiments remotely through a network or the Internet in real time and with the sensation of presence. In this work, a WebLab was developed for the study and caracterization of a WDM (Wave Division Multiplexing) system, aiming to support and complement activities in faceto-face and distance courses on Optical Communications. Drivers and graphic user interfaces (GUI s) were developed with the software LabVIEW for control and data acquisition of instruments used in a remote experiment to measure the basic features of a WDM system. An application was also developed with the software VPI for the numerical simulation of Bit Error Rate (BER) measurements. This work is part of the activities related to the participation of the Mackenzie Photonics Laboratory in the KyaTera Project of FAPESP s TIDIA Program.
