Abstract

This study analyzes the application of Wavelength Division Multiplexing (WDM) in fiber optic networks which aims to find the wavelength, WDM optical spectrum and modes, as well as the CPR estimated phase and modes. In this study WDM allows the simultaneous transmission of different data streams through a single optical fiber, using different wavelengths. This research was conducted using the python OptiCommPy module. This module is used to perform modeling of complex optical fiber transmission systems by considering the various parameters and disturbances involved in optical transmission. The results obtained from this study are that WDM networks can use full or limited wavelength conversion, depending on the wavelength conversion capability of each network node. Whereas multifiber networks use fiber pools between network nodes, and multifiber WDM networks can be implemented without or with full wavelength conversion. This research can be a guide for designing coherent electromagnetic waves in WDM transmissions using the OptiCommPy python module.

Abstract

The reason for conducting research is based on several problems in the form of teaching activities whose center is still on the teacher (teacher centered), on the other hand the students' learning outcomes are still low and the teaching process has not been able to fully improve student outcomes in their learning. The aim of the research is to find out the effect of Couple Card media on Elementary School Students’ Science Learning Outcomes in Class IV MIN 8 Medan City. The research method used was in the form of an experiment through a quasi-experimental design in the form of a nonequivalent control group, which acted as research subjects, consisting of 40 students of class IV. In analyzing the data, the researcher conducted a normality test accompanied by the Wilcoxon test due to not normally data distribution. Based on the Wilcoxon signed rank results, it can be seen that Asymp.Sig.(2-tailed) has a value of 0.001. Because the value of 0.000 is smaller than 0.05 (0.000 < 0.05) it is understood that there are differences in learning outcomes with these differences being significant both in the pretest and post-test when learning is not carried out using couple card media. Through the use of media in the form of couple cards it is known that there is an influence on the learning outcomes passed by students so that it was concluded that the media in the form of couple cards provided an increase in student results in their learning.
