Scientific experiment measurement of optical signal characteristics on fiber optic access network prototype for distance learning education purposes

This research developed a fiber access network prototype system to enhance practical learning experiences in the Telecommunications Transmission Laboratory. A requirements analysis was conducted to identify the necessary hardware, followed by system design, including architecture and network topology. The implementation stage involved hardware installation, system configuration, and performance measurement using devices such as optical media converters, optical distribution frames, optical rosettes, and testing tools like an optical light source (OLS) and an optical power meter (OPM). The system utilized single-mode fiber optic cables with a light source wavelength of 1310 nm. The measurement results indicated power losses of 3.62 dB on the first link and 3.68 dB on the second link. The error percentage was attributed to decimal accuracy limitations of the OPM, which have resulted in a system accuracy of 91.25%. The results aligned with expected outcomes for fiber access networks, demonstrating reliable performance for installation and troubleshooting purposes. The minimal error observed did not significantly affect system functionality. This prototype improved student’s skills in configuring and troubleshooting fiber optic networks and is suitable for use in distance learning environments.
