Percubaan telah dibuat untuk menilai dan menyiasat pelepasan terpancar daripada modul gentian optik yang kini tersedia di pasaran. Pengukuran kekuatan medan elektrik jauh menunjukkan bahawa pelepasan terpancar mempunyai kemuncak pada gelombang harmonik tertib tinggi bagi frekuensi nadi asas dan mencapai tahap yang melebihi nilai pengehadan spesifikasi hingar CISPR. Pengukuran taburan medan magnet berhampiran menunjukkan bahawa punca bunyi gangguan terletak di antara modul diod pemancar cahaya (LED) dan pemacu LED. Pengukuran ini dibandingkan dengan pengiraan medan elektromagnet berdasarkan litar setara frekuensi tinggi. Hasilnya, telah ditetapkan bahawa kedua-dua kesan puncak gelombang nadi cacat yang dihantar antara modul LED dan pemacu LED dan ciri-ciri sinaran litar pemancar optik bertindak sebagai faktor untuk meningkatkan tahap sinaran frekuensi puncak dalam pelepasan terpancar. daripada modul gentian optik.

Abstract: Attempts have been made to evaluate and investigate the radiated emissions from fiber optical modules that are currently available in the market. Far electric field strength measurements show that the radiated emission has a peak at a high-order harmonic wave of the fundamental pulse frequency and reaches a level exceeding the limiting values of the CISPR noise specifications. Near magnetic field distribution measurements show that the source of the interference noise lies between a light emitting diode (LED) module and an LED driver. These measurements are compared with those of electromagnetic field calculations based on a high-frequency equivalent circuit. As a result, it was established that both the peaking effects of deformed pulse waves transmitted between an LED module and an LED driver and the radiation characteristics of the optical transmitter circuit act as factors for increasing the radiation level of the peak frequencies in the radiated emission from fiber optical modules.
