Des tentatives ont été faites pour évaluer et étudier les émissions rayonnées des modules à fibres optiques actuellement disponibles sur le marché. Les mesures de l'intensité du champ électrique lointain montrent que l'émission rayonnée présente un pic à une onde harmonique d'ordre élevé de la fréquence d'impulsion fondamentale et atteint un niveau dépassant les valeurs limites des spécifications de bruit CISPR. Les mesures de distribution du champ magnétique proche montrent que la source du bruit d'interférence se situe entre un module de diode électroluminescente (LED) et un pilote de LED. Ces mesures sont comparées à celles de calculs de champ électromagnétique basés sur un circuit équivalent haute fréquence. En conséquence, il a été établi que les effets de pointe des ondes d'impulsion déformées transmises entre un module LED et un pilote de LED et les caractéristiques de rayonnement du circuit émetteur optique agissent comme des facteurs d'augmentation du niveau de rayonnement des fréquences de crête dans l'émission rayonnée. à partir de modules à fibres optiques.

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.
