Home / Can the light emitted by the optical module be seen
Self-loop inspection: The light emitted by the multi-mode fiber optical module is visible light, which can be observed with the naked eye (do not look directly at the light-emitting port). Subsequently, the driver semiconductor laser (LD) or light-emitting diode (LED) emits modulated optical signals at the corresponding rate. An optical module works at the physical layer of the OSI model and is one of the core components in the fiber communication. Its fundamental role is to bridge the gap between electrical equipment and optical fibers.
