The interference factors of optical fiber transmission signal mainly include the following:
Defects of the fiber itself: There may be some defects in the fiber itself, such as microbends,lorawan wireless gateway changes in the core diameter, uneven refractive index of the fiber, etc. These defects will cause the scattering and attenuation of the optical signal, thereby affecting the transmission performance of the fiber.
Quality of fiber optic connection: The quality of fiber optic connection also has a great influence on the transmission of optical signals. If the connection is poor or the contact is poor, it will cause the reflection and scattering of the optical signal, thus affecting the transmission quality of the optical signal.
Performance of light source and receiver: The light source and receiver are two important components in the optical fiber transmission system, and their performance serial to ethernet adaptor will affect the transmission quality of the optical signal. If the power of the light source is insufficient or the sensitivity of the receiver is insufficient, the attenuation of the optical signal will be caused, thereby affecting the transmission quality.
Interference from external light sources: The optical fiber transmission system is easily interfered by external light sources, such as sunlight, lights, lasers, TV signals, etc. These interferences will have a great impact on the transmission quality of optical signals. Electromagnetic interference: Although the optical fiber transmission system itself is not susceptible to electromagnetic interference, the electronic equipment (such as amplifiers, modulators, demodulators, etc.) in the optical fiber transmission system is prone to electromagnetic interference, which affects the transmission quality of optical signals
