glasvezelkern

Glasvezelkern refers to the central part of an optical fiber, which is responsible for transmitting light signals. It is typically made of highly pure glass, most commonly silica, and has a higher refractive index than the surrounding cladding. This difference in refractive indices is crucial for the principle of total internal reflection, which guides the light along the fiber. The diameter of the glass fiber core can vary, ranging from a few micrometers for single-mode fibers to tens or hundreds of micrometers for multi-mode fibers. The purity of the glass is paramount to minimize signal loss, also known as attenuation, as impurities can scatter or absorb light. The manufacturing process for glass fiber cores involves precise control over the composition and dimensions to ensure optimal optical performance and reliable data transmission over long distances.
