The color itself does not affect how light travels through the fiber. The glass inside the. The coloring of optical fibers is a key step in their manufacture, vital for the correct installation and maintenance of networks. This process is carried out following strict international standards that guarantee quality and accuracy in fiber identification. Its purpose is operational consistency. [pdf]
