Optical fiber is a light-transmitting medium made by using total reflection of light in glass or plastic fibers. Because of its large frequency and bandwidth, and low loss, it has become the best tool in modern information transmission. For low-loss fiber, “cage replacement” in a micro space that is only one tenth of the thickness of a hair. By optimizing the doping material and changing the waveguide structure, light scattering is reduced and reflection transmission is smoother.
Let's take a look at this kind of "bullish" fiber called low loss single mode. Its appearance is no different from ordinary optical fiber, and its appearance is protected by a thick plastic sheath, with a single diameter of 250 microns. The "glass fiber" inside the protective cladding, with a light transmission diameter of only 9 micrometers, is the real "protagonist". Optical signals travel fast here with low losses; large capacity travels far.
Optical fiber is like a highway. In a limited space, you need to make the road as wide as possible to allow cars to run more and faster. To improve the optical fiber transmission performance, we can only use our brains in a micro space that is only one tenth as thick as a hair. By using a series of high-tech methods to optimize the doped substances in glass fibers, extract the essence and remove the dross, and at the same time change the waveguide structure of glass fibers, they will work together to build an information highway, which will reduce light scattering and reflect transmission. Smooth.
