Speaking of fiber optics, some people will feel no stranger, but to talk about the layout of fiber, many people still do not understand, today, Inline Closure manufacturers to popularize the layout of fiber optics:

The main body of the core material is silica, which contains a very small amount of other materials, such as cerium oxide, phosphorus pentoxide and the like. A noisy influence is the refractive index of the progressive data. The core diameter is about 5~~75μm.

The surface of the fiber has a cladding layer, and the cladding layer has one layer, two layers (inner cladding layer, outer cladding layer) or multiple layers (called multi-layer layout), but the total diameter is above 100~200 μm. The data of the cladding is the same as pure silica, and there is also a very small amount of boron trioxide. The latest method is to do a small amount of fluorine, which is a very small amount of silicon tetrafluoride in pure silica. A noisy influence is the refractive index of the light of the low data. Thus, the refractive index of the fiber core is slightly higher than the refractive index of the cladding. The difference between the two seats ensures that the light tension is limited to the transmission in the core.

The surface of the cladding is also coated with a coating of silicon copper or acrylate. The effect of the coating is to shield the fiber from external damage and increase the mechanical strength of the fiber.

The outermost layer of the fiber is a jacket layer, which is a plastic tube that also acts as a shield. The divergent color plastic tube can also be used to distinguish the various fibers.
