Practical knowledge of fiber optic cables

Optics ADSS Fiber Optic Cable

adss cable Optical fiber is similar to coaxial cable, except it has no mesh-like light-emitting layer. At the center is a glass core through which light travels. In multimode optical fiber, the diameter of the core is 15mm~50mm, which is roughly the same thickness as a human hair. The diameter of the single-mode optical fiber core is 8mm~10mm. A glass envelope on the outside of the core is lower than the core to keep the fiber inside the core.  Optical fibers are usually bundled into bundles and protected by a casing on the outside. The fiber core is made of quartz glass, which is usually an arc-shaped circular concentric cylinder. Its texture is brittle and easy to break, so it needs an external protective layer. Its structure is shown in Figure 1.  

 cable adss Optical fibers on land are usually buried 1 meter underground and are sometimes damaged by small animals underground. Closer to shore, transoceanic fiber optic casings are buried in trenches. In deep water, they are on the bottom and are at high risk of being bitten by fish or hit by fishing boats.
