Fiber optic cable is mainly composed of optical fiber (such as thin hair of glass) and plastic protection sleeve and plastic skin, cable no gold, silver, copper aluminum and other metals, generally no recycling value.Fiber optic cable is a kind of communication line, which is composed of a certain number of optical fibers in a certain way and is covered with a sheath or an outer sheath, to realize the transmission of optical signals.At present, the use of optical cable is more and more extensive, and the use of optical cable accessories and other products are constantly emerging, and the technology related to optical cable is also becoming more and more mature with the wide application of optical fiber.The following Xiaobian to introduce to you the difference between optical cable and optical fiber?Fiber optic cable line fault, characteristics.Let's take a look!

The difference between optical cable and optical fiber: the center of the optical fiber is usually made of glass core, the core is surrounded by a layer of glass envelope lower than the core, so that the light signal into the core through the cladding interface reflection, so that the light signal in the fiber core propagation forward.Because optical fiber itself is very fragile, can not be directly used in the wiring system, so it is usually bundled, outside the protective shell, with a tension resistance, this is the so-called optical cable, optical cable usually contains one or more optical fibers.
