1. The difference between the concept of optical cable and optical fiber:
The full name of the optical fiber is called the optical fiber, which is drawn from pure quartz with a special process into a glass tube thinner than a human hair with a few media in the middle. Its texture is brittle and easy to break, so an extra layer of protection is required.
Optical cables are mainly composed of optical fibers, plastic protective sleeves and plastic sheaths. The protective structure of the outer layer can prevent the damage of the optical fiber from the surrounding environment.
Fiber optic cables contain optical fibers and are part of a fiber optic cable. Optical fiber is the glass fiber in the optical cable, but the abbreviation of the two is often not strictly distinguished in engineering applications.
2. The distinction between optical cable and optical fiber structure:
Optical fiber is mainly divided into two categories, one is graded optical fiber, and the other is stepped optical fiber. The refractive index of the former is graded, while the refractive index of the latter is abrupt.
Optical cables are mainly composed of optical fibers, plastic protective sleeves and plastic sheaths. There are no metals such as gold, silver, copper and aluminum in the optical cables, and generally they have no recycling value.
3. The difference between the propagation efficiency of optical cable and optical fiber:
Optical fiber, scientists have created "internal adhesion method", "MCVD method", "VAD method" to make ultra-high-purity quartz glass, and the efficiency of light transmission of specially-made optical fibers has been significantly improved.
Optical cable, communication optical cable is a kind of communication line in which a certain number of optical fibers form a cable core according to a certain method, which is covered with a sheath, and some are also covered with an outer sheath to realize the transmission of optical signals.
