1. The concept and relationship between optical cable and optical fiber:

1. Optical fiber: shorthand for optical fiber. It is drawn from pure quartz with a special process into a glass tube thinner than a hair with several media in the middle. It is a kind of fiber made of glass or plastic based on the principle of total reflection of light. Achieved light transmission tool. Its brittle texture necessitates an extra layer of protection.

2. Optical cable: It is mainly composed of optical fiber (glass filament as thin as hair), plastic protective sleeve and plastic sheath. There is no metal such as gold, silver, copper and aluminum in the optical cable, and generally has no recycling value. An optical cable is a cable core composed of a certain number of optical fibers in a certain way, covered with a sheath, and some are also covered with an outer sheath. The protective structure of the outer layer can prevent the surrounding environment from harming the optical fiber. It is a communication line used to realize optical signal transmission. That is: the optical cable is a cable formed by an optical fiber (optical transmission carrier) through a certain process.

3. The relationship between the two:

Broadly speaking, optical fiber is an optical cable, which is a transmission medium. But strictly speaking, the two are not the same product. A fiber optic cable contains optical fibers and is 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.

Second, the difference between optical cable and optical fiber:

1. The difference between composition structure and use:

(1) In layman's terms, each individual core is called an optical fiber, and the combination of multi-core optical fibers into a cable is called an optical cable.

(2) The optical cable is mainly composed of optical fiber (glass filament as thin as hair), plastic protective sleeve and plastic sheath. An optical cable is a communication line in which a certain number of optical fibers form a cable core in a certain way, and is covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission.

That is: a cable formed by an optical fiber (optical transmission carrier) through a certain process.

(3) The basic structure of an optical cable is generally composed of several parts such as a cable core, a reinforced steel wire, a filler and a sheath, and other components such as a waterproof layer, a buffer layer, and an insulated metal wire as required.

2. The difference in propagation efficiency between optical cable and optical fiber:

For optical fiber, scientists have created ultra-high-purity quartz glass by creating "internal attachment method", "MCVD method" and "VAD method".

Optical cable, communication optical cable is a communication line in which a certain number of optical fibers form a cable core in a certain way, and is covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission.
