Answer the doubts first, which is faster, optical fiber or optical cable? The answer is just as fast.

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 optical signal transmission. That is: a cable formed by an optical fiber (optical transmission carrier) through a certain process. The basic structure of optical cable is generally composed of cable core, reinforcing steel wire, filler and sheath, etc. In addition, there are waterproof layer, buffer layer, insulated metal wire and other components as needed.

In fact, the two are not on the same level. Optical cables are responsible for large-scale ultra-distance communication, optical fibers are responsible for accessing users, optical fibers need to be connected to optical cables to access the Internet, and optical fibers and cables are together.

We can understand it as the same networking method:

1. Optical cable integrated circuits are produced by the company and are responsible for the communication of the whole city, and optical fibers are only the king of the home network

2. Optical fiber is the abbreviation of optical fiber, which is a fiber made of glass or plastic, which can be used as a light transmission tool. The transmission principle is 'total reflection of light'. Kao Kun, the former president of the Chinese University of Hong Kong, and George A. Hockham first proposed the idea that optical fibers can be used for communication transmission, for which Kao won the 2009 Nobel Prize in Physics. The tiny fiber is encased in a plastic jacket that allows it to bend without breaking. Typically, a transmitter at one end of an optical fiber uses a light emitting diode (LED) or a laser to transmit light pulses to the fiber, and a receiver at the other end of the fiber detects the pulses using a photosensitive element.

3. Optical fiber cable is manufactured to meet optical, mechanical or environmental performance specifications. It uses one or more optical fibers placed in a sheath as a transmission medium and can be used alone or in groups. communication cable assemblies. Optical cables are mainly composed of optical fibers (glass filaments as thin as hair), plastic protective sleeves and plastic outer skins. There are no metals such as gold, silver, copper and aluminum in the optical cables, and generally have no recycling value.
