What is the fastest transmission rate in the computer network?
This article will explain in detail what is the fastest transmission rate in the computer network. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.
Among the transmission media commonly used in computer networks, the fastest transmission rate is "optical fiber". The commonly used network transmission media are twisted pair, coaxial cable and optical fiber, and the transmission rate from fast to slow is optical fiber, coaxial cable and twisted pair. Optical fiber has the characteristics of unrestricted bandwidth, which is not affected by external electromagnetic fields, and can realize 10 gigabits per second data transmission.

The network transmission medium is the physical path between the sender and the receiver in the network, which has a certain impact on the data communication of the network. The commonly used network transmission media are twisted pair, coaxial cable and optical fiber, and the transmission rate from fast to slow is optical fiber, coaxial cable and twisted pair.
Optical fiber, also known as optical cable or optical fiber, is composed of optical fiber core, glass mesh layer and shell that can absorb light. It is a small and flexible transmission medium composed of a group of optical fibers to propagate light beams. According to the principle of optics, the light beam is generated by the optical transmitter, the electrical signal is changed into the optical signal, and then the optical signal is introduced into the optical fiber. At the other end, the optical signal transmitted from the optical fiber is received by the optical receiver, and it is converted into an electrical signal, which is decoded and then processed. Compared with other transmission media, optical fiber has good electromagnetic insulation, small signal attenuation, wide frequency band, fast transmission speed and large transmission distance. It is mainly used for backbone network connection which requires long transmission distance and special wiring conditions. Not affected by the external electromagnetic field, unlimited bandwidth and other characteristics, can achieve 10 gigabits per second data transmission, small size, light weight, data transmission can be hundreds of kilometers, but the price is expensive.
It is divided into single-mode fiber and multimode fiber:
Single-mode fiber: using laser as light source, only one optical path, long transmission distance, 20-120km.
Multimode fiber: emitted by diodes, low speed and short distance, within 2 km.
The optical fiber needs to be connected by St head connector.
