What's the difference between optical cable and ordinary cable?
Optical fiber and ordinary network cable (mostly twisted pair) refer to the classification of transmission media.
The difference between an Internet cable laser and no Internet cable (What's the matter with no optical signal on the Internet cable?)
The optical fiber is usually a dedicated line, and the cost is relatively high. The network speed is relatively stable. It is suitable for enterprise users or high-end individual users.
Ordinary network cables are generally super five twisted pairs, and the price is relatively low. It is suitable for individual users.
What is the difference between optical fiber and network cable
1. Different materials
Network cable is an indispensable communication connection equipment in LAN connection, which can be divided into twisted pair, coaxial cable and optical cable. Among them, twisted pair is a data transmission line composed of many insulated pairs. For example, the common telephone line in our life is twisted pair, which needs a crystal connector to connect with it.
In fact, optical fiber is what we often call optical fiber, which is a kind of fiber synthesized by light on glass or plastic. It uses the radiation function of plastic to conduct light energy. Generally, the optical fiber will be wrapped in a plastic sheath so that it can be bent without breaking. When the pulse is detected by a light emitting diode or a laser beam, one end of the optical fiber is transmitted from the transmitter to the receiver at the other end.
2. Different transmission speeds
The best class 7 network cable has a transmission frequency of at least 500 MHz, more than twice that of class 6 and super class 6, and a transmission rate of 10 Gbps.
Optical fiber is the fastest transmission medium at present, which can reach 40Gbps-100Gbps. That is to say, it is at least 4 times faster than the network cable transmission
3. Different transmission distances
The transmission distance of the network cable is generally about 80-100m. After more than 100m, the following situations may occur: the signal is unstable, and the network is good and bad when surfing the Internet; The network signal is weak, and the server cannot be connected; There is no signal.
Optical fiber can be divided into multimode optical fiber transceiver and single-mode optical fiber transceiver. Single mode optical fiber transceiver: transmission distance from 20km to 120km; Multimode optical fiber transceiver: transmission distance is 2 km to 5 km.
4. Different costs
Take the same transmission distance of 100 meters as an example for comparison.
What is the difference between optical fiber and network cable
With the development of science and technology, people have higher and higher requirements for network technology. Optical fiber has become the first choice for its advantages of fast transmission speed, security and stability, anti-interference, etc. What is the difference between optical fiber and network cable? Now let's take a look.
1. Different in nature. Optical fiber and network cable are different in nature. Optical fiber is an abstract concept and a transmission rate of dynamic information; The network cable is a medium and a carrier of information transmission.
2. Different functions. The function of optical fiber is to accelerate the transmission of different network information; The network cable is used to connect equipment and improve the efficiency of network information transmission between equipment.
3. They exist in different ways. They existed in different ways before. Optical fibers exist in a virtual way, without physical objects; The network cable is a real cable with specific objects.
