What are the benefits of using fiber optic cables in a network

The data transfer speed is higher than that of coaxial cable and twisted pair.

The first one must be wrong, the cost of optical fiber is very high, and ordinary people are not blessed to enjoy it.

Optical fibers are a subtle and flexible medium that transmits light beams. Optical fiber cable consists of a bundle of fibers, referred to as fiber optic cable. Fiber optic cable is one of the most effective transmission mediums for data transmission, and it has the following advantages:

1) The frequency band is wider.

2) Good electromagnetic insulation performance. Optical fiber cables transmit light beams, which are suitable for long-distance information transmission and high security because they are not affected by external electromagnetic interference and do not radiate signals to the outside world. Of course, the difficulty of tapping is an inherent problem, as the cut cable needs to be regenerated and re-signaled.

3) The attenuation is small. It can be said that at longer distances and ranges the signal is a constant.

4) The interval between repeaters is large, so the number of repeaters in the whole channel can be reduced, which can reduce costs. According to the test of Bell Labs, when the data transmission rate is 420Mbps and the distance is 119 kilometers without repeaters, the bit error rate is 10-8, which shows that the transmission quality is very good. Coaxial cables and twisted pairs, on the other hand, require a repeater every few kilometres.

In applications where multiple minicomputers are connected using fiber optic cables, the unidirectional nature of the fiber must be considered, and if bidirectional communication is to be performed, then a double-strand fiber should be used. Due to the need for multiplexing and multiplexing of light at different frequencies, optical multiplexers have emerged in the communication device market.

Fiber optic cables can only transmit in one direction. In order to achieve two-way communication, fiber optic cables must appear in pairs, one for input and one for output. Optical interfaces are connected to both ends of the cable.

Fiber optic cables need to be installed with extreme care. Each cable is connected with a polished end and connected to the optical interface via an electric grill or chemical cyclochlorine process to ensure that the optical path is not blocked. The fiber must not be pulled too tightly and cannot form a right angle.

The benefits of using fiber optic cables in a network are as follows:

It's fast. **The highest line is a few megabytes, and the optical fiber can reach hundreds of megabytes.

Safe. Optical fiber uses optical signals, which are less likely to be eavesdropped on than ** wires. In addition, the value of optical fiber is relatively low, so it is not easy to risk theft.

The transmission distance is long and the coverage is large. Optical fiber transmission is not affected by the line, and the distance that can be transmitted is very long, and there is no problem for tens of kilometers. Compared to the ** line of a few hundred meters and a few kilometers, it is much stronger.

Less disturbance. **Wires are susceptible to lightning and may burn out equipment, while fiber optics are not affected by this.

National defense optical cable is a military optical cable for information transmission. It is a fiber-optic cable line used for communication, information transmission and reception required for military needs such as troop command and communication and coordination of various departments.

National defense fiber optic cables are different from civilian fiber optic cables and are absolutely protected. If it is prompted that there is the laying of national defense optical cables, then the nearby construction must be absolutely approved, and in most cases it is prohibited. Once sabotage, theft, or even theft of information from it, it is one more degree than the crime of sabotage of civilian facilities.

The importance of defense fiber optic cables

After laying the national defense optical cable, the state will erect a sign to remind the people that there is a national defense cable nearby, and they must not destroy it at will. And the masses also know that sabotage of national defense fiber optic cables will be severely punished, so the masses will never go close to national defense fiber optic cables.

In order to guard against spies, China also assumes a large number of surveillance cameras at the location of the national defense fiber optic cable, these cameras will work 24 hours a day, once someone destroys the cable, the relevant server will immediately mark the location of the abnormal signal, so as to facilitate the military and lock the location of the spy.

Hello, I am glad to answer for you: the main function of optical cable is optical signal transmission, which can meet the specifications of optical, mechanical and environmental performance, and is usually placed in one or more optical fibers wrapped in a sheath, and can be made into communication cable assemblies alone or in groups.

Fiber optic cables transmit communication information, for example, the network wifi signals you use at home are transmitted through fiber optic cables.

Optical fiber cables are used to transmit communication information, and optical cables have brought people to the Internet era.

Optical signal transmission. Fiber optic cables are manufactured to meet optical, mechanical, or environmental performance specifications and utilize one or more optical fibers placed in a jacket as the transmission medium and can be used individually or in groups. Optical cable is mainly composed of optical fibers (glass filaments as thin as hair) and plastic protective sleeves and plastic sheaths to realize a kind of communication line for optical signal transmission.

The optical cable is mainly composed of optical fibers (glass filaments as thin as hair) and plastic protective sleeves and plastic sheaths, and there are no metals such as gold, silver, copper and aluminum in the optical cable, and generally have no value. Optical cable is a communication line in which a certain number of optical fibers are composed of a cable core in a certain way, covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission.

Cables formed by optical fibers (optical transmission carriers) through a certain process. The basic structure of the optical cable is generally composed of several parts such as the cable core, reinforcing wire, filler and sheath, and there are also waterproof layers, buffer layers, insulated metal wires and other components as needed.

The benefit of fiber optic communication is that it provides a reliable, high-speed, high-bandwidth, and long-distance communication method. By taking advantage of the physical properties of optical fibers, data can be transmitted in optical starvation signals, enabling long-distance communication. The benefits of fiber optic communication are introduced and explained below.

First of all, fiber optic communication has the advantages of high speed and high bandwidth. Since the transmission rate of optical signals is very fast, fiber optic communication can achieve extremely high transmission rates and bandwidths. Compared with traditional copper cables, fiber optic communication has a higher data transmission rate and greater bandwidth.

This makes fiber optic communication very important when dealing with large amounts of data and multiple people accessing the internet at the same time.

Second, another great thing about fiber optic communications is its reliability. Since optical fibers are made of materials such as glass and plastic, fiber optic cables have very high durability and robustness. In contrast, copper cables are fragile and breakable, making them vulnerable to damage during long-distance communications and harsh environments.

In addition, optical fiber communication is more reliable than wireless communication because the light transmission is not subject to electromagnetic interference and radio wave interference.

Finally, another important benefit of fiber optic communication is its ability to span long distances. Due to the low energy loss of optical signals, fiber optic communication can communicate over long distances without the need for amplification by devices such as signal amplifiers. This makes fiber optic communication a very important role in international and global communications.

In conclusion, fiber optic communication has the benefits of high speed, high bandwidth, reliability, and long distance. Not only does this method of communication provide faster communication speeds and greater bandwidth, but it also allows for more reliable data transmission and communication across the globe. As a result, fiber optic communication is one of the most popular communication methods in the internet and communications industry today.
