Why can t optical fiber replace copper cables?

Because the development of optical fiber is not perfect enough, it cannot be replaced.

Because the production cost and life of copper wire are far better than that of optical fiber.

This is mainly a matter of cost, and the cost of copper wire is more than one or two times cheaper than that of optical fiber.

The main reason is that the cost of optical fiber is too high and not cost-effective.

Because the ** of copper network cable is still very cost-effective, and the speed is acceptable.

Because copper cables and network cables are relatively cheap, they can be made more.

Because fiber optics are still in the process now, the speed is not very fast, and it is relatively expensive.

Because the ** of copper cable is still very attractive, it will not be too expensive.

The main problem is the cost, and most people are still reluctant to change the price.

This is because there is a big difference in cost between the two.

Because the ** of copper cable is still very cost-effective, and the speed is also acceptable,And the development may not be perfect, so it is irreplaceable.

Although driven by the increasing bandwidth requirements of data centers, optical fiber occupies a larger share in data centers, especially backbone application networks, with its advantages of higher transmission rate and wider bandwidth, in fact, copper cables are still an indispensable part of data centers, and they are also indispensable in applications In special environments such as voice transmission and power supply, copper cables are a kind of cable that cannot be replaced by optical fiber.

In the comprehensive horizontal wiring within the range of 100m, the optical fiber is inferior to the copper cable in terms of maintenance, cost, wiring, etc. The fiber core in the optical fiber is a special type of glass optical fiber, which is more vulnerable than the copper core in the copper core cable In the wiring and later maintenance, if you do not pay attention to the optical fiber, it is easy to be damaged and increase the cost From the current market situation, although the optical fiber has declined, it is still higher than the general copper cable. As a result, copper cables are easier to route and maintain and less expensive than fiber.

In applications such as voice signal transmission and wireless access, PoE power supply systems, optical fibers cannot replace copper cables. First of all, because copper cables are different from optical fibers, copper cables can support voice signals when transmitting data through electrical impulses, so copper cables can be applied to voice transmission, while fiber optics cannot. Secondly, because the glass fiber used in optical fiber cannot conduct electricity, while the copper in copper cable can conduct electricity, so copper wire can supply power while connecting data, so it is widely used in wireless access, POE power supply system, LED power supply system, etc.

At this stage, copper technology is still in the development trend of continuous scientific researchIt is easy to consider the connection requirements of a large number of machinery and equipment in the future, so you don't have to worry about it being defeated in time.

As a transmission medium, leather fiber optic cable is lower cost, easy to maintain and easy to install than old twisted pair cables. It can be equipped with a larger bandwidth. For home networking, twisted pair cables are sufficient. However, for the network service provider to the user side, optical fiber is definitely better than network cable.

The difference between optical fiber and broadband actually refers to the access mode of broadband, which ultimately directly affects the network speed. We know that the initial use of ordinary broadband is generally made of copper wire, but the use of wire to transmit network signals, its speed is very slow. In contrast, fiber optics transmit signals much faster.

Handling 5G is one step faster, the traffic is half cheaper than 4G, the broadband speed is 500M, and it is convenient and fast to log in to the online business hall of Guangxi Telecom to handle broadband, number card, traffic package, etc. with one click. Customer service No. 2 will answer for you.

The big difference is that optical fiber broadband is transmitted with optical cables, that is, optical transmission must be fast and copper is much slower, otherwise optical fiber will not be so expensive, especially professional optical fiber 10m 3,000 yuan a month Hehe.

In the cabling industry, the battle between fiber and copper has been going on for more than a decade. Nowadays, with the continuous emergence of new services such as cloud computing and 5GThe scale of data centers continues to expand, its architecture and cabling are becoming more and more complex, and the lightweight and gradually reducing costs of optical fibers make the demand for optical fibers for backbone network equipment more and more vigorous, and the proportion of optical fiber in large data centers is as high as more than 70%, far higher than copper cables, so does this mean that copper cables will be completely replaced by optical fibers? Not really.

Why will copper remain an integral part of the data center?

Although, driven by the demand for higher bandwidth in data centers, optical fiber occupies a large share of data center deployment due to its higher transmission rate and larger bandwidth, especially the backbone application network; But in fact, copper cables will still be an indispensable part of the data center, and in special environment applications such as voice transmission and power**, copper cables are cables that cannot be replaced by optical fibers.

In the integrated horizontal cabling within 100 meters, optical fiber is inferior to copper cable in terms of maintenance, cost, wiring, etc. The core of the fiber is a special type of glass fiber, which is more fragile than the copper in the copper cable, and if the fiber is not paid attention to in the wiring and later maintenance, it will be easily damaged, which will increase its cost; As far as the current market situation is concerned, although the ** of optical fiber has decreased, it is still higher than that of copper cable in general; As a result, copper cabling and maintenance are easier and less costly than fiber optics. 

In the transmission of voice signals and wireless access, POE power supply system and other power applications, optical fiber cannot replace copper cables. First, because copper cables are different from optical fibers, data is transmitted through electrical pulsesVoice signals can be supported, so copper cables can be used for voice transmission, but fiber optics cannot. Second, because the glass fiber used in optical fiber cannot conduct electricity, and the copper in the copper cable can conduct conduction, therefore, the copper cable can be used for data connection at the same time, so it is widely used in wireless access, POE power supply system, LED-based power system, etc.

Because the cost of fiber is too high, and the cost is not generally high. There is no substitute yet.

This is because the most essential way of network communication now still relies on network cables.

Because of the role of copper network cables in various fields, there is no way to replace optical fibers.

Although, driven by the demand for higher bandwidth in data centers, optical fiber occupies a large share of data center deployment due to its higher transmission rate and larger bandwidth, especially the backbone application network; But in fact, copper cables will still be an indispensable part of the data center, and in special environment applications such as voice transmission and power**, copper cables are cables that cannot be replaced by optical fibers.

Because copper cables are still an indispensable part. There are places where this is necessary.

Because optical fiber has the advantages of higher transmission rate and larger bandwidth, it occupies a large share of data center deployment.

This is because there are a lot of things that don't apply very much.

This also depends on the specific distribution of communication companies, such as ours, which is almost all optical fiber.

Because the material is different, the quality of the production is also different.

In most data centers, fiber optics have dominated the market due to the high demand for bandwidth. In addition, fiber optic cables are not subject to electromagnetic interference, and their installation environment requirements are not as complex as copper cables. As a result, fiber optics are easier to install.

However, it should be noted that although the gap between fiber and copper has narrowed, the overall fiber optic cable is higher than that of copper cable. As a result, fiber optics are widely used in environments that require higher bandwidth, such as data centers.

On the other hand, copper cables are less expensive. Fiber optics are a special type of glass fiber that is more fragile than copper cables. As a result, the cost of routine maintenance for copper cables is much lower than for fiber optics.

It also provides backward compatibility to older 10 100Mbps legacy Ethernet devices. As a result, copper cables are still used in voice transmission and indoor network applications. In addition, applications of horizontal cabling, Power over Ethernet (PoE), or the Internet of Things are driving the use of copper cables.

As a result, fiber optics will not completely replace copper cables. In fact, fiber and copper solutions will coexist for the foreseeable future, and each will be used where it makes the most sense.

1. Maximum speed: optical fiber broadband can reach more than 1000m; The maximum bandwidth of copper cable can only reach 10m;

2. Access line: optical fiber broadband is fiber to the home; Copper broadband is accessed through ordinary ** twisted pair cables;
