Why do you choose to connect your router and computer with an ordinary network cable when the fiber

For the use of the network, for today's high-speed development of the information age, it is really the daily use, especially at home, the basic mountain has to use switches, computers, network cables, etc., and when it comes to the transmission medium, everyone will think of network cables, optical fibers, etc., at this time people will wonder why the fiber is so fast and choose to use ordinary network cables to connect routers and computers? The main thing is the protocol of the interface, as well as the cost, etc., after all, this is a civilian thing, and if you want to expand the use, you must consider the cost.

It's not that the better the effect is the best, but considering the cost performance, for example, the network that meets the general user is actually enough, and the network is open to 100m for an average person, but in fact he only needs 10m is enough, of which 90m is a wasteful behavior, whether it is for users or manufacturers, this is a big waste, so from this point of view, even if it is said that the fiber speed is so fast, But in fact, it is enough for everyone to use an ordinary network cable to connect the router and the computer, and the network speed is completely sufficient.

And although there are 8 lines in the network cable, but in fact, the average user only uses 4 of them, if it is beyond the gigabit network at this time will use the other four, so at this point, the so-called optical fiber is really not used as a medium, the network cable can fully meet the needs of many people, and the cost is cheap, you can have better benefits, ** business and the like must be more willing to use it this way.

And for switches, computer motherboards, and routers, etc., the interfaces provided are all network cable interfaces, so even if the interface of optical fiber is used, in fact, the effect of the protocol is not reached, and the effect of support is not good, so the effect of using network cable is the best in general, whether it is the value or the benefits obtained, and the use effect of ordinary people is completely sufficient, there is no need to introduce optical fiber.

Although the fiber speed is fast, it is not stable enough, and the ordinary network cable is relatively stable and will not make big mistakes, so I choose to use the ordinary network cable.

Because it is impossible to connect the router directly to the router, it is still necessary to use an ordinary network cable.

Although fiber is fast, it is only suitable for long-distance transmission, and its texture is brittle and fragile, which is not suitable for computers connected to routers in the home.

1. The material is different.

Network cable is an indispensable communication connection equipment in LAN connection, which can be divided into three types: twisted pair, coaxial cable, and optical cable. Among them, twisted pair is a data transmission line composed of many insulated crossed wires. For example:

The common ** wire in our life is the twisted pair, which needs a crystal joint to connect with it.

Optical fiber, in fact, is what we often call optical fiber, which is a fiber synthesized by light on glass or plastic, which uses the radiation function of plastic to achieve the purpose of light energy conduction. In general, the fiber is encased in a plastic sheath so that it can bend and not break. After the pulse is detected through a light-emitting diode or a laser beam, the transmitter at one end of the fiber transmits it to the receiver at the other end.

2. The transmission speed is different.

The best Category 7 cable, its transmission frequency can reach at least 500 MHz, which is more than 2 times that of Category 6 and Category 6 cables, and the transmission rate can reach 10 Gbps.

Optical fiber is currently the fastest transmission medium, which can reach 40Gbps-100Gbps. In other words, it is at least 4 times faster than the network cable transmission.

3. The transmission distance is different.

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 you can't connect to the server; There is no signal.

Optical fiber can be divided into multimode fiber optic transceiver and single-mode fiber optic transceiver. Single-mode fiber optic transceivers: transmission distance from 20 km to 120 km; Multimode fiber optic transceivers: transmission distance from 2 km to 5 km.

4. The cost is different.

Take the same transmission distance of 100 meters as an example for comparison.

A secondary router can help improve network speeds, but there are a few reasons why it's faster than connecting directly to the primary route:

Secondary routers support wireless networks: With secondary routers, wireless networks can be used without using wired networks, making it easier to access the network.

Secondary routers support signal conversion: Secondary routers can convert the signal received from the main router into a signal suitable for computer use.

Secondary routers support data distribution: Secondary routers can distribute data to multiple computers to improve network efficiency.

Overall, secondary routers improve the stability and efficiency of the network, which makes the network faster. However, network speed is not only related to network hardware, but also related to factors such as network environment and network congestion. As a result, the impact of the L2 router on the speed of the network varies from case to case.

It must be that the network cable is faster because the signal is transmitted directly, there is no obstruction, and the wireless signal should consider environmental factors.

The network cable connected between the optical modem, the router and the computer is generally an Ethernet network cable, which can be used to transmit data and network signals. Connecting with different types of cables will have an impact on your speed, but not absolutely.

Ethernet cables are divided into multiple categories according to specifications, such as cat5, cat5e, cat6, cat7, etc., among which cat7 has the highest specification and the fastest transmission rate, while cat5 has the lowest specification and relatively slow transmission rate. Therefore, if the specifications of the network cable are lower than the requirements of the network equipment, the transmission rate and performance between them may be affected.

In addition, some poor quality or bad network cables can also cause network connections to slow down, disconnect, or other network issues.

As mentioned above, if you want to get faster network transmission rates and better network performance, it is recommended to use a higher specification network cable, and ensure that the network cable is of good quality. However, using lower spec cables doesn't necessarily affect the network speed, as they can still meet the needs of most network applications. Therefore, before selecting network equipment, you should choose the appropriate combination solution according to your own needs and actual situation.

Wired ones are faster and more stable, especially if multiple people use routing.

Difference Between Wired and Wireless:

1. The stability of the two is different. Wired is less affected by the external environment, data transmission is more stable, wireless is easy to be interfered by the surrounding environment, and wireless signal coverage is limited.

2. For the demand for Internet access, you can't measure wired and wireless with fast or slow, if the signal interference between the device and the wireless router is small, and the wireless performance is very stable, there is no difference between the speed of wireless and wired Internet, but the difference may lie in the data transmission between the local area network, that is, the data transmission between the computer and the computer, it can also be said that the transmission of the internal network is wired faster, and the wireless is weaker, but for home users, more applications are on the external network (Internet), There is not much difference between the two.

3. In terms of convenience of use, wireless is more convenient, not affected by the line, and can realize mobile Internet access. As long as the wireless signal is stable, it can meet the needs of Internet access, but if users have high requirements for Internet data transmission, consider using wired, data transmission will be more stable.

Wireless is affected by other electromagnetic waves.

This is inevitable, and the medium of transmission is not the same.

The wireless medium is the transmission of electromagnetic waves through the air, and the rate of transmission itself varies greatly.

What you mean is to connect the two computers directly with a network cable and through the router with a network cable.

Which of the two computers has a faster transfer speed?

The general network card is a 100 Gigabit network card, the transmission speed is about 11mb s, if the router is stable, the speed through the router and the direct connection are the same, wireless is definitely not as fast as wired. I hope my answer is helpful to you, thank you.

Theoretically, wired is a little bit faster than wireless, maybe milliseconds, you can't feel it. As for what you said more than 1m is the upper limit speed, mobile phones generally only support it, and now routers are all there, which can reach a speed of 54m, and it is no problem to be compatible with mobile phones. Mobile phones are OK, and so are computers.

It is not necessary that the optical fiber is faster than the network cable, and this needs to be seen which part is faster.

Because, optical fiber and network cable, are data transmission, two inside, one is the optical signal, the other is the electrical signal, if the loss attenuation is not considered, the signal in the two is the speed of light, from the perspective of a single signal transmission, the speed is the same.

However, 1For large-capacity data transmission, you need to look at the supported bandwidth. Generally, the network cable supports a bandwidth of up to 1G (approximately 1000M), while the optical fiber itself supports a bandwidth of several Gigs or even tens or hundreds of G

Therefore, if the data to be transmitted is very large, the optical fiber has a great advantage in transmitting large data in a short time (in the case of data exceeding 1G).

2.Considering transmission and reception, because the current electronic system (such as a computer, such as a server), can only identify electrical signals, can not directly identify optical signals, therefore, the network cable can be directly connected to electronic equipment, while optical fiber, must be converted into electrical signals through a photoelectric converter and then recognized by electronic equipment. Therefore, if the amount of data transmitted is relatively small, although the speed of the two is the same (you can't see the difference of a few nanoseconds), the latency of the optical fiber will be higher than that of a simple network cable.

Therefore, in this case, theoretically speaking, the network cable is fast.

In addition, network cable transmission, affected by electrical loss, is generally short (generally the highest unit of 100 meters), and the optical fiber distance is at least 2km (multimode), or even tens or hundreds of kilometers.

Therefore, in most cases, optical fiber is used as the backbone communication cable, and the network cable is used as the communication cable connecting electronic equipment at the end.

Since fiber optics are so fast, why don't you use ordinary network cables instead of fiber optics between the router and the computer?

ADSL broadband is generally 128K uplink and 512K downlink, and now some areas are downlink 1M, and some areas in Beijing are even downlink 2M or 4M. The higher the bandwidth, the faster the speed. **Internet access is ADSL, fiber to the home is LAN + LAN.

The difference in use is that the Internet speed may be affected when there are many people, but the optical fiber will not, and the network speed is very stable. Even if you use a good network cable, the network speed will be faster, because the network speed and those data are limited, and you can't control it. If you use a good network cable, you can only say that it will not affect the normal network speed because the network cable is not good.
