Why network cable can't be replaced by fiber optic cable?

With the development of Internet technology, we have an inseparable relationship with the Internet. Generally speaking, fiber optic cable and Network Cable are the two well-known network transmission options, but some people will ask why fiber optic network speed is so fast, people still choose network cable over optical fiber, why optical fiber does not replace the network cable in thousands of homes. Let's explore the pros and cons of optical fiber and network cables.

Fiber Optic Cable
Advantages:
1, optical fiber is the fastest transmission medium, can easily reach 100, gigabit or even 10 gigabit transmission requirements. The transmission of optical fibers is much higher than that of network cables.
2, the network is stable and the attenuation is small, the anti-interference ability is strong.
3. The transmission distance is much higher than that of the network cable. Generally, optical fibers are used for interactive multimedia information, such as work conference video, network interactive games, and remote video surveillance.
disadvantages:
1. The maintenance cost of optical fiber is high, because the material of optical fiber is mostly glass fiber. If it is broken, it needs special personnel with special equipment to weld, and ordinary people cannot complete it.
2. Optical fiber supported network cards and routers are not popular, so the cost of purchasing their accessories is very high.

Network cable :(CAT5E/CAT6/CAT7/CAT8)
Advantages:
1. The network cable is transmitted by electric pulse, which is very suitable for voice transmission, while the optical fiber is not. The application scenarios of network cables are mainly for engineering cabling, network connection, and connection of device port systems, such as switches, hubs, and firewalls.
2. The cost of the network cable is very low, and the technical threshold is low. Ordinary people can independently complete the connection of the network cable and the production of the crystal head with a little learning.
disadvantages
1, the transmission distance is far less than optical fiber, network cable transmission distance theoretically is less than 100 meters.
2. If the transmission distance exceeds the distance it can withstand, the signal will decay, and the network signal will be interrupted in serious cases.

Therefore, network cables still play an important role in voice transmission, indoor network, integrated cabling, and POE system applications. They will not be completely replaced by optical fibers. The technology of network cables is still being updated to meet the requirements of more devices in the future. Therefore, there is no need to worry that it will be obsolete.
