You already know about network cables and fiber optic cables

Maybe you are the general manager of a large corporation in the world or simply a farmer in his twenties, but the simplest need you have is an Internet connection to surf the web watching movies for example. What are the following factors?

  • Connect quickly
  • Secure connection
  • Reliable connection

But if you are a regular Internet user, then you probably will not be able to fully understand the strengths and weaknesses of the two most common types of cabling today. and network cables. So to help you better understand these two issues in this article we will provide more information to help you make the most appropriate decision for your individual or collective needs.

  • A brief history of formation.

1. Network cable.
Discovered by the famous doctor Xerox in the early 70s of the twentieth century. But later in detail in 1980 was introduced and developed widely. Copper wiring is the most common method in LAN. Network cabling was previously slower than optical cabling, but that has now changed. Can clearly see the current tooisn multi-wire CAT 5E Cable Japan can reach up to 1Gbps / 1s. CAT 6E Golden Jpan cable with a speed of up to 10Gbps per 1s, but limited in this range is limited to 10m and is used most in Game bars.

Cat5e network cable is short for English: Ethernet Cable Catgory 5 Enhanced. To be able to reach the speed
Cat5e cable, Cat6 Golden Japan is composed of four pairs of twisted copper wires
together. Two of the four pairs carry the message and the other two hold the function
receive information.
2. Optical cable.
Optical cables were used by NASA and in the use of television cameras in 1969 during a lunar expedition. Today, fiber optic cable is used in the transmission of Internet signals thanks to the outstanding advantages of speed and distance further.
Fiber optic cable is formed from ultra-thin optical fiber glass that is extremely fragile carrying technical information
Numbers instead of electronic currents like regular network cables. Fiber is divided into two basic types: Single-Mode
and Multi-Mode. Single-Mode optical fiber cables use laser light to transmit and receive signals. SingleMode optical fiber
Thinner than Fiber Optic Multi-Mode. Light-emitting diodes (LEDs) are used to send signals in the cable
Optical Multi-Mode and Multi-Mode Optical Cable are used in short distances. In principle, speed
Optical fiber transmission is in the range of 10Mbps to 10Gbps.
II. Compare
1. Noise

UTP cable or network cable is usually non-interference, so it is very vulnerable to electromagnetic interference for anybody
We also work in an environment where there is an electrical signal. However, as mentioned above, Golden Link is currently
with Cat5e SFTP Interference Cables and Cat6 SFTP Interference Cables can solve most of the electromagnetic interference problems. But anti-interference cable will become useless when working near high voltage places such as generators or high voltage substations ... optical fiber will be a good choice now as fiber optic cables work well. Through the transmission of light, the impact of electromagnetic interference is not worth the attention.
2. Security
Network cable signals are easy to block and steal and only the new switch can improve security. Information sent via optical fiber is transmitted by light so it is difficult to block and steal.
3. Speed
To date, fiber is always considered to be able to "run" faster than the network cable. But that was it
gradually changed since the appearance of Cat6 and Cat6a network cables. As the information mentioned at the beginning of the article
Cat6 cable can reach 10Gbps and is limited to 10m. So now Cable
In terms of speed, it may be possible to catch up with fiber optic cable but considering the aspect
By the way, fiber optic cable is still showing its superiority when it can work hundreds of kilometers.
4. Fire and explosion safety
While fiber optic cables are relatively safe in fire and explosion because they do not use electricity to transmit information
Network cables are always at risk because they always carry enough electricity to cause a fire. Because the
Always carry the potential fire risk, so all Golden Link network cables are equipped with the shell
100% new PVC (Do not use recycled materials), durable, durable, environmentally friendly and solid.
Most notably, it is highly fire resistant.
5. Bandwidth
Network cables provide less bandwidth than optical cables. For example, Cat 6a can forward 600MHz over 100M, but Multi-Mode Optical Fiber can forward 1000MHz along the same distance.
6. Cost
For home use needs to surf the Facebook, see Youtue or office work in joint
Small business ... the network cable will be cheaper than the fiber optic cable. But recently the cost of cable
Optical components and its characteristic hardware have been gradually reduced. But overall cost to
Use of fiber optic cable is still more expensive than pure copper wiring or CCA cable, if ignoring the time factor,
weather, durability, speed, dead time, fire risk ...
