LAN Cable – Understanding, Type, Function, Select CAT 5

LAN cableUnderstanding LAN cables

Lan cable(Local Area Network)is a type of network cable commonly used on cable networks used to connect devices such as PCs, routers, and switches on local area networks.

Various types of LAN cables are adjusted based on length & durability, if the LAN network cable is too long or of poor quality, it will make the network signal as less good.

From here comes various types of LAN cables along with abbreviated categories (CAT) with the aim that data delivery can be optimized to perform exclusive tasks in exclusive situations.

Most of us think we certainly have understood the generic disparity between ADSL, COAX and Fiber Internet, but the disparity of installation of cable types on the back of this network may still be many who do not understand.

The most common types of communication cables consist of three types, namely Twisted Pair cables consisting of UTP cables & STP cables, Coaxial Cables (Coaxial,) and Fiber Optic cables.

Understanding the differences between the three will explain how transmission data dabbles through each cable, as a result you will be able to determine exactly what type of cable you need.

Here is a general description based on the three types on the cable system of their respective functions:

1. Twisted Pair Cable (UTP/STP)

Twisted pair cables are a pair of insulated cables that are twisted together to help reduce noise according to outside sources, although it is said to reduce outside noise but these cables are still very vulnerable to outside noise.

Twisted pair cables are the type of cable using the most economical option according to all three but also the transmission bandwidth is lower and has a high attenuation. There are 2 types of twisted pair cables:

UTP Cable(Unshielded Twisted Pair)”Unshielded” is non-relies on physical shields to block interference.Generally, the type of UTP cable is used for housing and business purposes.There are several categories of UTP cables based on their ability to transmit speeds that are useful in increasing bandwidth, for example: CAT three, CAT five, CAT5e, CAT6.

STP Cable(Shielded Twisted Pair)”Shielded” uses foil jackets to block/cancel external interferenceCommonly used for large-scale companies for high-end applications where cable installation is generally in an open environment.

two. Coaxial/Coaxial Cable

A coaxial cable is a type of high-frequency transmission cable consisting of a single solid copper core, where data is electrically transferred through an internal conductor and has a transmission capacity of 80X greater according to twisted pair cables.

This type of coaxial cable is commonly used to transmit TV frequencies (higher bandwidth makes it more suitable for video applications) and to connect personal computers in the network.

Along with the development of data transmission stability, the ability of coaxial cables also develops where coaxial cables can effectively protect frequency from interference. Although the cost of creating a coaxial cable network is more expensive than twisted pair cables but more economical when compared to optical cables.

There are also 2 types of coaxial cables:

Coaxial Cable 75 OhmGenerally often used for video signal transmissionIt is often used to connect video frequencies between different components such as VCRs, DVDs, or better known receivers using the cable name A/V.

Coaxial Cable 50 OhmThis type of cable is especially used to transmit data frequencies on 2-way communication systems.Most commonly used for computer backbone networks, AM/FM radio receivers, GPS antennas, police scanners, and mobile phone systems

three. Fiber Optic Cable

Fiber optic cables are the latest technology on transmission cables, rather than transferring data through copper cables, fiber optic cables containing fiber optics even transmit data through light (not electrical pulses).

Each optical fiber is coated with a layer of plastic that resides in a protective tube, making it highly resistant to external interference.

The result is a very powerful and super fast connection that has a data transmission capacity of 26,000X more poly than twisted-pair cables, it can be said for this time fiber optic cable is the best type of LAN cable and of course the construction of fiber optic cable network is very expensive.

Fiber optic cable consists of 2 types of fiber cables, namely:

SinglemodeIt has a mini core where the amount of light reflection will decrease when it passes through the core so that it is only possible to propagate in one light mode at a time.It means low attenuation so that data transmission can be done at long breaks very quicklyCommonly used in telecommunications, CATV networks, and universities.

MultimodeHaving a larger core diameter as a result allows multiple modes of light dispersalThe amount of light reflection increases as it travels through the core, allowing more poly data to be traversed.Due to its high dispersion, multimode fiber optic cables have lower bandwidth, higher attenuation and reduced frequency when traveling.Most generics are used for short-distance communications such as LANs, for security systems, and for public networks.

How to Choose a LAN Cable

All types of LAN cables have the same basic purpose or function of connecting devices to a network, such as the internet. However, the entire LAN cable is exactly the same.

If you’ve ever needed a LAN cord without knowing which cable you’re obligated to choose, you’re not alone. Currently LAN cable has become the default internet network cable, but of course you will have difficulty choosing the type of LAN cable that is suitable for you if you do not read the stroke of the pen below. 1. Adjust Your Needs

The easiest way to choose a cable is to choose a cable from the range &performance you need. But what do you need?

For example, such as the speed of your home internet connection, if you are still using the old network cable then your internet connection will certainly be slower, say 10 or 20 megabits per etc., then you should choose a cat cable five or later. 2. Pay Attention to the Router

Next is consider the router you have, this is because some cheap routers only support data transmission up to 100 megabits per amp, as a result even if you buy Cat 5e cable or even higher, it will only be a waste of your money.

Even the most beautiful types of residential routers sporadically support more according to gigabits, as a result using Cat 6 or Cat 7 cables is tantamount to using waste.

From the conclusion, then Cat 6 cable can be a beautiful choice for you &y for the use of the maximum home network Cat 5e.What is “Cat”?

If you often browse using the keyword “network cable” of course the cable you see must have a classification such as Cat five or Cat 6e, then what does it mean by “Cat”?

“Cat” stands for Category, and the number behind it is the specification of the cable produced. A rule is usually a higher number representing a faster speed and higher frequency, measured at Mhz.

Like other types of technology equipment, newer types of cables tend to support higher bandwidth, so newer cables will speed up faster downloads and network connections.

Be sure to keep this in mind that a longer type of network cable will form a slower transmission speed, even if the cable has a high specification label.

From this, most types of cables for exclusive use sold in sporadic market exceed 100 meters as a result of which it is unlikely to decrease in speed.

Below, you can see the specifications or capabilities of each type of cable.

Types of Paint Cables

For cat three and cat 5 cable types, including old /obsolete category cable types. Even so, it is not strange if you still find Cat 5 cables used but for the type of Cat three has almost rarely been used.

However, it is best not to buy a Cat five cable even though it is cheap because the transmission speed is slow and has also not been produced in some countries. Cat 5e
