modular cables in Dubai UAE

There are different types of high quality communication cables equipped with modular plugs. These cables are suitable for connecting the remote panel to the battery charger, inverter and data transmission, and they can also be used as parallel or 3-phase synchronization cables for different models.

Modular cables are available in different sizes in Dubai UAE. Available lengths include: 1, 3, 6, 10 or 15 meters (3, 9, 19, 33 or 49 feet). Visit Marineland in Dubai and Sharjah.

If you have paid attention to the wiring stage during the construction of a building, you have probably seen different types of cables. You may also be interested to know the reason for this amount of variation in a cable. In this article, we want to introduce the use of each of the different cables. Stay with us.

A cable transfers power between devices from one place to another. But the use of modular cables is very diverse. These cables are used to transfer data between two devices in two different parts of the world.

Cables are actually made up of one or more wires and usually have three parts, which are:

• Conductive

• Insulation

• Protecting the cables

Types of modular cables in Dubai

In mechanical applications, cables are used to carry objects and pull them up, this type of cable is also called mechanical cable or tow wire. For example, electrical cables are used for a wide variety of purposes. Each cable is designed for a specific purpose.

There are different types of cables, but some types of cables are used more than others, and in this section we briefly explain their uses.

1. Twisted pair cables

These cables actually consist of a pair of cables twisted together, this type of cable is used for long distances.

2. Multi-conductor cables

They consist of several conductor wires with an insulated sheath. These cables are used in remote control circuits.

3. Coaxial cables

It has a conductor surrounded by a foil conductor, which is insulated between the two. The most common use of this type of cable is in TV antennas.

4. Building power cable

All building electrical cables are made up of two parts: conductive wire and protective part.

5. Optical fiber cable

It consists of glass fiber bundles inside an insulating cover. Fiber optic cable has a higher bandwidth compared to wire cables. This cable is used in telecommunication applications.

6. Ribbon cable

It consists of several small cables parallel to each other. It is mostly used in electrical systems to connect peripherals such as disk drives in computer cases.

7. High voltage cable

There are other types of cables that are made with conductive metals such as copper or aluminum and can withstand very high voltage. These cables have a voltage tolerance of about 400,000 volts.

8. Poor pressure cable

Low voltage cables are made of copper and aluminum like high voltage cables, but they are insulated with different polymers. These cables have a voltage level of up to 1000 volts.

The difference between single-wire and multi-wire cables

Multi-strand or multi-wire cables have more flexibility. Also, these cables show more resistance to factors such as weather changes. Multi-wire or multi-strand cables are more expensive.

Single strand and wire ropes are usually used for transporting objects or towing.

The use of cables in computer systems

In terms of application, there are two types of computer cables:

• Data transmission cable

•        Power Cable

A data cable is a cable that provides a connection between your monitor and another device, such as HDMI, DVI, VGA cables. For example, a data cable transfers data to your computer and displays an image on your monitor. . The power cable provides the power your computer needs.

Below are the types of cables in terms of performance in the computer:

AT: Used for keyboard.

ATA: Used in hard disks and disk drives.

CAT5: Used for network card.

COAXIAL: Used for television or projector.

Composit: These cables are called composite and are used with consoles or projectors or televisions.

These cables are also known as RCA cables.

DIV: Used for projector screens and monitors.

ESATA: Used for external drive.

HDMI: used for monitors and projectors, DVP, blurayplse, etc.

Display Port: Used for displays or monitors.

Introduction of Rj45 modular cable

Typically, information is sent along cables. To access this information, you need a proper connection to the RJ45 connector. Your cable must end in a connector, which requires a jack for this connection (cable to connector). Now the question arises, what is RJ45? RJ45 is the standard physical connector in network cables, which is specifically used in Ethernet networks. And the number "45" is the number of interface standards. Recently, RJ45 connectors are seen with Ethernet and network cables. Ethernet cables with RJ45 connectors are called RJ45 cables. Newer Ethernet cables have small plastic plugs on both ends of the cable. The plug goes into the RJ45 jacks of Ethernet devices. In the following, we introduce this interface and its related details.

What is RJ45 connector?

The RJ45 connector is the most common twisted-pair connector in Ethernet cables and networks. "RJ", meaning "registered jack", is a standard telecommunications network interface. The physical connectors that registered jacks use are mostly modular connectors and 50-pin miniature ribbon connectors. The RJ45 connector is an 8-position, 8-contact (8P8C) modular plug and jack that connects most computers on Ethernet local area networks (LANs). RJ45 cable plug is made of plastic with 8 pins on its port. 4 pins for sending and receiving, and another 4 pins for technology Other or power network devices are used.

 Color code on RJ45 interface

As you know, there are two wiring designs: T568A and T568B, which are used to connect the twisted pair cable to the connector interface. When the RJ46 connector is attached to the cable, these two standards specify how the 8 wires are placed next to each other. These wiring arrangements each have their own color scheme and it is important to follow the color rules to ensure electrical compatibility.

 According to the two mentioned standards, there are two connection models. T-658B is the most common standard, so most devices support it. If both sides of the patch cords have the same standard, the connection is direct. Both standards (T568A and T568B) can be used for straight cable. If the connection is not direct, it is cross. Some network applications require cross-connecting, with a T-568A connector on one side and a T-568B connector on the other. When there is no router, hub or switch, this type of cable is usually used for direct computer-to-computer communication.

 Comparison of RJ45 and RJ11 connectors

What is the difference between RJ45 and RJ11? Other connectors mimic the RJ45 connector, and the RJ11 connector, used in telephone cables, is one such connector. The great similarity of these two connectors makes it difficult for ordinary people to distinguish them. RJ11 is a 6P 2C (6 position 2 contact) modular connector, which only uses 6 positions instead of 8 positions.

RJ45 and RJ11 are two common jacks, each with its own purpose. The biggest difference between the two is the difference in usage. RJ45 is used in networking, where you connect computers or other network components together. RJ11 is a cable connector used in telephone sets. In addition to usage, another difference between these two connectors is the number of wires in the connectors. If you look closely at both connectors, you will see that there are only four wires in RJ11 while there are 8 wires in RJ45. In general, the RJ45 connector is slightly larger than the RJ11. It can be concluded that you cannot put the RJ45 connector in the RJ11 slot, but the opposite is possible. Although the small size of the RJ11 makes it easier to fit it into an RJ45 slot, this is not recommended as it may damage the device that fits into the RJ45 slot. With proper knowledge and training, some people have been able to use RJ45s instead of RJ11s. At present, RJ45 jacks are usually placed in household outlets to reduce the number of wires.

Types of RJ45 Ethernet cables

Cables that have RJ45 connectors on both sides are called RJ45 Ethernet cables. Cat5, Cat6, and Cat7 are the most common RJ45 Ethernet cables used in today's networks.

Category 5 cable

Cat5 cable transmits at a frequency of 100 MHz and provides a line speed of 100 Mbit/s. Cat5 uses two twisted pairs (4 connections) up to a maximum distance of 100 meters. The Cate5e specification was introduced with more stringent features and standards. The new standard required new cables that include all 4 twisted pairs. Over short distances, under ideal signal conditions and assuming there are 4 pairs, Cat5 and Cat5e patch cables are capable of transmitting gigabit speeds. Gigabit Ethernet uses an optimized coding scheme, especially in terms of signal tolerances.

Category 6

Cat6 cable is compatible with Cat5e. This series of cables have strict standards and a better coating than their previous series. Cat6 cable was designed as a standard for Gigabit Ethernet and provides speeds of up to 1000 Mbps at 250 MHz. By reducing the maximum cable distance from 100 to 55 meters, these cables support 10 Gbps speed. Cat6a cables double the frequency to 500 MHz, while reducing noise interference with a grounded foil sheath.

Category 7

Cat7 cables are specifically designed to support 10 Gbps speeds and operate at frequencies up to 600 MHz. This cable has a separate sheath for each of the four pairs. Cat7 supports up to 100m distance, and is compatible with Cat5 and Cat6 cables. Cat7a increases the frequency to 1000 MHz, and supports future speeds of 40/10 Gbps.

RJ45 connectors are the main part of the Ethernet connection that transmits voice and data. These connectors are a smaller and cheaper alternative to the old methods. The simple plug-n-play method also reduces the difficulty of installation. Compared to RJ11, RJ45 has more applications. These applications include Ethernet network, telecommunications, factory automation and more. These connectors are often used in network devices including Ethernet cables, modems, computers, laptops, printers.

The quality of modular cables in the UAE

The thicker the cable, the faster the electrons pass through it. For the greater thickness of the cable, we will have more voltage and, as a result, a better quality cable. But the longer its length, the higher the resistance of the wire, the lower its quality. Thicker cables are more expensive and better quality.

Tips for choosing the right cable

• The permissible current of the cable must be more than the current we want.

• The cable cover should be chosen according to the environment and weather conditions and the cold air.

• Choose cables according to future developments and

• If we intend to develop, we must apply them in cable selection.

• The desired voltage should not be much lower than the cable voltage.

• To single phase or three phase Pay attention to the voltage consumption and the cable.

• The diameter and cross-sectional area of the cable should be affordable and it is not necessary to buy wires with a large diameter and thick for better quality.
