A Network Cable is a type of cable wiring used in telecommunications that relay data from individual computers to a larger network mainframe. Sometimes these cables are external and can be used to do things like plug computers into Internet modems or grounded ports. They can also be part of a larger infrastructure, and in these cases are often built into walls along with things like electrical working in order to provide ready access to Internet and cable television services. Several standard types of network cables exist, each designed for specific purposes.
1.Coaxial Cables
Coaxial cable, or “coax” as it is sometimes known, is another common type of network cable. It has a copper conductor in its center and a plastic coating serves as an insulator between the center conductor and a metal shield. The coating may be thin or thick; the thicker coating is less pliable but may provide extra protection.
2.Fiber Optics
Fiber Optic cables are used for networks that span large distances. As a result, this type of cabling has several layers of protective coating. It also transmits light as opposed to electrical signals like other cables. This makes it an ideal cable for network environments that are exposed to large amounts of electrical interference. It also transmits information at high speeds and is therefore used in large network environments like those used by big businesses.
3.Twisted Pair Cable
A twisted pair cable is a type of cable made by putting two separate insulated wires together in a twisted pattern and running them parallel to each other. This type of cable is widely used in different kinds of data and voice infrastructures There are 2 types of Twisted-Pair Cable the unshielded Twisted Pair Cable and Shielded Twisted Pair Cable
a. Unshielded Twisted Pair Cables
The unshielded twisted pair (UTP) cable is used in many homes and business-based Ethernet networks. It has four pairs of wires that are housed inside of the lining of the cable. Each pair is twisted into several additional twists to prevent interference from other devices on the network. The structure of this type of cable increases its reliability and helps minimize network failures, and as such is common over networks where there are a lot of users or, alternatively, a lot of connected computers.
b.Shielded Twisted Pair Cables
Shielded twisted pair is a special kind of copper telephone wiring used in some business installations. An outer covering or shield is added to the ordinary twisted-pair telephone wires; the shield functions as a ground
MEASURE TO BE TAKEN WHILE INSTALLING NETWORK CABLING DUBAI
It’s vitally important to take safety precautions when installing network cabling. Safety must not be compromised and some ground rules need to be followed first. Much of what you need to know for installing network cabling – How to identify it? How to buy it? And How to install proper connections. If you’re planning for Installing Network Cabling in Dubai, learning the basics of wiring and cable materials and installation is the best place to start. Understanding the basic wiring and cable terminology and identifying the most common types of wire and cables will help when investigating the wiring problems and when choosing the wiring or cable for new installation and remodeling projects.
1 Knowing Wire Sizing – The correct size wire is critical to any electrical wire installation. It indicates the diameter of the metal conductor of the wire. When choosing the right side of the wire, you must consider the gauge of the wire, the capacity and what the wire will be used for.
2 Understanding of Electrical Wiring Labeling – Electrical wires and cable have markings stamped or printed on their insulation or outer sheathing. These markings provide important information about the wiring and insulation, including the wire size and material, the type of insulation, the number of wires contained (inside a cable), and any special ratings or characteristics of the wire.
While looking at the color of wire or cable will help you narrow down the options at the store, reading and understanding the labels on wiring is the best way to ensure you get the properly rated material for your project.
3 Electrical Wire Color Coding -Color coding is the identification of individual wires. Knowing the uses of each color can help you identify what the wiring is used for and helps maintain consistency within an electrical system. The coloring on individual conducting wires usually does not indicate a size or rating but rather the standard or preferred use of the wire. For example, black and red wires typically are used for current-carrying or “hot” connections, and white wires usually are grounded “neutral” conductors. Green-insulated wires and bare copper wires are used for grounding wires.
WHY IS IT IMPORTANT FOR BUSINESSES TO HAVE STRUCTURED CABLING IN DUBAI?
You may have heard of structured cabling, and perhaps you’ve even considered it for your office or facility. With structured cabling, multiple electronic devices, such as computers and telephones, are connected by the technological infrastructure of the cabling system. There are many reasons why so many business owners choose this type of cabling system. Mastertech offers Etisalat/Du approved Network Cabling Dubai.
- SIMPLICITY One of the biggest benefits of structured cables is that they clean up messy wires. Replacing a multiple wire system with a structured cabling system makes the infrastructure much easier to manage. Any device simply needs to be plugged into the structured cable outlet, rather than connected manually to a specific wire. This makes a structured cabling system painless for employees to adapt to. New devices can be swapped in with no hassle or frustration. A structured cable system can carry data in all formats, including video and voice, so you can connect computers, printers, telephones, and fax machines easily. This stark simplicity is one of the biggest factors in many a business owner’s choices to switch to a structured cable system.
- FLEXIBILITY A structured cabling system provides an enhanced level of flexibility – helping to improve performance and drive business growth. This is because it can quickly and easily accommodate moves, adds and changes, which dramatically reduces installation time and ensures optimum adaptability to any network infrastructure changes. The flexibility also makes the system easy to take apart and move to a new office location.
- ADAPTABILITY A Structured cabling is a forward-thinking technology. If your business is planning to stay around, then structured cabling is a great investment for the future. Structured cabling can carry a very high bandwidth, which means it won’t become outdated in only a few short years. With high bandwidth, a structured cabling system can work well with emerging technologies and applications. No need to worry about how your cabling system will facilitate new equipment or your expanding business; structured cabling has got you covered.
HOW TO PRIORITIZE THE RIGHT FIBER OPTIC CABLE DUBAI?
Fiber Optic Cable is a very thin strand through which the pulse of light is transmitted. From data and voice to security and videoconferencing, many of Today’s IT infrastructure services rely on fabric optics to transmit information faster, farther and in a greater amount of data than ever before. Fabric optics are clear, and its bandwidth helps future proof networks for increased capacity needs and its reputation for reliability means worry-free maintenance. As with new any technology selecting the right products and determining the cost will be essential.
Here are some guidelines on choosing the right fiber optic cable.
Single Mode or Multi-Mode
Fibre Optic can be divided into Single-Mode Fibre Cable and Multi-Mode Fibre Cable.
Single Mode Fibre Generally as a core diameter 9um and requires laser technology for sending and receiving the data. It can carry a signal for miles its good for telephone and cable television providers while multi Mode Fabric permits the signal to travel in multiple modes, along the inside of the glass strand. It is available with fiber core diameters of 62.5 um or 50um.
INDOOR AND OUTDOOR FABRIC OPTIC
The difference between indoor and outdoor fiber optic cable is water blocking. Any conduit is someday likely to get moisture in it. Outdoor cables are used to protect the fibers from years of exposure to moisture. Indoor cables are what we call “tight-buffered” cables, where the glass fiber has a primary coating and secondary buffer coatings that enlarge each fiber to 900 microns—about 1mm or 1/25-inch, to make fiber easier to work with.
WHY BUSINESSES PREFER STRUCTURED CABLING IN DUBAI THAN CONVENTIONAL CABLING SYSTEM?
One of the useful updates you can make to your network is a switch from Conventional Cabling which may also call point to point cabling system to a highly functioning Structured Cabling System.
CONVENTIONAL CABLING VS. STRUCTURAL CABLING. These are the two methods for transporting data through network cables. Some continue to use conventional cabling for their data infrastructure.
Conventional Cabling or Point to Point Cabling System– is set up by connecting one component of a network, a server, switch or a device directly to another component of the network using fabric optic cable. This requires long cords that can get tangled up and may confuse technicians who are trying to make changes.
Twenty Years ago this system was a popular solution for quickly and easily stringing together a network but at that time the network was small and the IT department was smaller.
There are many reasons why a structured cabling system is better than conventional cabling
Today’s as the network grows and fast transfers of large amounts of data are more necessary to operate them, maintaining these older point systems, along with the thousand cords to operate them places in a big stain on a company’s IT resources.
A Structured data cabling approach takes a more logical and longer-term approach. It examines where the cabling is needed and organizes it cleanly and simply within a network of routers, switches, and hubs. This consistency in cabling means that it is far easier to install and troubleshoot everything on your network, from phones and fax machines to servers and desktop computers.
When you have structural cabling in your business, you can enjoy consistent, predictable performance, optimize system availability, streamline the use of your cabling, have backups in place if anything goes wrong, and enjoy a flexible system where it is easy to make changes without having to shut down your whole cabling array while the technician figures out how to adjust the setup without interfering with other company systems. Also, it can reduce human error and downtime. In a structured cabling system, if there is a disconnection or a wrong connection, it will affect the whole system and you will know immediately and be able to correct it right away.
