The Advantages and Disadvantages of Network Data Cabling

With more and more devices and electronics being designed to make use of wireless networks for network connectivity, it's necessary to evaluate network data cabling before setting up a new device or system in your home or office. In many cases, a network that makes of use physical cabling will be more robust and secure network than a one based upon wireless technology. Read on for a few of the advantages of network data cabling, as well as some of the disadvantages with respect to wireless networks.

Security

One of the primary advantages of network data cabling is that they provide a higher level security than wireless networks. Although measures of security including passwords and protected Wi-Fi networks help to improve the security for wireless networks, they are never as secure as network cabling systems.

Reduced Interference

Proper installation of network data cabling helps to dramatically reduce the interference caused by electrical and radio frequency, known as electromechanical interference and radio frequency interference, respectively. Wireless networks are extremely susceptible to radio frequency interference problems. This is not the case with shielded network data cabling and fiber optic cable.

Consistent Connection

One of the biggest concerns that many wireless network users have is the inconsistency of the connection. As data transfer is performed, a lapse in the network connection caused by a momentary lapse in the wireless signal or electrical interference can effectively negate a great deal of work, slow down the transfer rate considerably, or introduce unacceptable levels of data corruption. Fortunately, network cabling provides a consistent connection that does not suffer from these momentary lapses.

Speed

Although not all network cabling will provide a speedy connection, the newer types of twisted pair data cabling can operate at data rates up to 10 gigabit. Fiber optic cabling transmits light rather than standard data information, making it optimal for high speed usage and extended ranges.

Mobility

One major disadvantage of a network data cabling setup is the mobility while connected to the network. Wireless networks provide excellent mobility for electronic devices because there are no wires to hinder movement, within the range of the transceiver. Unfortunately, users must be directly connected to a network cabling system in order to take advantage of the data transfer possibilities.

Expandability
If more than one physical computer connection is required when physical network data cabling is used, it's normally a simple matter of connecting a router or hub to the network cabling already installed and connecting network devices to the hub or router. Each hub or router can support up to 255 devices.

Wiring Setup

Whereas wireless networks are relatively easy to set up, a physical network data cabling system must be installed prior to use. This means that the cable must be routed and terminated properly at both ends. This normally means obtaining access to crawl spaces and the interiors of walls as well as cutting holes in walls.

Types of Voice Data Cabling

Cabling is the material and system through which data and information is transferred from one device to another. There are many different applications for cable materials, including transmitting telephone data, computer network data and much more. Voice data is one of many types of information to be transmitted in this way. When installing a system to transfer data of this type, you have a number of different options from which to choose.

Unshielded Twisted Pair

Unshielded twisted pair cable is typically the least expensive type. Often known as UTP cable, this is made up of pairs of wires that are intertwined around one another inside of the larger cable framework. The reason for this twisting is to help the smaller wires avoid interference from both electrical and radio influences. UTP is susceptible to a moderate degree of interference, though this is often not a concern for voice data information transferring.

Shielded Twisted Pair

Slightly more expensive than UTP cable is shielded twisted pair cable, often referred to as STP. This cabling is similar to UTP in many ways, although the wires within the cable framework are shielded by a braided metal band. This helps to protect them from electrical frequency interference, making the connection more secure and reliable.

Coaxial

Coaxial cable is one of the most common types of material used for the purposes of transmitting voice data. This type of is constructed with a core of copper, which is an excellent material for transmitting information data. The copper core is surrounded by a thick plastic barrier and a metal shield, both of which help to provide coaxial cable with a better protection from interference due to electrical and radio sources than either UTP or STP. Coaxial cable can be somewhat more difficult to install than these other types, however.

Fiber Optic

Although it is oftentimes the most expensive type of cable to purchase for a project of this type, fiber optic is both the fastest and the most highly resistant to interference. Fiber optic materials make use of a flexible glass core. Rather than transmit standard data bits, these cables transfer light. This eliminates the risk of electrical interference and also allows the data to be transferred over much larger distances than for any of the other types listed above. Fiber optics are generally also much faster than these other types, too.

To find the best type of cable for your voice data cabling project, it's best to speak with a professional data cabling installation expert. They can help you to determine which material will be most conducive to a successful connection and a high speed transfer capability.

Types of Data Cabling for the Transfer of Digital Information

Although many people take it for granted, data cabling is one of the most important frameworks for Internet, television and phone usage around the world. Data cabling refers to the structure of cables and networks that is used to transmit digital information from one place to another. Because there are many types of information that are transmitted in this way, there are a variety of types of equipment and supplies.

Unshielded Twisted Pair

One of the most common data cabling devices found throughout the country is the unshielded twisted pair cable, commonly known as a UTP. This can come in many different grades to allow the transmission of all types of data and at different data rates; for example, UTP commonly ranges from telephone-grade up to very high-speed wire. The unique fixture of UTP is that the individual wires within the cable are paired off and twisted together. This helps to eliminate interference from wires within the same cable, thereby allowing for a greater density of wires per foot and, following from that, a heightened opportunity for the transmission of data.

Shielded Twisted Pair

Any data cabling overview would not be complete without a mention of the shielded twisted pair cable, also known as a STP. While more expensive than UTP, the shield mechanism on the wires within an STP cable help prevent the interference of radio and electrical frequencies outside the data transmission source. Therefore, the data cabling use for shielded twisted pair cable is open to many more locations and options than UTP, and it is more secure as well.

Coaxial

One of the most common types of data cabling material found throughout many homes around the world is coaxial. This cable makes use of one single copper conductor. The copper conductor is shielded by a thick plastic layer and a metal shield. As a result of this thick insulation layer and the metal shield, coaxial cables are highly resistant to any form of interference from electrical or radio sources, making them a very secure way of transmitting data.

Fiber Optic

Composed of a central core of glass surrounded by layers of protective shielding materials, fiber optic cable operates by transmitting light instead of electronic signals. This effectively not only limits the problem of electrical interference, but it also allows for rates of data cabling transfer that are much higher than many of the other types of cabling. The fact that this can transmit data much farther than the other types makes it a natural choice for many types of cabling needs at this point.

The individual type of cabling that you'll need for any project at home or at work will depend upon the benefits and disadvantages of the types you're interested in. Consult with a data cabling specialist for more information about how to select the right setup for you.
