Cables and Connectors for Networking and Computer

Cables used for building the infrastructure of computer networks are available in a wide range of species. Among the most popular – coax, twisted pair and optical fiber. What are the specifics of each of them? What are the most common features of the installation – a twisted pair? Among the most historically earliest types of cables used in network connections is coaxial. According to the thickness of it roughly corresponds to the power cable supply for your computer, designed to work with the socket 220 V.

On top of it is a braid of copper or aluminum. The outer layer is the insulating sheath. The connection of this type of network cable can be accomplished by:

– BNC-connector;

– BNC-terminator;

– BNC-T-connector;

– BNC-connector Burrell.

Consider their specific details. The BNC-connector involves placing on the ends of the cable, used to connect to T- Burrell-connectors. BNC-terminator is used as an insulating barrier to the movement of the signal via cable. Correct operation of the network without this element, in some cases not feasible. Connecting via the network cable coaxial type involves the use of two terminators, one of which requires grounding. BNC to PL-259 adapter is engaged to connect the PC to the main highway. In its structure, there are three slots. The first terminal is connected to the network card of the computer from using the other two carried out the connection across the backbone. Another type of connector for coaxial cable is BNC-barrel. It is used to connect different pipe ends or to increase the radius of the computer network.

Today, most probably common for computer network cables are called “twisted pair”. Why this name? The fact is that the cable structure of this type presents the pairwise conductors. They are made of copper. Standard cable type under consideration include 8 cores (of, thus, 4 pairs), but there are samples with four conductors. The so-called network cable of this type (the correlation of each strand with a particular function) involves the use of a specific color of insulation on each conductor. External insulation twisted pair is made of PVC, which ensures sufficient shielding conductive elements from electromagnetic interference. There shielded cables of this type – FTP and STP. The first relevant responsibilities foil placed overall lived in the second – on each of the conductors. Any modification of the unshielded twisted pair is UTP, typically, more expensive cables with foil. But they should be applied only if there is a need for high-quality data transmission at a relatively large distance. For home, networks are well suited unshielded twisted pair. For testing the cable, you can use a wire toner tracer.

There are several classes of the appropriate type of structures, each of which is referred to as CAT with the number from 1 to 7. The higher the corresponding figure, the better materials ensure signal transmission. Modern network cables to your computer to exchange data over Ethernet home networks suggest matching items CAT5 class. You can get a CAT5 toolkit. In compounds where activated, twisted pair connectors are used, which will be properly classified as 8P8C, but there is also an informal name them- RJ-45. It may be noted that the cables corresponding to at least grade CAT5 and CAT6, can transmit data at speeds close to the maximum for this type of structures – up to 1 G / sec. BTW, you can get almost all kinds of networking and computer cables and connectors from for good price and high quality.
