Different categories of network cables are available today for computer networks but they come with different levels of effectiveness and what is more is the fact that a cable must have to be compatible with the various devices used in a computer network. This is why choosing the right network cable is a baffling task for a network owner. A wrong selection of cable can result in data transmission issues like slow speed, crosstalk, signal loss and signal alterations and many such things. In order to optimize the efficiency of a computer network, you will be required to install switches and hubs and the cable you use needs to be compliant with the standard of these devises. network cabling services
Here follows a brief discussion of the different categories of network cable and their supports.
Unshielded network cable: One of the mostly used categories of network cables is the Twisted Pair cable. These cables, unshielded in design, contain eight copper wires of 22 or 24 gauge and these cables are twisted to make four pairs. The motive behind making four different pairs is to reduce electromagnetic interference.This network cable is very cost effective and it offers support for data transmission at a speed of the 1000 mbps. Naturally, this unshielded twisted pair cable is one of the most regularly used wires for computer network.
Shielded network cable: This cable is an enhanced version of the unshielded twisted cable in that it uses metallic foil for wrapping each of the pair and then a metallic braid to wrap all the four pairs together. Double-wrap is intended to make digital signal transfer safe from various types of hazards like interference of electromagnetic radiation. This network cable also suspends noise phenomena like crosstalk. However, this cable is very difficult to install because it comes with only two twisted pairs. Though it allows a network engineer to install it with RJ connector or STP connector, the installation process needs to be very careful to ensure that the metallic shields are not affected.
Crossover cable: Crossover cable alternatively called cross wired cable saves the cost of installing hubs or switches or even routers while connecting two computing devices. One end of the cable shows the switch with paired wires colored green and orange. This network cable is ideal for joining two PCs. However, in complex networks, this cable has limited use.
Stranded cable: This category of network cable is developed by blanketing a host of thin copper wires altogether. Stranded cables are best used in an environment where plugging, unplugging, installation are quite regular. Though stranded cables are very easy to bend, twist and flex, signal transmission never gets corrupted or lost.
Solid cable: This cable is mostly used in structured wiring because unlike the multiple thin wires in stranded cable, solid cable uses thick copper wires. Because solid cable has a single conductor, it can be utilized in insulation displacement connector too.
