Cable Internet access

Written By: Gerald Kamau

In the telecommunications dynasty, there are two solitary Internet access methods. This includes the cabled and wireless Internet access means. However, the dominant means includes the cabled Internet access, as there is no environment that can exist absolutely without the use of cable. It is also referred to as bounded media of transmission. It involves the physical connection of telecommunication devices from the Internet service provider to the devices on the end user terminal.

With cable Internet access, a device known as modem is used to transfer data signal from the computer on the Internet Service Provider (source) through the cable to the client’s computer. This device converts the digital signals from source computer to analogue signals that can easily be transferred on a cable through a process termed as modulation. On receiving the signal on the client’s terminal, the modem converts the analogue signal on the cable to a digital signal through a process called demodulation.

When using bounded transmission media to access the Internet, either of the following types of cables can be applied. This includes the two-wire line cable, twisted wire cable, coaxial cable, or fiber optic cable. The two-wire line cable consists of two insulated copper wires that are separated by plastic insulator that reduces interline interface between the two. This wire is mostly used to transfer voice signals. A twisted pair cable that comprises of two wounded solid copper wires around each other and is mostly used to transfer both the voice signals and the data signals. The wounding prevents the development of an electromagnetic field around the two wires as they transmit the data. The fiber optic cable utilizes light and its phenomenon to transfer data from the source to the destination. The electronic signals from the sources are converted to light signals, and then propagated along the fiber optic cable.

A number of merits have been observed from the families, individuals, and enterprises that have opted to cable as a means of accessing the Internet. For instance, it is easy to set up cable connection environment. It is palpable that cable connection provides the highest connection speed with some types of cables supporting a bandwidth of 60 Gigabits per second (Gbps). The connection speed is assured irrespective of the solid distance differences between the Internet Service Provider and the end user terminal. It is also guarantee as the most convenient option to use, as one is always connected to the Internet. The means is not affected by weather conditions like cloudiness and rains, which might hinder other means of Internet access. In addition, once the cable system malfunctions, it is easy to identify the affected point, thus requiring only a simple repairing method.

On the other hand, the cabled Internet access is faced with minor hitches. The option is expensive when used between places located far from each other. For instance, connection between continents may be too expensive or impossible to achieve. As the distance increases, the level of attenuation of transmitted signals increases. This transmission impairment causes delivery of signals that are deviate from the original sent data, hence the delivery of distorted signals.
