In many countries, the Philippines for example, a digital subscriber line (DSL) is sometimes deemed more expensive than getting a broadband. The reason for this is that in the Philippines, when people mention “DSL” it is automatically associated with an Internet Connection plus a telephone line. And it not entirely wrong, because that is what a DSL truly is. But in the same country, when people mention “Broadband”, most of them are referring to stick-like devices which can be attached to a universal serial bus (USB) port and can be pre-loaded to access the internet. What’s more is that there are promo’s from different telecommunication companies convincing the consumers to try a broadband because they can have unlimited surfing hours with their chosen day, within their budget. It somehow gives the consumers a more “sense of control” rather than having an all-day, all-night access to the internet. For a DSL line, most providers also require a “bond” or a holding period whereas the broadband stick only requires a one-time purchase and enough credits to pump it. This is how people normally view a broadband. But let’s take a deeper look at what’s broadband is made of.

Broadband, Defined

The term broadband actually refers to that wide bandwidth diagnostics of a transmission intermediate and its capacity to convey multiple signals and traffic types all at the same time. The medium can be a coax, the more technologically advanced optical fiber, or at least a twisted pair or even wireless. In contrast, nevertheless, a “base-band” describes it as a communication system in which the information is transported across a single channel.

Types Of Medium

A Coax is a type of cable which has an “inner conductor” that is normally surrounded by a tubular insulating layer, a sheath or at times, a jacket. Likewise, a good number of coaxial cables also have an insulating outer geometric axis. A coaxial cable was invented by an English engineer and mathematician named Oliver Heaviside, who had the design patented in the year 1880.

Coaxial Cable Vs. Other Shielded Cable

A coaxial cable differs from those other shielded cable which are used for carrying lower-frequency signals, such as audio signals, in such a way that the dimensions of the coaxial cable are controlled to give a a specific, meticulous, constant conductor spacing, which is needed so that it can function efficiently like that of a radio frequency transmission line.

Optical Fiber
The optical fiber also known as optical fibre is more of a flexible, transparent fiber which is made from high quality squeeze out glass or silica, or a plastic, which is by description, only slightly thicker than the human hair.

Twisted Pair
A twisted pair, on the other hand is a type of cabling in which two conductors of a single conductor are “twisted” together to eliminate electromagnetic interference from external sources.

From the word itself, it does not make use of an electric conductor because it makes use of radio waves instead.

So, from where does a broadband stem? There are four to choose from.
