To many of us, these are simply different terms for the wired black box we need to connect our devices to the internet.

Optical fibres offer more reliable transmission, free from data lossĪs fibre optic networks are installed in more locations, fibre modems are increasingly preferred by commercial and home internet users.Fibre is a faster, more efficient option than both traditional phone lines and coaxial cabling, offering high-speed, gigabit internet connectivity.A single optical fibre can carry as much information as thousands of copper wires.There are three main reasons why telecommunications networks are upgrading to fibre optics: While traditional copper wire transmits data by electrical impulses, fibre optic cable is made from fine glass fibres which carry light impulses transmitted by an LED or laser. Since the first telegraph cables were laid over a hundred years ago, telecommunications infrastructures have relied predominantly on copper wires to transmit electrical signals.

It works by using TV channel space for data transmission: certain channels are used for downstream and others for upstream transmission.īecause the coaxial cable used by cable TV provides much greater bandwidth than telephone lines, a cable modem can be used to achieve faster access to the web, offering improved connection speeds when compared to DSL.Īnother benefit of cable modem compared to DSL modem is that this can provide telephone, television, and internet access, under a single consolidated service contract. Just like with DSL, this has the advantage of a preexisting network of cables available for you to connect your modem to.Ī cable modem provides a broadband Internet connection over a cable TV coax. Because it uses higher frequency bands than the telephone system to transfer data, DSL service can be delivered simultaneously with wired telephone service over the same phone line.Īnother widely available option for internet connection is to use the same coaxial cables used to transmit television services. And since it piggy-backs the telephone network, there’s a pretty well-entrenched DSL infrastructure servicing most towns and cities.

Because of this, an ADSL modem is better for users who download more data than they upload.ĭSL-based internet connections have been around for a while.
This simply means that more of the line’s bandwidth is dedicated to downstream (download) data than upstream (upload) data. The most commonly utilised DSL technology for internet access is known as asymmetrical DSL (ADSL). DSLĭSL refers to a family of technologies that transmit digital data over phone lines. These correspond to the three most common types of internet connection: digital subscriber line (DSL), cable, and fibre optic. Typically, not including completely wireless options like mobile broadband, there are three main types of broadband modem you’ll encounter. It’s also responsible for converting incoming analogue signals into a digitally legible format-known as demodulating. This usually means converting computer data into a medium suitable for transmission, such as telephone lines or radio waves. Short for modulator-demodulator, a modem converts data between a digital and analogue signal to facilitate transmission. In the most common set-up, a modem acts as a bridge between your ISP’s infrastructure, be it metal cable, fibre optic, or satellite-based, and your ethernet cable output, into which you can plug a computer or WiFi router.
If you’ve ever been responsible for setting up an internet connection in your home or office, chances are you’ve encountered a modem-the piece of equipment that connects you to your Internet Service Provider’s (ISP) physical network. In this post, we’ll show you exactly how they work and their importance in all our daily lives. Modems are the hardware that connects us all to the internet. What Is a Modem?
