TeraGo Networks Presents: Back to Basics – How Fibre Works

Businesses are on the lookout for technologies that are capable of providing a high speed Internet connection. The faster the connection, the faster a company’s employees can work, and as we’re all aware – time is money. Having the capability to perform at optimal efficiency levels is essential for businesses, and high speed Internet provides companies with the capability to conduct their Internet based operations at an increased rate. Fibre is one of the ways in which businesses can obtain a high speed connection, but how does fibre actually work? What makes it so fast? And if it’s so great – why doesn’t every company have a fibre Internet connection?

Fibre, or fibre optic, uses pulses of light to create an electromagnetic carrier wave that can be used to send data at very high speeds. Instead of using copper cables to transmit, fibre optics uses a medium called “fibre” to do the exact same thing with light. The light travels through the fibre-optic strands of optically pure lines to reach their destination. To break this process down into steps:

·         The optical signal is created by a transmitter

·         The signal then travels along the fibre optic cable

·         Once the signal is received, it is turned into an electrical signal that passes through to the receiver’s device

Fibre is capable of transmitting data at high speeds because it has a higher frequency range. When data is transferred over a wire line service, the throughput of data is determined by the frequency range that a cable will carry. The higher the frequency range the greater the bandwidth – and the more data that can be put through per unit time. In comparison to copper lines, fibre technology is far less susceptible to noise and electromagnetic interference. For example, if you were to transmit data over 300 kilometers on a fibre line the signal wouldn’t experience any real loss of quality, while a copper line typically suffers a great deal of degradation over such a long distance.

Although fibre is capable of transmitting data over a vast distance without compromising quality, businesses are still looking to other technologies to support any long haul data transfers. This is because laying a fibre line from Toronto to Vancouver, for example, can be quite costly and time consuming. Many companies choose to utilize other methods, such as fixed wireless radio technology, to send their data over greater distances. Adopting a hybrid model, such as fibre and fixed wireless, can be very efficient and save on costs.
