Optic Fibre technology is the way to go for the National Broadband Network

When we look into the future, we see a clear difference. Individuals at that particular time will be interlinked with experts from every imaginable profession, having access to scientific and daily equipments all over the world, reaching societies of every shape and size, by employing different kinds of modern application and services- each and every one of them in real time.

Broadband will allow our small-scale projects in places such as tele-health, smart electricity division and control, distance educating and tele-operation industry to be embraced widely across our business and also social lives.

The only efficient way of accomplishing this kind of future is by fibre optic based infrastructure.


Long lasting and flexible

In addition to a significant upgrade in the connection speed, fire optic networks also provide a huge capacity to be at par with the modern technological advances. As well as a significant increase in connection speed, fibre optic networks offer a tremendous capacity to keep up with any new technological advances. The moment the key fibre optic infrastructure is in position, it is possible for it to be rearrange and the resultant electronics upgraded when crucial, to supply even a greater capacity. It is capable of doing this far more efficiently than present wireless or copper based systems.

With regard to its serviceable lifetime, the glass that is used in making fibre optic cable is durable, stronger than copper and capable of retaining its transmission properties after undergoing physical stress like weight strain or getting attacked by cockatoos and rats. Fibre is installed from copper; it is installed using coatings of good quality that are placed inside ducts and newer systems are encased completely by electrical transmission wires.

The pending question that still remains is that, are we able to be in the same level as other nations in the future by using our fibre optic network mean in supplying broadband of good quality.


Will we finally be as fast as Korea?

Earlier this year, the Korea Communications Commission broadcasted that they are going to be funding a network that is able of achieve on average one gigabit per second per user and the network can also give support to ultra high definition television. The network appears to have been designed to achieve high performance since it is ten times the figures that were put forth in our proposal.

It is reported that the technology intended for our National Broadband Network (NBN) is going to supply users with up to 100 megabits in every second, the real speed is dictated by the total users connected, the kind of service that is being accessed, the number of users who are sharing access and also intermediate paths (aggregation factors) at distinct points in the network and the congestion in external networks.

Our suggested network will likely be based on Passive Optical Network (PON) technology. Modern PON equipment is able to achieve speeds of around two gigabits in every second (i.e. 20 times faster than the best consumer broadband technology available in the contemporary world), and the speed remains similar regardless of it being deployed to Korea, Sweden or Australia. The equipment is constantly getting better; this makes the youngest network the fastest, as long as the aggregation factors are similar.

The topology and technology of the network are not the only factors that determine the connection speed. Distance also influences the connection speed, when signals are required to travel at a long distance they will take more time in arriving causing the signal to become dampened because of the long travel regardless of the medium it used in the travel even if it is through optic fibre. An example is Australians, living along the eastern seaboards, which are very spread out.

Our language is to blame for our online sluggishness Countries that do not have English as their national language form the group of high speed nations. This is due to the fact that majority of their content is stored locally. They include countries like: Sweden, Finland, South Korea and Norway. In Australia, a significant quantity of content that is stored abroad is accessed and it’s this international connection that will continue to be our biggest obstacle.


Why not wireless?

Even though there is some good wireless services available currently their limitation is that the moment they are deployed, the beams interfere with one another. Due to the interference small ‘slices’ of spectrum are warranted to every network provider. In the case of fibre we are capable of employing the whole transmissible spectrum since the light is enclosed within a cable. This simply means that we can be able to encode and send more data using the fibre optics and the efficient bandwidths are constantly going to be larger. This is not meant to point out wireless solutions as being poor, instead it is meant to show that they hold a position that complements the contribution of fibre optical systems.

Individuals who live a long distance from the exchanges will continue being served well by wireless since it is very expensive to install fibre and equipment so as to give a boost signals in the long distance. The advantages that this step will make are minimal if you compare it to the cost and also there are very few neighbors to share the cost with. Countries like Korea are also using this wireless technology for their remote areas.

The future still promises great advancement in wireless. Currently CSIRO holds the world record of wireless that is at 6Gbps faster than that of PON. However, the equivalent world record for fibre is at 100Gbps. It is however unfortunate that the mentioned holding speeds are still not found en massel.


Too ambitious?

Australia’s NBN is considered to be its first most ambitious infrastructure. This statement can only be proved by historians so it is up to them to decide if the claim is true or not. However, considering Australia’s size, the suggested network is absolutely exciting. It is only Canada which has the same area of land and extent of terrains, and there is no existence of the same projects there.

When Australia is compared to Korea- the broadband leader we find that Australia’s land mass is approximately 7.6 million square kilometers whereas that of South Korea is just 98,000 square kilometers and their population is twice that of Australia. This makes it very clear that the deployment equation is very distinct.
