Fibre Optics
The installation and termination of optical fibers used to be regarded as somewhat of a ‘Black Art’ but with standardization and easier terminating techniques this is no longer true. A basic knowledge of the subject, together with a quick lesson and some practice can get you started in fibre optics, but to really understand the subject and gain full in-depth knowledge will require some formal training.
There are lots of Fibre Optic training companies offering recognized qualifications and a quick search on the net should find one in your area.
If you are in the UK, Optical Technology Training Ltd offer several different courses to choose from including a City & Guilds qualification.
There are also hundreds of books on fibre optics and a search on the Barnes and Noble web site will find nearly 600 titles. Without reviewing them all it is difficult to know what to recommend, but two of the best sellers in this category seem to follow on quite nicely from this page without getting too involved with mathematics. The two books are the Introduction to Fibre-Optics by John Crisp and
Understanding Fiber Optics, Third Edition by Jeff Hecht.
Right, lets get on with the lesson
First a bit history
In 1870, John Tyndall demonstrated that light follows the curve of a stream of water pouring from a container, it was this simple principle that led to the study and development of applications for this phenomenon. John Logie Baird patented a method of transmitting light in a glass rod for use in an early colour TV, but the optical losses inherent in the materials at the time made it impractical to use.

NBN Co to provide fibre in greenfields
As suggested by the industry back in 2008, in late 2010 the government announced that NBN Co will be responsible for the installation of fibre in all new broadacre developments, estimated at 1.9 million premises over the next decade. NBN Co will also be responsible for all infill developments where it has fibre that is ready for service and capable of connection, and newly approved infill developments of 100 or more premises. NBN Co will most likely use contractors to dig the trenches and lay the cable.
For infill developments of less than 100 premises, Telstra will continue to be responsible for delivering infrastructure and services, using its copper infrastructure as interim solutions, pending rollout of the NBN. However, in these situations nothing prevents developers from requesting any provider (whether it be NBN Co, Telstra or some other provider) to service those estates.
Outstanding issues now are the potential cost of different pit and pipe standards as proposed by NBN Co which are more onerous than what the property industry is used to (ie. much more spatial requirements and expensive) and the lack of RF overlay.
The latter is a technology transition issue towards IPTV, however in the interim it prevents a capability that had the benefit to remove all of the unsightly TV antennas and dishes that ironically was a key benefit that attracted many developers to FTTH in the first place.

Coalition says Labor changing 98% broadband NBN promise
Opposition Shadow Minister for Communications, Senator Nick Minchin, has put out a statement claiming Australia’s Federal Labor Government is trying to change its promise to deliver fibre based broadband to 98% of Australians by using wireless from commercial operators instead.
Is Australia’s Rudd Labor Government taking Aussies for a ride when it comes to the Internet and broadband?
First we have a minimum 12Mbps fibre broadband guarantee that has seen delay after delay, with a 5 year build-out timeframe that hasn’t seen a single sod of soil turned, any contracts awarded and the removal of Australia’s dominant telco, Telstra, from the NBN (National Broadband Network) tender bidding process.
Then came the revelations that Australia’s new Government wants to censor the Internet, supposedly to protect Australians from child pornographers by blocking websites that pedophiles aren’t using in any case, preferring instead to operate via P2P and other more secretive channels. This then led the Government to announce it would trial the filtering of P2P services as well.
What type of phone systems do you require for office and business purpose?
Many business organizations have required robust phone systems that place main features voice mail, call forwarding or mailboxes. They are buying business through the help of scalable phone systems that can found as small as four phone lines and manufacture with your business to up to 250 extensions.
