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.

Conroy details NBN Co greenfield fibre role
The Federal Government has moved to further lock in the National Broadband Network (NBN), announcing that NBN Co will install fibre in new developments from 1 January 2011.
Under the arrangement, NBN Co will provide fibre to all broadacre developments, infill developments where the company already has NBN fibre in service and newly approved infill developments of 100 or more premises.
Telstra will be responsible for delivering infrastructure and services for infill developments of less than 100 premises.
The government has given NBN Co licence to carry out the connections itself or outsource under sub-contracting or build-operate-transfer arrangements.
NBN Co will also establish a panel of appropriately qualified and experienced providers who can bid to install fibre on its behalf.
According to the government, some 1.9 million new premises are expected to be built while the NBN is constructed.
