The fibre optical is “fashion” and continues to appear in national and international newspapers. The governments of all nations recognize the need to deploy fibre optic networks to improve the competitiveness of their economies. Despite the economic crisis, the major telecom operators in the world, along with municipalities, electric and even builders have started at a lower or higher rate depending on the country, the deployment of fibre optics access networks. According to the OECD (Organization for Economic Cooperation and Development) in June 2009, the number of broadband users in the world was 271 million, employing around 9% of them FTTx fiber optic connections. However, penetration is very disproportionate countries. Thus, for example, 51% of broadband connections in Japan are fiber connections. Other leading countries are South Korea with 46%, Sweden and Slovakia with 21%, and Denmark and Norway with 10%. The reality is that usually the construction of fibre networks will create many jobs, help improve our productivity, quality of life and energy efficiency.
Traditionally, the main drawback of the optical fiber was its price, however, today the economies of scale and experience, have allowed the economic viability of the fiber and optical components a reality. While laying fiber to the home can make a large initial investment in civil works and fiber (CAPEX), it may be quickly repaid through reduced maintenance costs (OPEX) compared to current copper infrastructure and higher revenues for new services that may be offered.
The acronym FTTx is widely known as Fibre-to-the-x, where x may denote different destinations. The most important are:
FTTH (home): In FTTH or fiber to the home – fiber reaches the inside or front of the same subscriber’s home or office.
FTTB (building): In FTTB or fiber to the building – before the fiber ends, typically at a point intermediate distribution inside the building or vicinity of subscribers. From this intermediate distribution point, subscribers can access late or house building through VDSL2 (Very high bit-rate Digital Subscriber Line 2) technology on copper pair or Gigabit Ethernet over twisted pair CAT5. Thus, the fiber laying can be progressive, in less time and at lower cost, reusing the subscriber’s infrastructure.
FTTN (node or neighborhood): In FTTN or fiber to the neighborhood, the fiber ends farther FTTH subscribers and FTTB, typically in the immediate neighborhood.
There are several technological solutions to offer FTTx. These options are usually divided into two broad categories: PON (Passive Optical Networks), which do not require active electronics between the end user and the central operator, and ASON (Active Optical Network), which are installed between the active electronic components end user and the central operator. The technologies PON (Passive Optical Networks) and especially GPON (Gigabit PON), are what have attracted more attention because it does not require electronic or optoelectronic devices active for the connection between the subscriber and exchange, involving investment and maintenance costs considerably less than the ASON technology.
This is a short video about the NBN, what it is, how it is developing, and where it could go. This is not meant to be a comprehensive video, but an introduction for educational purposes that will hopefully stimulate further discussion.
What people are saying about the fibre broadband in the cyberspace:
The advantages of fiber optics are many: higher bandwidth, longer distances from the central office to the subscriber, absence of electromagnetic interference, safety, ease of installation, etc.. Furthermore, the reduction of repeaters and other devices entail lower initial investment, lower power consumption, less space, less points of failure, etc..
The fibre broadband will provide significant benefits to users of the digital home. In addition it will allow access to more and better services (gaming, content sharing, remote control home devices, IP video conferencing, telecommuting, telemedicine, teleCARE, etc..) Pleasures of a variety of devices through DLNA protocol (Digital Living Network Alliance ) one another – and at the same time connected to the Internet, without reducing the bandwidth or quality. Significantly increase upstream bandwidth than copper technology symmetry allows for example access video recorded by high-definition IP cameras at a higher rate than other technologies. Optical fibre is also the only medium capable of supporting IPTV offers a really attractive to users with the advantages of DTT (Digital Terrestrial Television) or satellite television.
Siliconrepublic.comEircom launches fibre broadband productsRTE.ieThe move has been welcomed by broadband lobby group Ireland Offline as “probably the best thing that has happened in Ireland in many years”, as good broadband provision is an enabler of economic growth.
High-speed fibre broadband is now available to thousands of homes and businesses across Burnham-On-Sea, BT announced on Wednesday. More than 4,000 households and firms in the town now have access and this will soon increase to more than 10,500 premises as engineers complete the upgrade in the coming weeks.
Initial prices released for FTTP On Demand show that upgrading an FTTC line to a faster FTTP (Fibre to the Premises) type connection isn’t going to be cheap. So a way in which customers could get FTTP-type speeds without necessarily forking out for a last mile upgrade is likely to be well received.
Fibre broadband requires a significant investment in the short term, it is also very beneficial to the operator. Most investments are for public works, however it can be reduced, depending on the country and the rules of network operators in terms of open (open access), overhead lines instead of underground fiber solution “blown” (fiber blow), insensitive fiber curvature solution (bend-sensitivity fiber, etc.).
Competition in telecommunications services continue to grow in the past and, therefore, the operator has some challenges to make your business successful and fiber optic broadband can help in all of them.
