Traditional ADSL suffered from the last mile connection problem and speed and bandwith is mainly depend on the distance of customer premises to the exchange, and other factors..you know light is traveling fastest anything in the earth.. so Fibre Obtical cables are used for signaling.. and the technology employed here is FTTP or FTTH although the protocols is different from many country and still in early stages..A central server located in a central office is directly connected to the subsvribers premises / offices directly by fibre optical networks get 500 Mbps maximum ( some body disagree that it is actually 100 mbps).. This scheme is useful to the large multisorey buildings/ housing boards/ offices/ where one of them connected then distributed among themselves.. so after distribution among the members of premises the speed may be proportutionate to the number of distribution...
This is only as a testing stage and unlike ADSL which has distance limitation ..this technology support atleast 80k.m length distance without losing the speed..
It is not impossible in India, if any ISP want to deploy it...See some example of Asian countries that deployed this technology and the cost factors.
Indonesia
Biznet Networks is one of the leading network providers in Indonesia. Being the first one who deployed this service in South East Asia, Biznet Metro FTTH network uses the latest Gigabit Ethernet Passive Optical Network (GE-PON) based networking technology. Supported by Nokia Siemens, this network is capable on delivering Triple Play services that consist of Data (Internet or Intranet), Voice (VoIP) and Video (Interactive TV and Multimedia) in a single infrastructure. This network is capable of supporting up to 1 Gbyte/s data transfer. First Media, a company born from Lippo group's new $650 million investment in Internet in Indonesia, as well as cable television, began offering FTTH (using coaxial cable not Optical Fiber), branded as FastNet, on 8th of September. Plans offered are: 384 kbit/s for $11/month, 512 kbit/s for $22/month, 784 kbit/s for $33/month, 1.5 Mbit/s for $66/month and 3 Mbit/s for $132/month. Every plan comes with unlimited usage and all speeds cited are downstream, upload speed is not specified by First Media. These plans are the most competitive plans to be offered in Indonesia, to this moment.
Hong Kong
As of April 2006, HKBN was offering its customers Internet access via Fiber to the Building and Fiber to the Home. Speeds ranged from 10 Mbit/s (19 USD/month) to up to 1000 Mbit/s (1 Gbit/s) (215 USD/month), although the speed to non-Hong Kong destinations was capped at 20 Mbit/s. HKBN also provided FTTH plans for speeds of up to BB100 (100/100 Mbit/s) and BB25 (25/25 Mbit/s), for approximately US$25 and US$22 monthly. And in October 2007, largest telecom gaint in Hong Kong -- PCCW start to offer both 100Mbps and 1000Mbps FTTH internet plan for consumers. As Nov. 2007, their cost is around USD75 and USD280 respectively without any speed cap on overseas traffics.
Japan
FTTP, often called FTTH in Japan, was first introduced in 1999, and did not become a large player until 2001. In 2003-2004, FTTH grew at a remarkable rate, while DSL's growth slowed. 10.5 million FTTH connections are reported as of September 2007 in Japan.[2] Currently, many people are switching from DSL to FTTH, the use of DSL is decreasing, with the peak of DSL usage being March 2006.
Average real-world speed of FTTH is 66 Mbit/s in the whole of Japan, and 78 Mbit/s in Tokyo.
FTTH first started with 10 Mbit/s (at end-user rate) passive optical network (PON) by Nippon Telegraph and Telephone (NTT), and 100 Mbit/s (at end-user rate) with GEPON (Gigabit Ethernet-PON) or broadband PON is major one in 2006. PON is major system for FTTH by NTT, but some competitive services present 1 Gbit/s (at end-user rate) with SS (Single Star). Currently, most people use 100 Mbit/s.
Major application services on fibers are voice over IP, video-IP telephony, IPTV (IP television), IPv6 services and so on.
South Korea
FTTP is offered by various Internet service providers including KT (formerly, Korea Telecom), Hanaro Telecom, and LG Powercom. The connection speed for both downloading and uploading is set to be 100 Mbit/s. Monthly subscription fee ranges between USD30 and USD35.
Pakistan
Islamabad, Pakistan's capital city, got its first passive optical network in April, 2006. Nayatel was Pakistan's first broadband provider to offer triple play services (voice, video and data) over BPON. As of April 2007, Nayatel offered Analog Video which was carried as overlay on fiber optic using the 1550 nm wavelength. The video headend was supplied by Scientific Atlanta and the voice network was powered by an Alcatel softswitch.
Nayatel is one of the companies in Pakistan who have invested in broadband infrastructure development in Pakistan. The infrastructure is reliable, and meets the current and future broadband needs of the corporates and home users in Pakistan. The Nayatel FTTH is providing basis for providing a long term solution for data, voice and video (triple play) needs of Islamabad community for todays and future.
WorldCall, is a Pakistani company with existing footprint in Karachi and Lahore. WorldCall was awarded a contract from Islamabad's Capital Development Authority (CDA) to lay down telecom ducts along the roadside.
