The FTTH services are being launched over Overlay Access Network (OAN) rolled out by BSNL in major cities. Since the bandwidth availability at the customer’s end in FTTH will be huge, many high bandwidth services can be launched.
1.2 The technologies behind FTTH network are GPON and GE-PON. In GPON, subscriber end termination is on ONT (Optical Network Termination) unit. These ONT are having 4 Ethernet ports and 2 POTs (RJ11 ports). There is another category of ONTs which can support video overlay services (Analog TV) without Set Top Box along with above ports.
1.3 Many Next Generation Play services such as Voice (POTS as well as VoIP), High Speed Internet, IPTV, Cable TV (Analog), Video on Demand, Gaming, Layer 2 and 3 VPN, etc, can be provided on the FTTH-GPON, however, initially FTTH is being launched with the Broadband Internet Service, tariff for which is given last of BROADBAND TARIFF page
2.1 Since FTTH network can support higher bandwidth, many high speed Broadband plans are being offered to the customers on FTTH so as to give them a better experience and a differentiated product. Further, the rollout of FTTH will be in both residential as well as in commercial areas and hence the product is both for home as well as for business users.
FTTH
The telecommunications industry differentiates between several distinct configurations. The terms in most widespread use today are:
* FTTN – Fiber-to-the-node – fiber is terminated in a street cabinet up to several kilometers away from the customer premises, with the final connection being copper.
* FTTC – Fiber-to-the-cabinet or fiber-to-the-curb – this is very similar to FTTN, but the street cabinet is closer to the user’s premises; typically within 300m.
* FTTB – Fiber-to-the-building or Fiber-to-the-basement – fiber reaches the boundary of the building, such as the basement in a multi-dwelling unit, with the final connection to the individual living space being made via alternative means.
* FTTH – Fiber-to-the-home – fiber reaches the boundary of the living space, such as a box on the outside wall of a home.
* FTTP – Fiber-to-the premises – this term is used in several contexts: as a blanket term for both FTTH and FTTB, or where the fiber network includes both homes and small businesses. Diagram in the left can explained the concept.
Fiber is often said to be ‘future proof’ because the speed of the broadband connection is usually limited by the terminal equipment rather than the fiber itself, permitting at least some speed improvements by equipment upgrades before the fiber itself must be upgraded.
However there is a caveat,It is expensive to get good returns,and if the optical cable are damaged(as regularly happened now by the rival ISP) or any other case, then it cannpot be replaced..
At present BSNL is giving FTTH connection within the 1 K>M radius of its Telephone Exchange, to the Business houses which need connections to their system not less than 50 or the members of Apartment which has more than 50 units with them.
