List of the 1562 Active Gram Panchayats as on 18.05.2015 under NOFN has been uploaded on BBNL website. List of the active Gram Panchayats can be seen by clicking the link 'Active GPs' on the home page of www.bbnl.nic.in.
In NOFN the technology called GPON (Gigabit Passive Optical Network Technology) will be utilised.
A passive optical network (PON) is a network architecture that brings fiber cabling and signals to the home using a point-to-multipoint scheme that enables a single optical fiber to serve multiple premises. Encryption maintains data security in this shared environment. The architecture uses passive (unpowered) optical splitters, reducing the cost of equipment compared to point-to-point architectures.
The GPON (gigabit passive optical network) standard differs from other PON standards in that it achieves higher bandwidth and higher efficiency using larger, variable-length packets. GPON offers efficient packaging of user traffic, with frame segmentation allowing higher quality of service (QoS) for delay-sensitive voice and video communications traffic.
The main components of GPON technology are OLT, ONT/ONU, Splitters, OF cables etc.
ITU standard G-984 series as well as TEC spec GR no.PON-01/02 Apr 2008 define GPON technology
