Technology

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
