  • GigaPON is based on passive optical technology (1.25 GBit/s symmetrical) ;

it can be seen as an upgrade for a BPON which is standardised up to 622 Mbit/s.

  • The system will be packet oriented with a mixture of real-time and non-real

time data in an IP dominated world. A GigaPON system that combines high transmission efficiency with a guaranteed level of QoS clearly represents a competitive opportunity.

  • The main technical issues are found in the upstream link, from the user side

(ONU) to the network side (LT).
