Assume a Full-Service STOLAS network with
aggregated traffic inputs. Create a realistic

• 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).

•A management architecture for flow based IP
services across core, and multiple access domains
has been developed and tested for different QoS.
•A novel time-and-wavelength MAC protocol for
packet-based access networks has been designed.
An implementation in an emulator for real data
traffic will be used for the field trial.
