The research and scheme of 10G GPON technology

The system structure and working principle of 10G GPON is briefly introduced.Comparatively analyzed technical advantages of 10G GPON,and intensively investigated the system updating process of GPON to 10G GPON as well as the critical technology of symmetrical 10G GPON.At last a innovative scheme of 10G GPON was proposed.Thise schemes,which is compatible with the existing GPON,and with 10Gbps upstream and downstream.It provide a good referrence for future 10G GPON access network system.
