High splitting, optically amplified, passive optical networks (SuperPONs) are investigated in terms of redundancy provision and protection mechanisms. Options for redundancy, including the important special case of dual homing, are detailed, and it is determined as to which of these options (duplication of the feeder and first distribution section, and N+1 protection of the optical amplifiers in the amplified splitter) would be required to be provided to all attached users to facilitate appropriate availability of the basic telephony service. The distributed amplified splitter dual homing solution is found to outperform the single amplified splitter solution in terms of its survivability. The protection mechanisms necessary to automatically switch to the redundant provision are discussed and it is seen that with the aid of suitable regular precautionary procedures protection switching can generally be provided rapidly (<50 ms). Finally, an availability, and cost versus availability, study confirms the aforementioned redundancy assessment for fiber-to-the-home (FTTH) implementations, but shows fiber-to-the-curb (FTTC) as needing additional redundancy.

The generic architecture of a SuperPON (super passive optical network) with a target optical split of 2048 and a maximum range of 100 km. A bit rate of 2.5 Gbit/s is distributed to the optical network units (ONU) by time-division multiplexing (TDM) in the downstream direction, whereas a time-division multiple access (TDMA) protocol is used to share the 311-Mbit/s upstream bit rate. Optical repeater units (ORUs) are integrated in the network to compensate for the optical losses.

The paper presents evaluation results of the SuperPON demonstrator. It shows the feasibility of a passive optical network with increased bit rate (2.5 Gbit/s downstream and 311 Mbit/s upstream), extended range (100 km) and enlarged splitting factor (2048).
