To enable the SuperPON systems developed within the ACTS- PLANET (Photonic Local Access Network) project to meet the availability targets of the offered services redundant elements are provided to give protection in the event of failures. Using extensive reliability data a semiconductor optical amplifier based SuperPON architecture is evaluated in terms of availability. An amount of redundancy (mainly of optical amplifiers and of cable plant) is required to provide the availability for the system to support telephony in addition to the broadband service basket. Cable cut is seen to be a dominant factor. The telephony availability requirement can be achieved for the Fiber To The Home scenario with redundancy most importantly in the first distribution section and in the amplified splitter. The possible use of dual homing to counter catastrophic failures and the issues surrounding protection switching are also discussed.
