Abstract

An apparatus and method for cost effectively providing protection in a PON. Protection ports usually on a protection LT card are configured to communicate with a selectable one of the downstream ODN splitter/combiners associated with the primary ports on the remaining LT cards of the OLT. Each protection port includes at least a splitter for distributing a transmitted signal from a light source to a plurality of switched protection fibers and may have an optical amplifier to provide for lossless or low loss distribution. Each port may also have a combiner for combining received signals from a plurality of switched protection fibers. When a failure is detected at a primary port traffic is re directed from the primary port to the protection port after the protection port has been configured to communicate with the same ODN splitter/combiner as the failed primary port.
