Abstract
The invention relates to a method for performing a switch operation between a first Optical Line Terminal OLT and a second OLT in a Passive Optical Network PON, said first and second OLTs being connected to a plurality of Optical Network Units ONUs through at least one splitter. The invention enables to avoid the detection of a timestamp drift error during protection switching operation by modifying the threshold of the detection in the second OLT.
