Abstract--The increasing amount of bandwidth requirements
and quality of service needs for the next-generation access
networks has boosted extensive research in the fiber-optics com-
munication field. In this light, passive optical networks (PONs)
combined with optical code division multiple access (OCDMA),
provide a potentially cost-effective solution to meet such band-
width demands. This work proposes an optical transparent
architecture which enables all-optical communication between
the network nodes. The encoded data streams are multiplexed
at a merging point which results in multiple user interference
(MUI), thus significantly reducing the network throughput. The
networking nodes are able to monitor and record user activity
in the PON, and further register the (past) state of activity
at the merging point. In this work, we study the coherence of
state between the networking nodes and the merging point, for
