ABSTRACT:
A passive optical network suitable for use as a telecommunications access network, having a head-end transmitting in a first optical frequency and one or more subscriber stations transmitting on a second common optical frequency. A carrier sense, multiple access protocol, with collision detection, is used, the collision detection being performed in the subscriber and head-end stations.
