A cascade add/drop transceiver (CAT) structure in a star-ring architecture for subcarrier-multiplexed passive optical networks (SCM–PONs) is demonstrated to overcome the optical beat interference (OBI) problem. The proposed CAT structure is a simple, reliable, and feasible approach for SCM–PONs. Our experimental results reveal that the CAT structure in a ring can completely eliminate the OBI problem, and maintain a good transmission quality.
