New transmissive as well as reflective star couplers are proposed with the property that networks based on these stars can be interconnected without problems. The new star couplers are generated by minor modifications of conventional star couplers. Besides optical amplifiers only one additional special star coupler is necessary. The interconnection scheme allows simple addition of redundancy.
