Paper Abstract

In this paper, a novel transmissive-reflective star coupler is proposed for expanding the scale of bidirectional WDM star networks. By combining appropriately the symmetrical transmissive property of conventional N+N passive star coupler with the reflective property of the reflective link, the transmissive-reflective star coupler is carried out. This coupler both reserves the advantages of the conventional reflective N-star coupler and overcomes its shortcomings to make the number of ports connected with nodes in the coupler be up to four times as many as that in the reflective N-star coupler. Besides, not only the bidirectional WDM star network constructed with the coupler has great flexibility of networking, but also its network scale can be expanded conveniently and smoothly on line. So, this WDM network can better satisfy the requirements of communication services at present and in future. At first, the structure of this transmissive-reflective star coupler is introduced. Next, its features are analyzed. Moreover, the required distribution ratios of power splitters in this star coupler are computed. Furthermore, the required gains and output power of optical amplifiers in this star coupler is referred. Finally, a conclusion about the star coupler is given.
