Technical field
The utility model relates to a kind of photoswitch, is specifically related to a kind of cascade 1 * 8 photoswitch.
Background technology
Photoswitch is a kind of important optical passive component, and it carries out the selective switch operation to light signal in optical network system.In arbitrary communication network, current channel all will carry out channel route or conversion between each node, so a kind of desirable photoswitch is very necessary.
Traditional cascade 1 * 8 photoswitch, as shown in Figure 1, the elementary cell composition that comprises housing and be arranged on enclosure interior, its elementary cell is mainly formed by 71 * 2 identical photoswitch cascades.Promptly 2 of the one 1 * 2 photoswitch output terminals link to each other with the input end of the 21 * 2 photoswitch and the 31 * 2 photoswitch respectively; 2 output terminals of the 21 * 2 photoswitch link to each other with the input end of the 41 * 2 photoswitch and the 51 * 2 photoswitch; 2 output terminals of the 31 * 2 photoswitch link to each other with the input end of the 61 * 2 photoswitch and the 71 * 2 photoswitch.The input end of the one 1 * 2 photoswitch forms the input end of 1 * 8 photoswitch, and the output terminal of the 4th, the 5th, the 6th and the 71 * 2 photoswitch forms the output terminal of 1 * 8 photoswitch.1 * 8 photoswitch of said structure forms owing to having used more light path switching device to integrate, so its complex structure, and volume is big, and cost is high, and integrated level is low, and of paramount importance is that optical stability is low.
The utility model content
The utility model technical matters to be solved provides a kind of compact conformation and high a kind of cascade 1 * 8 photoswitch of optical stability.
For addressing the above problem; A kind of cascade 1 * 8 photoswitch that the utility model designed; The elementary cell that comprises housing and be arranged on enclosure interior, wherein the input end of elementary cell and output terminal are drawn to form the input end and the output terminal of this cascade 1 * 8 photoswitch from enclosure interior.Said elementary cell mainly is made up of 11 * 2 photoswitch and 3 D1 * 2 photoswitches.2 output terminals of above-mentioned 1 * 2 photoswitch link to each other with 2 input ends of a D1 * 2 photoswitches; Wherein 2 input ends of the one D1 * 2 photoswitches are connected with 2 input ends of the 2nd D1 * 2 photoswitches, and other 2 input ends of a D1 * 2 photoswitches are connected with 2 input ends of the 3rd D1 * 2 photoswitches; The input end of 1 * 2 photoswitch form elementary cell 1 input end, the output terminal of the 2nd D1 * 2 photoswitches and the 3rd D1 * 2 photoswitches forms 8 output terminals of elementary cell.
In the such scheme, 1 input end and 8 output terminals of said elementary cell are preferably drawn from the same side of housing.
In the such scheme, the structure of said 3 D1 * 2 photoswitches is preferably in full accord.
Compared with prior art; The utility model adopts 11 * 2 photoswitch and 3 D1 * 2 photoswitches to be cascaded into 1 * 8 photoswitch, because the minimizing of light path switching device makes that not only the volume of the utility model reduces, cost reduces, is convenient to the integrated of system; And can reduce the degree of freedom that influences stability of layout; Reduce the light path debugging difficulty, improved the switch corresponding speed, improved optical stability.
