Embodiment 1
[0067] see image 3 , this embodiment 1 is a simplified structure, in embodiment 1, N=2, k=3. In other words, both the switching unit A and the switching unit C are 2×2 small optical switches, and the switching unit B is a 3×3 small optical switch. Its connection mode and control principle have been described in detail above, and will not be repeated here. And by image 3 It can be seen that in Embodiment 1, seven small optical switches (2×2 and 3×3 specifications) are used to form a multi-level optical switch array that can be expanded from 2×2 to 6×6.
Embodiment 2
[0069] see Figure 4 , this embodiment 2 is another simplified structure, in embodiment 2, k=2. In other words, the switching unit B uses 2×2 small optical switches. Its connection mode and control principle have been described in detail above, and will not be repeated here. And by Figure 4 It can be seen that in Embodiment 2, a large (2N×2N specification) non-blocking expandable multi-stage optical switch array is formed based on small optical switches (2×2 and N×N specifications).
[0070] It can be known from the above technical solution that in the multi-stage optical switch array provided by the present invention, the specifications of the switching unit A and the switching unit C are the same, and the entire switch array has a modular structure. In the early stage of network construction, the scalable scale of the entire switch array is determined by selecting the specification of switching unit B, and the number of switching units A and C required by the existing sw...
