Definitions
- Optical routers are an important part of optical interconnect technology. They can connect the transmitting/receiving nodes and transmit the optical signals sent by the transmitting nodes to the receiving nodes accurately. Optical routers can be divided into space routers based on spatial optical switches and wavelength routers based on wavelength optical switches. Wavelength routers can achieve self-routing of light because they do not require dynamic adjustment. . The optical router based on the wavelength cross filter can effectively reduce the number of switching nodes in the optical wavelength router and reduce the router size and delay by utilizing the periodic characteristics of the wavelength cross filter filtering spectrum.
- each 2X2 wavelength switch ⁇ ⁇ includes two input terminals and two output terminals (input 1 and input 2, output 1 and output 2 as shown in FIG. 4), and the input stage includes 2 ⁇ .
- Input ports such as the input port L of the input stage in Figure 3.
- Ml and M2 are the number of input ports in the input stage or the number of output ports in the output stage.
- Ml and M2 are the number of input ports in the input stage or the number of output ports in the output stage.
- Ml and M2 are the number of input ports in the input stage or the number of output ports in the output stage.
- Ml and M2 are the number of input ports in the input stage or the number of output ports in the output stage.
- the number of input ports in the input stage is 8, so the total number of 2X2 wavelength switches in the 8X8 routing device is 12, and the number of 2 X2 wavelength switches passing from the node T ⁇ to the node R 8 is 3.
- the 2 ⁇ 2 wavelength switches required by the present invention are 32, and the 2X passes.
