Claim 6:
7. The wavelength selective switch of claim 6, wherein a dual-core spacing d in any one of the dual-core optical fibers meets a following formula:, ϕ
     l
    
    =
    
     
      
       f
       l
      
      ·
      λ
     
     
      π
      ·
      
       ϕ
       0
      
     
    
   
   ;
  
  ,
 

where fl is a focal length of the lens; fx is a focal length of the switching direction focusing module; D is a spacing between the different spectral band regions; and a ratio of the D to a light spot diameter φwx corresponding to the sub-signal after being performed direction switching via the switching direction focusing module is greater than a second set threshold.
