Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 2:
3. The wavelength selective switch of claim 2, wherein a ratio between a spacing of adjacent dual-core optical fibers in the fiber array and a light spot diameter φl of any one of the optical signals output via one of the lenses is greater than a first set threshold, and φl meets the following formula:, ϕ
    l
   
   =
   
    
     
      f
