Patent ID: 11899244
Assignee: ACCELINK TECHNOLOGIES CO., LTD.
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 1:
2. The wavelength selective switch of claim 1, wherein the optical signal processing device comprises:
a lens array, comprising a plurality of lenses arranged in parallel, one of which is located at a rear end of the one dual-core optical fiber and is used for symmetrically outputting the two optical signals output by the corresponding dual-core optical fiber with a central axis of the lens as a symmetry axis;
a beam expanding module, which is located at a rear end of the lens array, and is used for respectively performing beam expanding on the optical signals separated from each other by the lenses;
a dispersion module, which is located at a rear end of the beam expanding module, and is used for dispersing a same optical signal after being beam expanded by the beam expanding module into the sub-signals with different wavelengths; wherein the sub-signals with different wavelengths are projected to the different spectral band regions.
