The pigtail has a first waveguide and a second waveguide. The first waveguide transmits incident light, and the second waveguide receives the returned light. The pigtail is attached to one side of the space, and the lens is attached to another side of the space. Moreover, the cap includes a hollow portion, a first connecting portion and a second connecting portion. The lens is placed inside the hollow portion, and the space is connected to the first connecting portion of the cap."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Variable optical attenuator","description":"Provided is a variable optical attenuator, including a pigtail, a spacer, a lens and a cap.
