Title:
OPTICAL SPLITTING APPARATUS, CHIP, ODN, AND PON SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/032238
Kind Code:
A1
Abstract:
The present application provides an optical splitting apparatus, a chip, an ODN, and a PON system, which are used for achieving a plurality of optical splitting ratios via the same optical splitter, can be applied to scenarios having various optical splitting ratio requirements, and are broadly applicable. The optical splitter comprises: a plurality of light inlets, a first optical splitting unit and a second optical splitting unit, the first optical splitting unit comprising a plurality of optical splitters connected in parallel, and the plurality of light inlets being respectively connected to the input ends of the plurality of optical splitters in the first optical splitting unit; a first optical splitter and a second optical splitter included in the plurality of optical splitters, the first optical splitter and the second optical splitter having different optical splitting ratios; a first output end of the first optical splitter being connected to a first input end of the second optical splitting unit, at least one output end of the second optical splitter being connected to a second input end of the second optical splitting unit, and the second optical splitting unit being used for splitting and then outputting optical signals from the first input end and the second input end.
