Method for producing an optical splitter cascade and optical assembly

A method for producing a splitter cascade formed of a plurality of optical assemblies, each including a respective optical component, the method which comprises:

• in a first step, forming a plurality of optical components in the form of splitters on a common wafer, each splitter having an optical conductor track pattern that opens out on a connection side and having at least one conductor track which splits into a plurality of output-side conductor tracks;
• in a second step, coupling optical fibers to the respective optical conductor track pattern simultaneously at a plurality of the splitters;
• and
• subsequently separating the individual components with the coupled optical fibers from one another;
• connecting a plurality of splitters to form a splitter cascade, wherein the conductor track patterns are formed such that the splitters of the splitter cascade each have an input, a plurality of consumer outputs and a loop-through output, except for a last splitter of the splitter cascade only having the consumer outputs, and such that a same optical intensity is present at all consumer outputs of the splitter cascade during operation, the optical intensity being lower than the respective intensity at the loop-through output, and/or that the total intensity provided at the consumer outputs of each splitter is identical, a respective loop-through output being connected to the input of a subsequent splitter.
