PROBLEM TO BE SOLVED: To provide a waveguide type wavelength-depended multiplexing- branching filter in which coated optical fibers of single core can be obtained from a package without using a fan-out device or the like and free routing in the package is possible, for example, for odd-numbered channels and even- numbered channels. respectively. SOLUTION: A waveguide type wavelength-depended multiplexing-branching filter is a wavelength-depended multiplexing-branching filter and stored in a package 4 where the single-core optical fiber 6 is aligned and connected with a waveguide of the optical waveguide element 1, and the multi-core ribbon fiber wire 8 is optically aligned and connected with the other waveguide of the above optical waveguide element 1 via the multi-core optical fiber array 7. In this case, the multi-core ribbon-coated fiber wire 8 is separated into the single-core optical fibers 12 in the package, and the each terminal of the separated optical fibers 12 is taken out of the package 4 and terminated. |
