Abstract
An optical module 31 is provided in which a wavelength division element 32 such as an optical multi-layer film or diffraction grating is united between the sides of lens blocks 3 of optical module units 1 and 6 opposed to optical fiber blocks 2. Only light with a wavelength λi among light (wavelength components: λ1, λ2 . . . λn) from an optical fiber 41 is transmitted through the wavelength division element 32 and enters an optical fiber 42 of the optical module unit 6. On the other hand, the light (wavelength components: λ1, λ2 . . . λn-λi) reflected at the wavelength division element 32 is taken out of an optical fiber 43 of the optical module unit 1.
