Abstract
In accordance with the invention a multiwavelength optical fiber transmission system is provided with a passive all-fiber optical router for add/drop multiplexing. The passive router is comprised of three fiber components: 1) a fiber directional coupler, 2) a fiber reflective grating filter and 3) a fiber notch filter. The specification describes optical routers from these components ranging in complexity from a three wavelength router to an N-wavelength router.
