Abstract
The present invention relates a fiber optical module. A first filtertransmits a light with a first predetermined wavelength (λ), and reflects lights with a second predetermined wavelength (λ) and a third predetermined wavelength (λ). A second filtertransmits the light with wavelength λand reflects the light with wavelength λ. A first light-receiving devicereceives the light with wavelength λ, and a second light-receiving devicereceives the light with wavelength λ, A light-emitting deviceemits the light with wavelength λ. A first optical fiberleads the lights with wavelengths λand λto the first filter. A second optical fiberleads the light with wavelength λreflected by the first filter. A third optical fiberleads the light with wavelength λemitted by the light-emitting deviceto the second filter
